Lenovo Thinkbook Plus Twist Gen 4 Convertible Review: E-ink And Oled Hybrid

The Lenovo ThinkBook Plus Gen 4, differently referred to as the ThinkBook Plus Twist, is now widely to be had after its preliminary unveiling at CES 2023. In spite of what its determine would possibly suggest, the ThinkBook Plus Gen 4 does indirectly trade the ThinkBook Plus Gen 3 on account of their vastly other design philosophies and display sizes. They do, on the other hand, percentage equivalent chassis fabrics and goal equivalent semi-professional customers who could also be grew to transform off at some stage in the consumer-centric IdeaPad collection or office-heavy ThinkPad collection.

Our unit in evaluate is a higher-end SKU with the Core i7-1355U CPU and built-in E Ink show for simply over $3000 USD. Lesser configurations include the Core i5-1335U and no E Ink show for $2800, then again all choices send with built-in graphics very best, 16 GB of soldered RAM, and a number one 13.3-inch 2.8K OLED touchscreen.

Festival come with different high-end convertible subnotebooks very similar to the Dell Latitude 9330, MSI Summit E14 Turn, Asus ZenBook Turn 14, or the HP Spectre 13.5 collection. If truth be told, none be offering E Ink touchscreen alternatives as our Lenovo.

Further Lenovo reviews:

In contrast to different ThinkBook fashions very similar to the ThinkBook 15 G3, the ThinkBook Plus Gen 4 makes use of extra steel than plastic for a further sumptuous actually in reality really feel that is further reflective of its excessive value vary. The bottom, for example, is noticeably further immune to twisting and creaking to be on par with the HP Spectre x360 13.5. The lid could also be rather company on account of it having two panes of glass reinforcement for the OLED and E Ink presentations in comparison to only one pane on maximum different laptops.

Excluding the 12-inch E Ink touchscreen at the outer lid, the twisting mechanism additionally is helping to tell apart the Lenovo type from maximum different convertibles to be had out there. The small hinge will also be was spherical 180 levels clockwise for pill mode after which 180 levels counterclockwise for pc mode to distinction the usual 360-degree hinges on usual convertibles. It actually works neatly from a mechanical perspective, then again the lid has a tendency to teeter further readily when in comparison to historically greater hinges. Confidently the original rotating hinge can last for numerous years of day by day abuse.

The twisting mechanism and secondary show upload just a little of thickness and weight when in comparison to usual 13-inch subnotebooks. The Dragonfly G4, for example, may be very on the subject of the equivalent measurement in all 3 dimensions then again it’s noticeably lighter by the use of 300 grams to be further travel-friendly. Thus, you will have to in truth definitely worth the distinctive alternatives of the ThinkBook Plus Gen 4 to justify the extra weight.

The type integrates simply two Thunderbolt 4 ports and a three.5 mm audio jack. The latter is notable as a couple of subnotebooks very similar to the ZenBook 13 will have to not have headphone jacks in the slightest degree. Be able to have adapters and docking stations ready will have to you plan on connecting USB-A or HDMI devices.

We recognize that there’s a USB-C port on each of the 2 facets of the computer that means you’ll be able to definitely worth the computer from both sides. That is by contrast to the Spectre x360 13.5 which is able to very best value by the use of its proper edge.

An Intel AX211 comes usual for Wi-Fi 6E and Bluetooth 5.2 reinforce. Switch charges are dependable and roughly sturdy when paired to our Asus AXE11000 6GHz check out router.

4G LTE or 5G choices are sadly now not supported since this isn’t a ThinkPad.

A 2 MP webcam with sliding shutter and IR come usual. Festival like HP have already begun supply laptops with 5 MP and even 8 MP sensors for sharper footage.

The ground panel is secured by the use of 8 T5 Torx screws for quite speedy servicing. Even so, there is not such a lot to support as very best the M.2 SSD and battery are simply detachable which is a now not peculiar belongings of convertible laptops.

The retail field features a Lenovo Virtual Pen 2 and AAAA battery along the standard paperwork and AC adapter. There are sadly no magnets at the pc for attaching or securing the stylus and so you will have to stay it for your pocket or bag for additonal secure supply.

A one-year restricted producer guaranty applies if bought in the united states.

The keyboard is a blended bag because it on the subject of feels adore it has taken a backseat to the presentations. Further specifically, the keys are spongier than we’re used to although in comparison to different IdeaPad fashions. The House secret is in particular irritating as its proper section would actually in reality really feel spongier than the left section when pressed. Throughout the meantime, the Input and Backspace keys are shallower than we would love. Lenovo is most often excellent on the subject of keyboards on ThinkPads and so it is a bit disappointing to appear them drop the ball at the ThinkBook Plus Gen 4.

The clickpad (10.5 x 7 cm) is greater than the only at the ThinkPad X1 Nano Gen 3 (10 x 5.6 cm) whilst being smaller than at the Dragonfly G4 (12 x 8 cm). It’s quite clicky when pressed for additonal delightful comments than the softer or spongier clickpads on maximum different laptops. Clatter is sharper and louder as a result, then again the trade-off is for sure for sure neatly definitely worth the clickier comments.

