The ThinkPad L sequence provides entry-level and mid-range industry notebooks at an inexpensive worth. The least pricey fashions of this 15.6-inch pocket book price about $900. Lenovo sells variations with each AMD and Intel internals, and this style is AMD-based. The ThinkPad L14 Gen 4 is a 14-inch style that we simply evaluated.
The Acer Aspire Vero AV15-53P, Schenker VIA 15 Professional M22, HP ProBook 445 G10, Fujitsu LifeBook E5412A, and Dell Latitude 3440 are a number of the competition. This similarity applies extra strongly to the final 3 laptops’ respective 15.6-inch sister variations.
The case, characterised through its sober and useful design, is crafted from black plastic. Extra delicate casing fabrics are reserved for the upper ThinkPad sequence. The long-lasting ‘ThinkPad’ lettering is prominently displayed at the again of the lid and the palm relaxation, each that includes delicate, matte surfaces. Particularly, there’s no repairs flap; then again, the battery (screwed, no longer glued) and different internals are obtainable after disposing of the ground shell. A good function is that the waste warmth is dissipated at the proper facet of the pocket book, making sure enough cooling even if the lid is closed, as an example, when docked.
The software shows no noticeable processing flaws, and the distance dimensions are right kind. Whilst the bottom unit will also be twisted somewhat an excessive amount of, higher tension could be fascinating. The lid stays inside of cheap limits. Making use of force to the again of the lid does no longer lead to symbol adjustments, and the tight hinges securely dangle the lid in place. The utmost opening attitude is 180 levels, and one-handed opening is imaginable.
Inside the comparability box, the ThinkPad will be the heaviest pocket book, weighing round 4.188 lbs. In the case of dimensions, the 15.6-inch units within the check box don’t percentage many similarities. The 14-inch competition, in fact, are a lot more compact and lighter.
The pocket book is provided with two USB-A ports (USB 3.2 Gen 1) and two USB-C ports (USB 3.2 Gen 2). Particularly, the USB-C ports improve Energy Supply and DisplayPort capability. Together with the HDMI slot, the pc boasts as much as 3 video outputs. Moreover, it includes a mixed audio socket, Gigabit Ethernet, and an not obligatory SmartCard reader to spherical off its connectivity choices.
The microSD reminiscence card reader, examined with the AV Professional SD microSD 128 GB V60 reference card, falls inside the class of medium-fast fashions. It demonstrates switch charges of 55.9 MB/s all the way through the switch of 250 JPG symbol information, each and every 5 MB in dimension, and achieves 88.9 MB/s when copying huge information blocks.
Below optimum stipulations—akin to no WiFi units within the fast neighborhood and a brief distance between the pc and the server PC—superb WiFi information charges are accomplished. The L15 is provided with a WiFi 6E chip (Mediatek MT7922). For stressed connections, it includes a controller (RTL8168/8111; 1 GBit/s) from Realtek.
Along with WiFi, wi-fi connections will also be established by way of the LTE community, due to the inclusion of a corresponding modem (Quectel EM05-G; CAT 4, max. 150 MBit/s obtain, 50 MBit/s add). The SIM card reader (nano-SIM) is situated at the again of the pc, and eSIM could also be supported
In the case of high quality, the webcam (2.1 MP + IR, max. 1,920 x 1,080 pixels) supplies same old efficiency. Then again, a colour deviation of roughly 12 (with the objective being DeltaE < 3) is a bit of upper than desired. On a favorable be aware, the digital camera includes a mechanical duvet, improving privateness and safety.
The pc provides get admission to safety thru fingerprint reputation, Home windows Hi, or SmartCard authentication. Moreover, it includes a Relied on Platform Module (2.0) for enhanced safety. For bodily safety, the software will also be secured the usage of a cable lock.
But even so the usual paperwork (guaranty data, fast get started poster), no further equipment are integrated with the TP.
After loosening the beneath screws, the bottom plate will also be got rid of with a flat spatula. This gives get admission to to more than a few elements, together with the SSD (PCIe 4 SSD in PCIe 3 slot, M.2-2242), the WLAN module, the LTE modem, the reminiscence banks, the battery, the audio system, the fan, and the BIOS battery.
Lenovo grants the ThinkPad a one-year guaranty inside of the United States.
