Last week we got our first set of Samsung Galaxy Tab A4S specs – an upcoming mid-range tablet from the Korean manufacturer. The tablet was certified by the Bluetooth SIG bearing the SM-T307U model number and was previously spotted on the Wi-Fi alliance database.
The new certification reveals the tablet will sport an 8.39-inch display and a 4,860 mAh battery with 15W fast charging. In addition, the Tab A4S will come with GPS, LTE and dual-band Wi-Fi 802.11 ac. The tablet measures 201.9 mm by 124.4 mm and runs Android 9 Pie.
Samsung still hasn’t provided any official teasers about the Galaxy Tab A4S but according to speculation, we might see the device get unveiled at CES 2020 which is next week.
The ThinkPad T490s (note the s) is a slimmer take on the already slim ThinkPad T490, both of which are 14-inch models in Lenovo’s current ThinkPad lineup.
It seems to fit somewhere between the standard T-series and ultra thin-and-light X-series laptops from Lenovo, and any way you look at it the T490s is a slim and very lightweight business machine.
Another aspect of the T490s is the variety of display options available, from low-power FHD panel of our review sample all the way up to a WQHD option featuring Dolby HDR support.
But the best part of this design? Though it carries the ubiquitous “thin-and-light” label, the T490s actually offers legitimate I/O support in the era of USB-C-only laptops.
T490S DESIGN
The case material is the familiar ThinkPad combination of carbon fiber-reinforced plastic and magnesium alloy, and this version of the T490s measures 12.94 x 8.85 x 0.63 inches and weighs just 2.81 lbs (there is some variance based on display panel configuration).
And now for a look at the all-important I/O, which is significantly above average with the ThinkPad T490s compared to other laptops in the “thin-and-light” category. No, it’s not quite up to the level of the full-sized T-series models, but we aren’t talking about yet another slim laptop with just a pair of USB-C ports, either.
From left to right we have the USB-C AC power input, USB-C Thunderbolt 3 port, Ethernet (requires optional Ethernet Extension Adapter), USB 3.1 Gen1 port, HDMI output (1.4), and 3.5 mm headphone/mic combo port.
On the other side we see, again from left to right, an ExpressCard slot for an optional Smart Card reader, another USB 3.1 Gen1 port (this one offering Always On power for charging), and a Kensington lock slot.
The rear of the T490s is where you’ll find this model’s combo MicroSD card reader/micro-SIM slot.
The front edge of the laptop’s lid houses the slider for the physical camera cover (ThinkShutter).
While this is a not a 360-degree hinge design like the Yoga series, this ThinkPad offers a hinge that allows the display to fold nearly flat:
Next up we’ll check out the all-important input.
INPUT
Long-time ThinkPad users have very strong opinions about their laptops, particularly when it comes to input. Here I decided to compare the T490s to recent ThinkPads and other thin-and-lights that I have used.
KEYBOARD
The keyboard is comfortably wide, with slightly concave key caps that help make these feel a bit more traditional. The key travel is still fairly shallow, but still deeper than most chiclet-style options out there. I found this model to feel almost exactly like my trusty ThinkPad Yoga S1’s keyboard, which is to say it’s very, very good.
The keyboard is also spill resistant (though I was not brave enough to test this out before I had to send it back), and our review unit featured LED backlighting. I really don’t have any complaints here.
ULTRANAV AND TRACKPOINT
The buttonless touch pad (UltraNav) offers a smooth multi-touch surface that feels good, though not up to the level of the large glass touch pads on Apple machines. That unpopular Apple reference aside this did feel quite good and was very responsive, and I had zero issues with it.
For its part the TrackPoint “nub” felt like any other ThinkPad’s TrackPoint I’ve personally used. Some people will prefer this method, and you do get physical buttons for left and right click at the top of the touch pad just below the space bar. Tracking felt as precise as ever.
I found myself favoring the TrackPoint for certain types of work including photo editing, while I defaulted to the touch pad for things like web browsing, where I appreciated the solid implementation of two-finger scrolling.
DISPLAY
Without doing a thorough analysis I can only offer subjective impressions here, and the low-power FHD display on our sample was excellent. It offers a matte surface that was pretty good at rejecting glare, but I was immediately struck by its rich color and what I thought was very good accuracy out of the box (especially for a business machine that isn’t marketed toward creative professionals).
