25 Baronial 2020 / 08:27 | 0

Oftentimes times, 15-inch two-in-1 laptops are not really practical. They are heavy, hard to handle, and just too spacious. Nonetheless, they accept 1 big advantage – a big touchscreen. So, if you lot demand the touchscreen adequacy, and you want to work with a defended Pen, this would be a decent option, right?

Well, this should exist the case with the Ideapad Flex 5 (fifteen). It not just has a lot of screen real estate, but information technology comes with an optional Lenovo Digital Pen inside of the box. Additionally, it can be outfitted with the best ULV processors Intel provides – the 10nm Ice Lake chips. Moreover, the highest possible tier is the Core i7-1065G7, which has a pretty remarkable integrated graphics solution.

What'south in the box?

Inside the package, nosotros got a 65W power brick, some paper manuals, and an optional Lenovo Digital Pen.

Design and construction

As with whatever fifteen-inch notebook, the footprint is quite large for a convertible. However, the laptop also weighs i.80 kg and has a profile of 17.nine-twenty.9mm. Ultimately, this would be a perfect combination for a conventional device, but for a 2-in-i – information technology feels a bit on the heavy side. In terms of build materials, the lid cover is fabricated out of aluminum, while the rest of the notebook comes in a plastic shell. Its also worth mentioning that the base has some sort of a textured finish, which feels a scrap grippy.

To no surprise, the chapeau doesn't open up with a unmarried hand. Also, the hinges are not very stable in an upright position and you will accept a hard time using the touchscreen similar that. Thankfully, the display has a drinking glass embrace, which greatly increases the resistance to flex. Past the way, the touchscreen and the Pen use Wacom drivers out of the box, and the HD camera has a privacy shutter.

However, the base of operations provides a very different feel. Information technology twists, the keyboard deck bends and it by and large feels soft. Naught unexpected, though. As we mentioned, information technology is entirely made out of plastic. Equally of the keyboard, itself, it has comfortable feedback, but the fundamental travel is a bit also curt. On the brilliant side, it features a NumberPad department, besides as a fingerprint reader.

Beneath the keyboard, you will find the Mylar touchpad. This term means that the material used for the surface is made out of a plastic sail, which has very similar properties to glass. This gives the touchpad very nice gliding, while the tracking is besides decent.

Instead of having its speakers firing downwards, the Ideapad Flex v (15) actually has its shooting towards the user. This leaves the bottom plate merely dwelling to the ventilation grill, while the hot air is exhausted from the back.

Ports

This notebook has its Power plug, HDMI one.4b connector, USB Type-C iii.ii (Gen. 1) port, an audio jack on the left, every bit well every bit two USB Type-A 3.two (Gen. 1) ports, and SD card reader on the right.

Disassembly, upgrade options and maintenance

This device's bottom panel is held in identify past 9 Torx-head screws. Every bit the saying goes, after undoing them, you need to pry the lesser panel with a plastic tool.

Since our unit is not equipped with a detached GPU, there is only one heat pipage, which is relatively sparse. Thankfully, the area of the rut sink is quite big, and then cooling should not be a problem here.

On the downside, the RAM modules are soldered to the motherboard, so there are no upgrades possible in this aspect. The maximum capacity you tin get is 16GB of 3200MHz DDR4 memory. However, there is 1 M.ii PCIe x4 slot for fast storage.

Bombardment-wise there is a 52.5Wh unit.

Brandish quality

Lenovo ThinkPad Flex 5 (15) is equipped with an IPS panel, model number AUO B156HAN02.5 (AUO25ED). Its diagonal is 15.6″ (39.62 cm), and the resolution 1920 х 1080 pixels. The screen ratio is 16:9, and we are looking at a pixel density of – 142 ppi, and a pitch of 0.eighteen х 0.eighteen mm. The screen turns into Retina when viewed at distance equal to or greater than 60cm (24″) (from this altitude ane'south eye stops differentiating the separate pixels, and it is normal for looking at a laptop).

Viewing angles are excellent. We offer images at 45° to evaluate paradigm quality.

The measured maximum effulgence of 287 nits in the middle of the screen and 292 nits every bit an average for the whole expanse, with a maximum deviation of 16% (pinnacle right corner). The Correlated Colour Temperature on a white screen is 6120K – slightly warmer than the optimal for the sRGB standard of 6500K.
In the illustration below you can see how the display performs from a uniformity perspective. In other words, the leakage of calorie-free from the light source.

Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should bank check if you intend to use the laptop for colour-sensitive work. The contrast ratio is proficient – 1200:ane.

To make sure nosotros are on the same page, we would like to give you a little introduction to the sRGB color gamut and the Adobe RGB. To beginning, at that place's the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors past the man eye, giving you lot a meliorate perception of the colour gamut coverage and the color accuracy.

Inside the blackness triangle, you will see the standard color gamut (sRGB) that is beingness used past millions of people in HDTV and on the spider web. As for the Adobe RGB, this is used in professional cameras, monitors, etc for printing. Colors inside the black triangle are used by everyone and this is the essential part of the color quality and colour accuracy of a mainstream notebook.