The principle touchscreen has the entire elementary qualities now now we’ve got come to be expecting from OLED in conjunction with extraordinarily speedy reaction instances, pitch perfect black ranges, and whole P3 colour protection. Perhaps crucial bitter spot of our panel is that its refresh value is restricted to simply 60 Hz. The Asus ZenBook and VivoBook collection have been supply with 90 Hz or 120 Hz OLED panels for some time now which actually in reality really feel right away smoother and additional responsive on the subject of navigation and touchscreen controls. Confidently such panels will become further widely to be had if Lenovo makes a decision to modify this type in the future.

There are two notable drawbacks to the E Ink show. To start with, its local solution is smaller than the main OLED show which creates issues when Area house home windows is switching between the 2 presentations. Your entire content material subject material topic subject material turns into resized and repositioned each time you turn presentations which you will have to then manually repair. A 1:1 solution ratio between the 2 presentations would have addressed this difficult factor.

The second one downside pertains to how clunky the E Ink touchscreen feels even after allowing for the gradual reaction instances. That is most most often on account of how unoptimized Area house home windows OS will also be for eReader functions. Automated rotation, for example, does not artwork reliably in eReader mode and the presentations would take numerous seconds to load when switching between the presentations. The transition section is as a result of this fact now not as clean or seamless as merely switching between pc and pill modes on same old convertible fashions with only one display.

The OLED show is decently calibrated in opposition to the P3 usual with inexpensive grayscale and colour deltaE values of two.7 and four.61, respectively. Graphics editors receive advantages essentially necessarily essentially the most from the deeper colours of OLED the place P3 colours don’t seem to be peculiar. Our calibrated ICM profile is to be had to acquire above without charge.

Pulse-width modulation is provide on all brightness ranges similar to on different OLED panels. We are able to file a frequency of 238 Hz from 0 to 57 % brightness and 60 Hz from 58 to 100% brightness.

Outside visibility is superb then again now not nice for an OLED panel. At about 350 nits most, the show is dimmer than some imaginable choices with IPS panels very similar to the MSI Summit E13 or Dell Latitude 9330 which is able to each reach 550 nits. Glare is as a result of this fact tricky to steer clear of until in case you are running below colour.

Then again, the E Ink show stays readable although below daylight. There could also be on the other hand just a little of glare given that glass overlay is not completely matte, then again it is minor and will also be simply lost sight of.

We set the unit to Efficiency mode by the use of Area house home windows and the Lenovo Vantage device previous to working the benchmarks beneath. We suggest turning into conscious about Vantage as it’s the hub for Lenovo-specific settings and power updates.

CPU efficiency is very best about 5 % slower than the usual pc in our database supplied with the equivalent Core i7-1355U CPU. The slight efficiency deficit will also be attributed to the restricted Turbo Spice up of the Lenovo as efficiency would dip by the use of as much as 18 % after the preliminary run of our CineBench R15 xT loop check out.

Downgrading to the Core i5-1335U configuration will very best impact CPU efficiency by the use of simply 10 to fifteen %. When you don’t seem to be searching for the graphics efficiency advantages of the Core i7-1355U, then it can be value taking into account the less expensive Core i5-1335U instead since it isn’t noticeably slower for now not peculiar utilization situations like internet surfing, inexpensive multi-tasking, or video streaming.

PCMark rankings are quite above maximum different laptops powered by the use of equivalent Intel Core-U collection CPUs. Subnotebooks powered by the use of AMD Zen 3+ or Zen 4 CPUs very similar to the Lenovo Yoga 7-14 or HP EliteBook 845 G10 usually typically generally tend to attain greater on account of their such a lot faster built-in GPUs when in comparison to our rising previous Iris Xe.

LatencyMon reveals minor-moderate DPC problems when opening a few browser tabs of our homepage. 4K video playback at 60 FPS is on the subject of perfect with simply 2 dropped frames everywhere a 60-second window.

Our check out unit ships with a high-end SK hynix PC801 PCIe4 x4 NVMe SSD which competes straight away with the most well liked Samsung PM9A1. Efficiency is superb and most be informed charges are sustainable at a excessive 6200 MB/s irrespective of the small and skinny shape issue of the ThinkBook Plus Gen 4.

The built-in Iris Xe 96 EUs is showing the place we think it to be relative to different laptops with the equivalent GPU if now not quite faster by the use of just a few share issues. Downgrading to the Core i5 SKU with the Iris Xe 80 EUs is predicted to lower graphics efficiency reasonably considerably by the use of about 30 to 35 % in line with our enjoy with the Lenovo ThinkPad X13 Yoga G4. Supply AMD imaginable choices very similar to the Radeon 680M or 780M are such a lot faster than any Intel iGPU answer on the time of writing.