Lenovo doesn’t provide specifics about the Low Power FHD panel in our sample, other than the fact that it is IPS. I have seen it suggested that they may be using IGZO technology for this low-power variant (in the Notebook Check review), and going all the way back to 2016 when I experienced my first IGZO display (with the Dell XPS 15) that seems right. There’s just something about the color, which I would describe as a quasi-OLED effect.
PERFORMANCE
I set out evaluating this laptop by simply using it as my daily driver for a few months. I used the T490s exclusively over this past summer (keen-eyed observers may have noticed a system date from way back in July in the photos of the system), and I continued to use the machine until the end of August.
This isn’t new information, but honestly there is nothing earth-shattering about performance numbers from a notebook with an 8th-Gen Intel Core i5 mobile processor. The most important aspects of a laptop (to me, anyway) have nothing to do with compute performance, and everything to do display and input quality – and of course battery life.
I did run the PCMark 10 Extended benchmark (and a couple of others) for reference, and provide the results below for anyone interested. One thing of debatable interest was the x264 benchmark, which I’ll admit right now is a terrible idea for a mobile benchmark – just like Cinebench. How many people are rendering or transcoding with their laptop? (Unless it’s their only PC, of course.)
After the first pass of the first iteration (of four consecutive) of the x264 benchmark, the CPU performance dropped considerably as thermal/power management kicked in (from the benchmark’s text output):
Pass 1
encoded 11812 frames, 79.49 fps, 7754.22 kb/s
encoded 11812 frames, 69.55 fps, 7754.21 kb/s
encoded 11812 frames, 69.32 fps, 7754.22 kb/s
encoded 11812 frames, 69.30 fps, 7754.32 kb/s
We’re talking a drop from 79.5 to 69.5 FPS immediately, which stabilized at around that 69 FPS number after that. What does this mean? It means don’t use a laptop for video transcoding unless you have to.
In closing, performance with an 8th Gen Core i5 processor is just fine for most tasks, and you only run into problems if you want to do something very CPU or GPU intensive – particularly the latter. There is no discrete GPU option with the T490s, and a Core i5-8265U processor limits you to Intel UHD 620 graphics. This isn’t going to take you very far up the resolution/detail settings ladder, but this is a business machine after all (though it runs DOSBox like a champ, which is all that really matters anyway).
CONCLUSION
I used a number of laptops in 2019, and this ended up being my overall favorite. No, it’s not a big gaming beast with a mechanical keyboard and desktop GPU inside, nor is it an impossibly slim aluminum lifestyle accessory with zero connectivity. The ThinkPad T490s exists in this happy medium of professional machines where at least some of the I/O we used to take for granted is still built in to the device itself, and doesn’t exist only in one’s imagination (aka a series of dongles).
Can it be argued that an extra-slim T-series machine from Lenovo is really a T-series machine, considering concessions to size such as the need for an optional adapter for Ethernet? I wasn’t hung up on the branding of the laptop, so I won’t argue either way. To me it was just a solid business-oriented laptop with a great display, great input, and great battery life. And it was super lightweight. What more can you really ask for from a work laptop?
Now we come to an aspect of the T490s that I didn’t get into in the review as I was evaluating a single variant of this model: there are a lot of different configurations available. A ThinkPad T490s as reviewed is about $1700, but a T490s actually starts at around $1399, and there’s even a T495s variant with AMD processors available now (starting at ~$1050).
I would certainly recommend that anyone check out this T490s/T495s product family if they are in the market for a lightweight productivity laptop that doesn’t require carrying around a series of dongles everywhere you go. The T490s might not be what long-time T-series users think of as a “T-series” laptop (it’s probably more like a thicker X-series), but regardless of the designation it’s a damn good laptop.
The popular messaging app WhatsApp looks set to introduce four new features in 2020. Here’s everything we know is coming down the pipeline.
The Facebook-owned chat app, which is used by 1.5 billion users every month, has introduced a number of new features over the last twelve months, including the ability to choose who can add you to a group chat, respond privately to a message sent inside a group chat, and protect your chats with a fingerprint on Android smartphones.
With the app constantly updating its software to include a slew of new features to provide smooth messaging and call experience to its users, here’s a breakdown of the new features that look set to arrive over the next 12 months.
Dark Mode
WhatsApp’s elusive Dark Mode has been rumoured for 18-months now and looks set to finally arrive in 2020. WABetaInfo – a popular Twitter account that deep-dives through the latest beta releases of the app to uncover clues about forthcoming features – discovered the first hints at the gloomier appearance in summer 2018.