Still, we've included other color spaces similar the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. Rec.2020, withal, is yet a thing of the futurity and it's difficult for today's displays to encompass that well. We've also included the so-chosen Michael Pointer gamut, or Pointer's gamut, which represents the colors that naturally occur around united states every day.

The xanthous dotted line shows Lenovo ThinkPad Flex 5 (fifteen)'s color gamut coverage.

Its display covers only50% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976.

Our "Pattern and Gaming" profile delivers optimal color temperature (6500K) at 140 cd/m2 luminance and sRGB gamma mode.

We tested the accurateness of the brandish with 24 commonly used colors like light and dark human pare, bluish heaven, green grass, orangish, etc. You can check out the results at manufactory condition and likewise, with the "Blueprint and Gaming" contour.

Below you tin compare the scores of Lenovo ThinkPad Flex 5 (15) with the default settings (left), and with the "Gaming and Web design" profile (correct).

The next figure shows how well the brandish is able to reproduce really dark parts of an paradigm, which is essential when watching movies or playing games in depression ambient calorie-free.

The left side of the image represents the display with stock settings, while the correct one is with the "Gaming and Web Design" profile activated. On the horizontal axis, you will find the grayscale and on the vertical axis – the luminance of the display. On the ii graphs below you can hands check for yourself how your display handles the darkest nuances merely continue in heed that this too depends on the settings of your electric current display, the calibration, the viewing angle, and the surrounding light weather condition.

Response time (Gaming capabilities)

We test the reaction time of the pixels with the usual "black-to-white" and "white-to-black" method from 10% to 90% and vice versa.

Nosotros recorded Autumn Time + Rise Fourth dimension =24 ms.

PWM (Screen flickering)

Pulse-width modulation (PWM) is an piece of cake way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, merely instead turned off and on by the electronics with a frequency indistinguishable to the human being heart. In these light impulses, the low-cal/no-calorie-free time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You tin read more about that in our dedicated article on PWM.

Lenovo ThinkPad Flex 5 (15)'s display doesn't use PWM to adjust its effulgence levels. This ways it is safe for long workdays, without presenting any strain in your eyes in this aspect.

Blue light emissions

Installing our Wellness-Guard profile not only eliminates PWM simply besides reduces the harmful Blue Low-cal emissions while keeping the colors of the screen perceptually authentic. If you're not familiar with the Blue lite, the TL;DR version is – emissions that negatively affect your optics, skin, and your whole body. You tin can notice more information about that in our defended article on Bluish Light.

Decision

Lenovo ThinkPad Flex 5 (xv)'s touchscreen IPS console has a Full HD resolution, comfortable viewing angles, good contrast ratio, and a non-flickering backlight. Although it is safe for long periods of use, the console has a relatively poor colour representation, with only l% of sRGB coverage, uneven luminance beyond the area of the screen, and colour accurateness, which is worse than being colour-bullheaded.

So, we ran this exam at the Extreme performance preset, and these are the results we got. The cooling is surely one of the more than modest ones out there. But as the synthetic benchmarks have proved, information technology happens to be just enough.

Comfort during full load

So the skillful thing is that while the fan is clearly aural, it is not too loud. Neither does the laptop get too hot to touch.

Verdict

Thankfully, the Wacom drivers seem to be working perfectly, which means that the laptop works bully with its Lenovo Digital Pen. So, if you happen to be in need of a 2-in-one device with a lot of existent estate, the Ideapad Flex 5 (15) would do a decent chore.

Aye, it'south a little scrap heavier than what we would similar, and its memory is soldered to the motherboard (which ways no upgrades) but the overall experience is great. Also, using it in the "Extreme Functioning" preset, we establish it to perform extremely well. Also, if you have the upkeep, we would advise going for the Core i7-1065G7 and 16GB of memory option, as it would deliver the ultimate operation/longevity of the product.

Speaking of advice, the 1080p panel of this notebook is something that should be avoided. Lenovo ThinkPad Flex 5 (15)'s touchscreen IPS panel (AUO B156HAN02.five) has a Full HD resolution, comfortable viewing angles, skilful contrast ratio, and a not-flickering backlight. Although it is safe for long periods of employ, the panel has a relatively poor color representation, with only 50% of sRGB coverage, uneven luminance across the expanse of the screen, and colour accuracy, which is worse than beingness color-blind.

At least on the bright side, you get Wi-Fi 6 support, fast storage, an SD carte du jour reader on board, and decent battery life. And then, despite the fact that the laptop comes with a lot of features, including an optional Pen inside the box, the poor 1080p panel just won't deliver if you are hoping for something marginally shut to professional. However, Lenovo besides offers the Ideapad Flex v (15) with a 4K unit, which has HDR and VESA certificates. Additionally, one of the slap-up options on the marketplace is the ASUS ZenBook Flip fifteen (UX563).

Pros

Makes slap-up use of the Wacom drivers and its optional Digital Pen
Decent operation and battery life
4K IPS display option
Doesn't utilize PWM for whatsoever effulgence level (AUO B156HAN02.5)
Supports PCIe x4 SSDs, WiFi half-dozen standards, and SD cards

Cons

Lacks a Thunderbolt connector
No RAM upgradability mail service-buy
50% sRGB coverage (AUO B156HAN02.five)
Poor color accuracy (AUO B156HAN02.v)
Its base is a flake twisty