Exterior GPUs are supported for faster efficiency. You are able to additionally technically run 3D video video video games at the E Ink show which is neat to appear then again differently impractical.

3DMark 11 rankings would stay quite equivalent between battery, Balanced, and Efficiency modes as showed at some stage in the desk beneath. Because of this that not unusual efficiency is impacted further at some stage in the restricted Turbo Spice up spice up of the device reasonably than the prevailing profile environment.

Fan noise is solely noticeable everywhere now not peculiar such a lot like internet surfing, studying, or video streaming the place it hovers round 27 dB(A) in opposition to a silent background of 24.3 dB(A). Upper such a lot like 3DMark 06 or would build up fan noise to a further noticeable 38 dB(A) very similar to what we noticed at the Latitude 9330.

We are able to file a most fan noise of fairly beneath 42 dB(A) when working video video video games or different intense such a lot for prolonged categories. The low 40 dB(A) vary is usual of extreme convertibles and laptops powered by the use of U-series CPUs.

Ground temperatures are cooler than anticipated at the keyboard aspect whilst the bottom can get such a lot hotter. Sizzling spots at the keyboard very best reach round 30 C in comparison to 39 C at the backside. The heat is noticeable then again not at all distracting on pc or pill modes.

When working Prime95, CPU clock charges and package deal deal energy draw would spike to a couple of.3 GHz and 54 W, respectively, and at a excessive core temperature of 97 C. This is in a position to last for very best 10 to fifteen seconds ahead of clock charges and board energy draw would fall to simply 2.4 GHz and 26 W so that you could care for a cooler core temperature of 75 C. Turbo Spice up imaginable is thus restricted to simply numerous seconds at maximum which isn’t abnormal on Core U-series subnotebooks.

GPU clock charges and temperature when working Witcher 3 would stabilize at 1297 MHz and 71 C, respectively, in comparison to 69 C at the Intel-powered Dragonfly G4.

Energy intake when idling on desktop is set 7 to eight W, then again it may be as excessive as 13 W when showing content material subject material topic subject material this is most most often white in colour related to nearly all of internet pages on account of the OLED touchscreen. Compared, different subnotebooks with same old IPS panels very similar to the ThinkPad X1 Nano Gen 3 or Dragonfly G4 would draw on the subject of section as such a lot energy although on their most brightness settings.

When working heavier such a lot, intake can be a lot nearer to what now now we’ve got come to be expecting from a Core U-series pocket e ebook. In truth, the entire intake vary can be similar to what we recorded at the ZenBook S 13 OLED or Dragonfly G4.

We are able to measure a most intake of 66 W from the small (~5.5 x 5.5 x 2.8 cm) 65 W USB-C adapter when the CPU is at 100% usage. This value would very best last for 10 to fifteen seconds as showed at some stage in the screenshots beneath on account of the thermal obstacles of the kind.

Battery capability is quite greater than at the ThinkPad X1 Nano Gen 3 to compensate for our further difficult OLED touchscreen. WLAN runtime is as a result of this fact on the subject of the equivalent between the 2 fashions at roughly 8 hours. Competing methods very similar to the Latitude 9330 or HP Dragonfly G4 can last for one or two hours longer a minimum of.

Battery life when studying on E Ink mode lasts for longer at about 12 hours.

Charging from empty to complete capability takes about 80 mins although Lenovo Speedy Price is enabled.

When you like to hold each a computer and an eReader with you at all times, then the ThinkBook Plus Gen 4 was once as soon as made for you. The E Ink display works reasonably neatly below Area house home windows 11 and it does not negatively impact the standard of the remainder of the kind. In truth, the lid and base are more potent than anticipated on account of the extra steel and glass.

There could also be indubitably room for growth. The gradual transition and constant resizing of space house home windows when switching between the 2 presentations actually in reality really feel clunky in practice although the presentations themselves are of top-end. Throughout the meantime, automated rotation is unreliable as its orientation is incessantly incorrect most likely on account of the original twisting mechanic of the kind.

Perhaps crucial asterisk to bear in mind is that the ThinkBook Plus Gen 4 is considerably heavier than any same old eReader which may make dealing with tricky in eReader mode. You will have to in truth artwork across the weight will have to you cherish to do numerous studying in mattress or at the bus.

The ThinkBook Plus Gen 4 works neatly as a normal convertible, then again it is eReader capability is hindered by the use of clunky device and a quite heavy weight when in comparison to standalone eReaders.

If you do not definitely worth the E Ink show, then imaginable choices very similar to the Dell XPS 13 2-in-1 or LG Gram 14 2-in-1 are noticeably lighter and with longer battery life or further built-in ports. There is not any denying that the E Ink display provides tangible weight and thickness to the design of the ThinkBook Plus Gen 4 even supposing configured with out the characteristic.

Lenovo is now supply the ThinkBook Plus Gen 4 beginning at $2800 USD for the Core i5 non-E Ink configuration as much as $3000 for the Core i7 E Ink configuration.