Since then, we’ve seen an increasing amount of evidence about the feature, including the fact that WhatsApp is purportedly looking to create two new potential looks – one in greyscale, and another in pitch-blacks. Twitter uses a similar approach. While the pitch-black tones will be the only ones that act as a battery-saver for those with smartphones touting OLED touchscreens, the greyscale should still help people who are only looking to ease their eyes when using their smartphones late at night.
Interestingly, every other Facebook-owned platform which has introduced a Dark Mode has opted for the jet-black variant, including Instagram and Facebook Messenger. Both of these were also much, much quicker at getting the feature out the door – so it really seems like WhatsApp is doing its own thing here.
For those who don’t know, Dark Modes switch the portions of the user interface that would typically be white with greys or blacks. This is designed to make your smartphone screen less glaring when using it at night or other low-light conditions and eking out a few more hours battery life when used on a smartphone with an OLED panel.
Although WhatsApp’s Dark Mode is still in the works (with no confirmed release date as yet) WABetaInfo has reported that the dark theme update is ready for the android version of WhatsApp.
Self-Destructing Messages
Discovered by @WABetaInfo once again, WhatsApp appears to be working on a SnapChat-inspired new feature that will let you set a timer on your texts. The new feature means users can send messages that will self-destruct after a certain time has passed.
The Facebook-owned team looked set to brand the feature “Disappearing Messages,” which wasn’t the most thrilling name. Something that WhatsApp appeared to think too because it changed the name to “Delete Messages” as of the 2.19.348 update.
Group chats will be able to set a blanket rule about Delete Messages – so that every text message, photo, video vanishes after either one hour, one day, one week, one month or one year. It’s a fun way to make sure that you’re not constantly haunted by the texts, videos or photos that you’re sending to an individual or group.
SnapChat gained huge traction for its ephemeral messaging system, which removes every photo, video, text message after a recipient has read it. To prevent people from being able to screenshot anything the sender might’ve wanted to keep as a limited time only offer, the messaging app included a warning when the other person in your chat screenshots the messages. It’s unclear whether WhatsApp is working on a similar warning.
Clearly, WhatsApp is still working hard on the feature. It has not announced plans to offer Disappearing Messages, so it might be a while before we see the finalised feature roll-out.
Adverts Are on the Way
Yes, we’re afraid it’s not all good news about the updates planned for 2020. While the Facebook-owned app looks set to introduce a slew of new features and capabilities, there will also be some adverts in the app for the first time. Rumblings about advertisements coming to WhatsApp have been around for some time (and are believed to be one of the reasons that WhatsApp co-founder Jan Koum left the company after its acquisition by Facebook).
Luckily, the adverts won’t be coming to the chat windows themselves – so you don’t have to worry about ducking around adverts for discounted holidays while you’re texting your mum. Instead, the adverts will be played in-between slides on WhatsApp Statuses – just like they are on other Facebook platforms, including Instagram.
Shopping Brochures For Your Chat App
WhatsApp is bringing shopping catalogues to its WhatsApp Business app. The software, which is an off-shoot of the original chat app designed to help customers communicate with businesses or customer service representatives using the same tools as the normal chat app, is available worldwide.
Dubbed Catalogs (yes, they’re using the American spelling), merchants on WhatsApp Business can now share a complete breakdown of their inventory that you can peruse within the same chat app window you’d usually use to speak with business owners. Weirdly, you’re not able to buy anything from the catalogue just yet.
However, given the announcement that Facebook is launching its own payment service (inventively named Facebook Pay) and that it will be coming to WhatsApp in the future, it seems more than likely that chat app users will eventually be able to buy an item from the catalogue without ever leaving WhatsApp.
But for now, WhatsApp claims the new feature is designed to help small businesses appear more professional on the app. If a merchant isn’t able to offer a slick online catalogue of all of their items, WhatsApp’s new tool should let them present their customers with a beautifully-designed catalogue of everything in-store without much effort – or programming – on their part.
Shopping catalogues on WhatsApp Business have started to crop-up in the UK, United States, Brazil, Germany, India, Indonesia, and Mexico. But for everyone else in the world, this is a 2020 feature – so keep an eye out for the update coming to your app soon.
Of course, Express.co.uk will cover all of these announcements as soon as they happen. So stay tuned for all the latest announcements from WhatsApp.