Lenovo equips the ThinkPad with a backlit (two-level) chiclet keyboard, which incorporates a quantity pad. The sleek, concave keys be offering a brief and transparent stroke. Whilst the important thing resistance is appropriate, some customers would possibly want a crisper really feel. It is price noting that the keyboard has a slight leap when typing. One inconvenience is the swapped positions of the FN key and the left CTRL key, requiring customers to regulate their practiced hand actions. In spite of this, Lenovo delivers an excellent keyboard general, well-suited for on a regular basis use.
A click on pad, measuring roughly 4.52 x 2.20 inches, serves as the main mouse substitute with a brief stroke and a transparent force level. The trackpoint, additionally to be had, lets in for extra exact keep watch over of the mouse pointer. The 3 smooth-running mouse buttons accompanying it supply a transparent force level.
Lenovo equips the ThinkPad L15 G4 with a matte, viewing-angle-stable 15.6-inch show (1,920 x 1,080 pixels) in a 16:9 layout. Particularly, there’s no PWM flickering, and the show boasts a moderately top distinction. The brightness falls somewhat beneath the objective (> 300 cd/m²). However, the ThinkPad is to be had with a somewhat brighter FHD touchscreen. There are not any different show choices.
The show has an appropriate colour illustration out of the field; then again, with a deviation of round 6.2, it falls wanting the objective (DeltaE < 3). Calibration brings the worth right down to 4.2, leading to a extra even show of the grayscale.
The panel isn’t in a position to reproducing the AdobeRGB (43%), sRGB (63%), and DCI-P3 (42%) colour areas. In consequence, it might not be appropriate for software eventualities that call for top colour constancy, as some competition be offering higher efficiency on this regard.
The viewing-angle-stable IPS panel lets in clarity from any place. Moreover, it’s possible to learn the display screen outdoor, only if the daylight isn’t too vivid.
Inside the ThinkPad L15 G4 sequence, Lenovo provides fashions with APUs from AMD (Ryzen 7000) in addition to CPUs from Intel (Raptor Lake). On this evaluate, we center of attention on an AMD-based style. The AMD fashions to be had on the time of trying out vary in worth from $900 to $1,300.
Fairly than the usage of its personal power profiles, Lenovo employs Home windows profiles, known as power statuses (see desk). The supplied efficiency ranges range relying at the decided on standing. For benchmarks and runtime load, the ‘Very best efficiency’ profile was once used, whilst the ‘Balanced’ profile was once hired for different runtime assessments.
The Ryzen 7 PRO 7730U APU, a part of the Barcelo sequence and according to Zen 3 structure, options 8 CPU cores with a complete of 16 threads, achieving a most clock charge of four.55 GHz for a unmarried core. Below steady multi-thread load, as seen within the CB15 loop, the CPU maintains a persistently top Turbo clock.
Whilst efficiency is influenced through the power profile in use, variations between profiles don’t seem to be considerable. The one-thread efficiency, which is extra related for on a regular basis use, persistently stays at a top point.
Benchmark effects, in comparison with the non-“PRO” variant Ryzen 7 7730U APU, point out that the existing APU values are at a median point below the ‘Very best efficiency’ profile. The ‘PRO’ designation indicates improve for AMD PRO applied sciences, encompassing a selection of safety purposes adapted for industry use.
The easily running machine is optimized for workplace and Web packages, in addition to frugal video games at low settings. One of the crucial computing energy stays untapped, because the RAM (16 GB, DDR4-3200) operates handiest in single-channel mode. Putting in a 2d reminiscence module would treatment this, activating dual-channel mode for enhanced efficiency.
The standardized latency track check, encompassing internet browsing, 4k video playback, and Prime95 Prime-Load, exposed anomalies. The machine does no longer appear well-suited for real-time video and audio modifying. It is price noting that long term device updates may just probably convey enhancements and even deteriorations to the efficiency.
The machine pressure is a 512 GB SSD (PCIe 4, M.2-2242) from SK Hynix, handing over general just right information charges. Being put in in a PCIe 3 slot, it falls wanting its complete doable. A good be aware is the absence of thermally triggered throttling. You must spotlight that handiest SSDs within the M.2-2242 layout have compatibility, apart from the extra not unusual M.2-2280 fashions. Sadly, the L15 does no longer supply area for extra SSDs.