What is the run time of Sony battery?
Sony batteries have two main ratings on them: Volts and Amperes. Because size and weight of batteries is limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Milliamperes. One thousand Milliamperes equals 1 Ampere. When buying a battery, select batteries with the most Milliamperes (or mAh). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together. For example:
14.4 Volts, 4000mAh (Note: 4000mAh is equal to 4.0 Amperes).
14.4 x 4.0 = 57.60 Watt-Hours
Watt-Hours signifies the energy needed to power one watt for one hour.

One thousand Milliamperes equals 1 Ampere. When buying a battery, select batteries with the most Milliamperes (or mAh). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together. For example:
14.4 Volts, 4000mAh (Note: 4000mAh is equal to 4.0 Amperes).
14.4 x 4.0 = 57.60 Watt-Hours
Watt-Hours signifies the energy needed to power one watt for one hour.

When the H305P-02 AC adapter (charger) fails to work, it will neither charge the Servers battery nor provide power to operate the Servers without battery power. Power issues on a Servers are compounded because a Servers has two power sources: AC adapter (charger) & battery. When H305P-02 power is not available, power is provided by the Servers battery.
If you’re having issues with your H305P-02 adapter not charging your Servers, please try to follow these steps to solve the problem.
Inspect the H305P-02 AC adapter, cables and adapter (DC) port on the Servers for damages
Unplug the H305P-02 AC adapter from the wall outlet.
Disconnect any external peripherals connected to the Servers.
Press and hold the Power button for 30 seconds to drain a residual power from the Servers.
Plug the H305P-02 AC adapter into the Servers.
Turn on the Servers. If your Servers still can’t strat, you need a new H305P-02 ac adapter.
11 Tips On Choosing The Correct H305P-02 Servers Charger
It is not difficult to find the correct H305P-02 Servers charger if you are ready to do a little research. Many people end up purchasing wrong Servers chargers from the internet simply because they do not set aside enough time to look for the correct information. To help you in this regard, the following is a compilation of some important tips on finding the right H305P-02 charger for your Servers:
1. Before you make up your mind to buy a new charger, make sure you check the H305P-02 Servers power supply and detachable wires for any faults. Just make sure that your charger is indeed faulty before you decide to place an order either online or offline.
2. Serverss in a series may or may not have the same H305P-02 charger. Different models manufactured by a company have different specifications. Always keep the compatibility aspect in mind while making such purchases.
3. You must scout for the correct information. Finding Servers chargers can be an extremely convenient process if you have the right information. This information can be found on your Servers or the old Servers charger very easily. Note down the manufacturer’s information labelled on your old H305P-02 charger. Use this information when you perform an online search.
4. If you are going to purchase from a local computer or electronics store, look carefully at the list of all computer models compatible with a H305P-02 charger under consideration. Servers chargers generally come with a list of various Servers makes.
5. Turn your Servers face down and note the product information stamped by the manufacturer. These specs are provided on different parts of the Servers. Look for the product specification stamp that reads something along the lines of ‘AC Adapter.’ That is where you can easily find the correct model number of all chargers.
6. Make sure you have the right pin connectors while purchasing a H305P-02 charger for your Servers. These pins should be compatible with your existing wall sockets. Charging your Servers can be a bother with a new charger if its pins do not fit into your room’s wall sockets.
7. You can find a Servers charger with additional features. These days, it is possible to find chargers that trip the Servers power supply as soon as there is a voltage fluctuation. These chargers are great, especially if you live in an area where power fluctuations are frequent.
8. It is possible to find a universal charger nowadays since many manufactures are selling one-for-all chargers. These Servers chargers are fine as long as you find one that is compatible with your Servers.
9. Always check the voltage, input, and output before buying any charger. These details are labelled on the product packaging. Make sure this information is in keeping with the specs of your Servers.
10. Do not be tempted by unbelievably low prices on some websites as you may end up placing an order for a duplicate product. Always buy Servers chargers from a reputed or professional site.
11. In principle, the more authentication the more reliable the adapter is. Don’t buy a compatible H305P-02 adapter with few certifications, it will hurt your machine.
How to do when ac adapter buzzing noise?
Buzzing in an AC adapter can mean a number of things, but often it is related to a damaged adapter, poor grounding or phasing issues with your power. Figuring out exactly why your AC adapter is buzzing will probably require some troubleshooting, but in the end you can probably isolate the problem and get rid of the frustrating noise.
Check for any obvious damage to the adapter. If any of the outer rubber coating has been damaged so that the conductor inside is exposed, this could allow interference to enter the current and cause a buzzing sound. Untie any knots if the cord has become knotted. Make sure that the connection where the cord meets the actual box adapter is still intact; this sometimes can become damaged and make a poor connection.
Repair any damage with electrical tape. Cover all exposed areas.
Plug the AC adapter into the same outlet as the other equipment you are using. Some apartments and houses have multiple phases of power that can create audio interference if mixed together, so running everything off of the same phase might get rid of the buzz.
Run your equipment through a surge protecting power strip or, if necessary, a power conditioner. Audio and video equipment is especially susceptible to interference caused by ground looping. A power conditioner will smooth out the current and protect your equipment from any peaks or spikes in current.
Why laptop adapter light blinks?
Question description:
A few days ago studying in the UH library, I noticed my laptop all of a sudden wasn’t receiving power and the light my AC adapter was blinking. After unplugging it from the laptop, that is, from the power jack, the AC adapter’s light turned solid green again. Then, as you might guess, after plugging it back into the laptop’s power jack, the light on the adapter would again start blinking and no power would circulate.
After brief research, I learned that I could take the battery out and press the power button to relieve all currents and that after that everything would work fine. Well, I did get it to work, however not my this method. After trying it several times and failing, I figured I’d just use the laptop without the battery, since it powered the laptop without the battery in it. Then the idea of just placing the battery back in the laptop while I was receiving power came up. So as the laptop is working I placed the battery in and SUCCESS the AC adapter no longer was blinking and it was successfully transferring power to the laptop and battery.
Now, however, several days later, in a similar library, I noticed I wasn’t receiving power again. When I unplugged the adapter from the laptop, the light on the adapter continued to blink. This was not the case previously. Previously, the light on the adapter would only blink when plugged into the laptop and would turn solid green when I disconnected it from the laptop. Now however, without the laptop ever coming into the picture, the AC adapter, by itself, not plugged into anything other than the wall, constantly blinks. The laptop receives no power, and I’m stuck.
Also, used my sisters AC adapter, she has a similar laptop, and everything worked fine. Meanwhile, my AC adapter, while plugged into the same power jack in the wall, just blinks.. and blinks…
someone help.
Answer:
The AC adapter’s light turned solid green means ac adapter have a solid out put. When the light blinking, it means that the adapter is trying to output again and again, and it keeps flashing to indicate that the output was failed. You need check laptop dc jack or a MOSFET on laptop motherboard. Usually one laptop model develops this kind of fault and then many of the same model start to fail.
Mirrorless cameras may be all the rage in 2020, but both Canon and Nikon aren’t keen on seeing DSLRs disappear, with a successor to the now five-year-old Nikon D750 likely to join the ranks this month.
According to reliable camera news leaker Nokishita, Nikon is preparing to announce what will likely be designated the D780 “soon”, along with another CoolPix shooter and two new lenses.
Translated, the above tweet says that Nikon has updated its product list in overseas markets (exactly where is as yet unknown) to include the D780, a CoolPix P950 superzoom bridge camera, an AF-S Nikkor 120-300mm f/2.8E lens and a Z series 70-200mm f/2.8 lens. Although the tweet states that the products will be “announced soon”, unconfirmed reports suggest that the official announcement date will be January 7, the first day of CES 2020.
2020: A big year for DSLRs
The first we heard about an upgraded version of the D750 was back in November 2019, when some specifications were revealed but not the name of the highly anticipated model.
The upcoming full-frame DSLR is said to have a 24MP back-illuminated sensor for better low-light performance and an improved imaging processor. That means the camera will be capable of 4K/30p video recording.
While the D780 will reportedly feature the same 51-point autofocus (AF) system as the older D750 and D850 when focusing via the viewfinder, when shooting in live view (with the mirror up) the D780 is rumored to use the same 273-point on-sensor phase-detect AF system as the Nikon Z6.
Nikon Rumors speculates that the D780 will cost somewhere between $1,999 and $2,199, putting it not too far from the $2,300 launch price of the D750 back in 2014.
However, all the latest information on the possible D750 successor is still rumors on the grapevine – although if there’s any truth to the early January launch date, then all will be revealed very soon indeed.