The built-in Vega 8 iGPU is located within the mid-range of AMD’s present lineup, that includes 512 shaders, DirectX 12 improve, and a most clock charge of two,000 MHz. Impressively, the latter will also be maintained completely, as demonstrated within the Witcher 3 check. The benchmark effects are some distance beneath reasonable because of the running reminiscence working in single-channel mode. An important efficiency spice up may well be accomplished through putting in a 2d reminiscence module, activating dual-channel mode (see diagram).
Whilst the computing energy of the integrated APU meets the necessities of many undemanding video games at low settings, it’s worthwhile to be aware that the ThinkPad isn’t designed as a gaming pocket book. The rather low body charges seen will also be attributed to the RAM running in single-channel mode. Particularly, vital efficiency enhancements may well be accomplished through putting in a 2d reminiscence module, thereby activating dual-channel mode (see diagram).
To evaluate the stableness of body charges over a longer duration, we carried out a 60-minute check working the sport ‘The Witcher 3’ at Complete HD answer with most high quality settings. The in-game personality remained desk bound, and no noticeable drop in body charges was once seen.
The ThinkPad maintains a remarkably low noise point throughout its complete load vary. The fan continuously stays desk bound or operates at low speeds. Below the ‘Very best efficiency’ power profile, the utmost sound force point reaches 32.7 dB(A) below complete load—a worth that many notebooks don’t even achieve below low load.
A pity: an digital spluttering noise will also be heard from throughout the casing when the SSD is closely accessed.
Total, the pc stories handiest slight heating. The Witcher 3 check registers a selective most price of 113 °F. In on a regular basis use, the temperature values stay with ease inside the inexperienced vary.
The tension check, involving the continual operation of Prime95 and Furmark, items an excessive state of affairs for trying out machine steadiness below complete load. In the beginning of the check, the CPU operates at clock charges of three.4 to three.6 GHz, step by step reducing to three to three.1 GHz because the check progresses. Concurrently, the GPU clock charge stories a drop from 2 GHz to one.4 GHz after a little while and stays at this decrease point.
The stereo audio system produce respectable sound, albeit with minimum bass.
The ability intake aligns with the anticipated point for the put in {hardware}. All the way through the Witcher 3 check with consistent energy intake, there’s a noticeable drop in call for seen within the pressure check. The provided energy provide unit (65 watts) is sufficiently dimensioned for the machine.
In line with the information sheet, Lenovo supplies 3 battery possible choices for the ThinkPad (46.5 Wh, 57 Wh, and 63 Wh), with the center sort being applied all the way through this check. Thus, the 15.6-inch pill achieves extraordinarily just right precise runtimes of eleven:56 hours (WiFi; surfing web sites by way of a script) and 9:29 hours (video; brief movie Giant Greenback Bunny, H.264 encoding, FHD).
The mix of the Ryzen 7 PRO 7730U and 16 GB RAM (single-channel mode) adeptly handles workplace, web packages, and frugal video games. We suggest putting in a 2d reminiscence module to totally unharness the APU’s doable, in particular reaping benefits graphics efficiency.
Lenovo’s presentation of the ThinkPad L15 Gen 4 (AMD) introduces a well-rounded mid-range industry pocket book with some minor weaknesses.
Its compact design, reasonable weight (roughly 4.18 lbs), and superb runtimes make the L15 a extremely cellular pc. The presence of 2 USB-C ports (USB 3.2 Gen 2) for energy provide and seamless integration into current workstation setups is a notable function. Moreover, low emission values and the inclusion of an LTE modem give a contribution definitely.
Then again, the integrated FHD display screen (IPS, 15.6-inch) falls brief in colour area protection, and the brightness stays beneath the objective (> 300 cd/m²). In spite of those drawbacks, the show boasts beneficiant distinction and a matte floor. Complaint is directed against the one-year guaranty, which is predicted to be extra powerful for a pocket book on this worth vary.
As an alternative choice to the L15, the Acer Aspire Vero AV15 items itself. It includes a brighter, extra colourful (sRGB) FHD show, two Thunderbolt 4 ports, and a QHD webcam. It does include trade-offs, such because the absence of a Gigabit Ethernet slot and a reminiscence card reader. Moreover, the RAM is onboard, which means it can’t be changed or expanded.
The Lenovo ThinkPad L15 Gen 4 (AMD) is priced at $1,300 on Amazon.