Dell’s Inspiron line of laptops may not be its most premium family, but that hasn’t kept some of the best features and performance hardware from showing up here.
The Dell Inspiron 13 7000 2-in-1 Black Edition (or Dell Inspiron 7390) is a testament to that, with exclusively high-end internals, a premium design, a 4K display, and a clever stylus slot that makes us wonder whether they actually beat Microsoft to the idea.
Price and availability
The Dell Inspiron 13 7000 2-in-1 serves as a launching point for Dell’s latest Inspiron 13 7000-series laptops. That’s because Dell was quick to move on from this model. It was effectively the ultimate version of the Inspiron 13 7000-series just before Dell took the leap into 10th-Gen Intel Core processors.
As a result, Dell has already ended sales of this model, but much of what Dell has put into this Black Edition model shows up in the newest Inspiron 13 7000 2-in-1 (7391), with the closest configuration costing $1,299 (about £985, AU$1,905). That new model offers an 10th-Gen Intel Core i7-10510U processor (a decent upgrade), the same 16GB of RAM, an equivalent 512GB SSD with 32GB of Intel Optane Memory, and 4K touch screen with Dell Active Pen support, and an upgraded Wi-Fi 6 connection. The design remains nearly unchanged, but Dell has upgraded the USB-C port to Thunderbolt 3.
The pricing runs the Dell Inspiron 13 7000 2-in-1 against a lot of devices in the ultrabook category. The HP Envy 13t starts at $999 (£849, AU$1,799) but is often available with considerable discounts, though the price would go up to offer similar specs to the Inspiron we’ve listed. Meanwhile an HP Envy x360 15 with comparable specs (but a Full HD display) starts at just $1,199 (about £910, AU$1,760).
The price even runs the Inspiron up against Dell’s XPS lineup. The Dell XPS 13 we reviewed had near equal internals to the Inspiron model we have on hand, but cost a staggering $2,279 (about £1,730, AU$3,345) at the time. And, while Dell has also updated the XPS line to include 10th-Gen Intel Core processors, the prices have remained relatively stable.
Design and display
The Dell Inspiron 13 7000 2-in-1 certainly qualifies as a thin-and-light ultrabook, but it’s not the thinnest, lightest, or most ultra. The 2-in-1 form factor often comes with a tradeoff in weight and thickness, and that shows up here. The Dell Inspiron 13 7000 2-in-1 Black Edition measures 0.63 inches (15.9mm) at its thickest point and weighs 3.1 pounds (1.39kg). That’s well above the 2.7-pound XPS 13 and 2.59-pound HP Envy 13t.
That said, the Dell Inspiron 13 7000 2-in-1 Black Edition is plenty easy to carry around. It fits well into the laptop slot in our backpack, and does little to weigh us down. We’ve definitely borne heavier laptops.
One thing likely contributing a bit to the weight is the metal chassis. While some laptops opt for a lighter magnesium, Dell has gone with stamped aluminum. It feels sturdy to the touch, with minimal flex when we apply pressure. That aluminum covers the bottom, display cover, keyboard deck and outside of the hinge, but the inside of the hinge is plastic.
There’s a good excuse for the inside of the hinge being plastic: that’s where the Dell Active Pen lives. It has a handy slot carved out for it, and is held firmly in place by magnets. The magnets are strong enough that we’re able to roll the pen across the keyboard and have the magnets pull it right into the slot. It’s a clever solution that makes losing the pen difficult while also making it easy to access the pen in any position.
That’s important because the laptop can be in several positions. It can fold open into a tablet, sit upright like a typical laptop, or flip over into a tent position. In all of those orientations, the pen is readily available.
This design positions the barrel charging port on the left side along with an HDMI and USB-C port, making the ports nice and balanced. The right side houses a USB-A port, 3.5mm headphone jack (something we firmly believe belongs on the left side of laptops but is more excusable in a 2-in-1 where the left and ride side can flip), and a microSD card slot.
Dell has positioned large speaker grilles on the underside of the chassis, near the front, but they may not have very big speakers inside. The audio is wimpy, with the low-end almost absent, and higher volumes leading to an irritating buzzing.
The display helps make up for the speakers somewhat. It’s impressively clear at 4K, though it could stand to be brighter. The maximum brightness is strong enough for a lot of situations, but the glossy display sets it up to fail against sunlight. The bezels on the sides and top are fairly thin, though the top bezel makes a bit more room for the 720p webcam. The lower bezel is easily an inch wide. It’s not bad, but it’s not winning any screen-to-body ratio competitions.
Playing a Blu-ray copy of Guardians of the Galaxy, the visuals look excellent on this display. It holds up for video consumption. We do notice a quirk when running into high-contrast situations. In our usual work setup, we have two windows open side by side, often articles (i.e., a lot of text and white space). When one of those windows has a dark image, we notice all of the whole display dim slightly. We can see this at max brightness and lower brightnesses as well.
The input devices on the Dell Inspiron 13 7000 2-in-1 Black Edition are a strong side of the experience. The trackpad is smooth and responsive, and has plenty of space for navigation and even four-finger gestures. As for the keyboard, the keys could benefit from some contour, but otherwise feel good and poppy to type on. Dell avoids any buffoonery around the arrow keys, keeping a full-size Shift key and positioning narrow arrow keys below it. The only nuisance from the keyboard is the fingerprint scanner/power button. It’s in the top right corner of the keyboard, inconveniently pushing the Delete key out of the way.
Thanks to some pressure sensitivity, the pen is capable of a lot, and the only downside we notice is that when pressing very lightly against the display, it can fail to register, as can very quick movements across the screen (though this varied by which app we drew on).
Performance
The Dell Inspiron 13 7000 2-in-1 Black Edition isn’t a performance monster with the Intel Core i7-8565U processor and integrated graphics on offer, but it’s perfectly sufficient for the type of work it’s expected to handle. The processor zips through simple tasks, booting, and program launches quickly.
In our Benchmarks, we see the processor running neck and neck with the same chip in more expensive laptops like the Dell XPS 13 and cheaper HP Envy 13t, and considering the 16GB of RAM, this is a multi-tasker worth looking at. We don’t run into any issues working on projects with dozens of tabs open in Chrome, the occasional YouTube video, and Slack in the background all at the same time.
Through all of our work with the Dell Inspiron 13 7000 2-in-1 Black Edition, we haven’t noticed it get very warm either. The fans kick up to a modest level when it’s under load, but they’re not obnoxiously loud.
Graphics are one shortcoming for the Dell Inspiron 13 7000 2-in-1 Black Edition. The use of integrated graphics limits its potential for any graphical workloads. Compared to our HP Envy 13t running the same CPU but paired with an Nvidia MX250 2GB graphics processor, the Dell Inspiron 13 7000 2-in-1 Black Edition simply gets smoked in graphics related benchmarks like our suite of 3DMark tests. It does manage to perform mostly in line with the similarly configured Dell XPS 13, showing how narrow the line between products can get
Battery life
While normally the use of integrated graphics might seem like a smart consideration for battery life, our benchmarks showed a different story here. The Dell Inspiron 13 7000 2-in-1 Black Edition earned a respectable PCMark 8 Battery Life score of 5 hours and 32 minutes, exceeding the Dell XPS 13’s and nearly tying the HP Envy 13t’s scores.
That’s good news for workers, as that test simulates working and browsing. In our experience using the Dell Inspiron 13 7000 2-in-1 Black Edition for work, it holds up well for most of a day when keeping the power settings lower and leaving the display at 50% brightness. A full 8-hour work day would be a bit of a stretch, but could likely be managed with further reduced brightness and battery-saver mode.
When the battery is low, the laptop supports fast charging to top it back up quickly. We managed to get the battery from empty up to 86% in a little over 90 minutes while working with the screen brightness at max and the power mode set to best performance..
Media lovers have a little less to love about the computer. In our video test, which loops a 1080p video with the display at 50% brightness until the battery dies, we only got 5 hours and 42 minutes of playback – likely thanks to the 4K display. The Dell XPS 13 with a 4K display does manage a bit longer at 8 hours and 12 minutes, but the HP Envy 13t with its Full HD display doubles the Dell Inspiron 13 7000 2-in-1 Black Edition’s playback time, showing that the MX250 graphics don’t have much of a downside.
Final verdict
The Dell Inspiron 13 7000 2-in-1 Black Edition is a versatile machine that will make a reliable partner for workers of all types. The ability to multitask, take notes with the stylus, and enjoy sharp content on the display add up to a strong experience. A Full HD display option would likely improve the offering, but the introduction of new 10th-Gen Intel Core processors to the Dell Inspiron 13 7000 2-in-1 line might improve the battery shortcomings while offering more configurations.
