Lenovo ThinkPad P51 DESIGN
The ThinkPad P51 combines workstation-class general performance and graphics with a colorful display, durable design, wide port selection and all-day battery life. We wish that the laptop were lighter, that its screen were a bit brighter, and that we could access the power and Thunderbolt ports without reaching around to the back, but power-hungry users can easily deal with these trade-offs. If you’re looking for a more portable laptop and can settle for a Xeon E3-1505M instead of a 1535M, and for Nvidia Quadro M1200 graphics in lieu of an M2200 GPU, the Dell Precision 5520 is a great choice, because it weighs just 4.4 pounds and lasts nearly 12 hours on a charge. However, if you need all the performance you can squeeze out of a 15- inch mobile workstation; the ThinkPad P51 is a great choice. ThinkPad P51 can handle all of those demanding tasks and more thanks to gaudy components such as an optional Intel Xeon processor, an Nvidia Quadro M2200 GPU and a vibrant 4K display.
The ThinkPad P51 isn’t exactly the lightest laptop on the block, and, at 5.82 pounds and 1.02 inches thick. The P51’s power brick weighs 1.2 pounds all by itself. So, if you carry both the AC adapter and the laptop with you that are a full 7 pounds. The aesthetics on the P51 are all classic ThinkPad, and nothing stands out visually. It’s raven-black, with a matte finish on all of the surfaces except for the lid, which has a soft-touch texture. Though it feels like plastic, the bottom is made of magnesium and aluminum, and the lid is composed of glass-fiber-reinforced plastic.
Lenovo ThinkPad P51 DURABILITY AND SECURITY
The laptop has passed 11 different MIL-STD 810G durability tests, including those for humidity, vibrations, shocks and extreme temperatures. It also endured Lenovo’s own proprietary bump and stress tests.
There’s also a single-touch fingerprint reader for logging into the OS via Windows Hello.
Lenovo ThinkPad P51 DISPLAY AND AUDIO
The 15.6-inch screen gives good visual experience. Colors on the matte display stayed true but faded a bit at viewing angles wider than about 35 degrees. The ThinkPad P51’s 4K display can reproduce an impressive 172 percent of the sRGB color
Gamut, which is much more vibrant than the category
Average (126 percent). Lenovo includes a calibration sensor in the deck
And X-Rite Pantone software to use with it. After I launched the app, I was presented with the option to choose from among four white points: D50, D65, D75 and Native (aka,
normal). I also had the choice of three different tone response levels: 1.8, 2.0 and 2.2 (the default).
Lenovo’s Settings app allows you to choose from among four sound profiles: Music, Voice, Movies and Dynamic. While I noticed l little difference in quality among these
profiles, disabling the Dolby audio enhancement altogether made the music sound like it was coming from a mile away.
Lenovo ThinkPad P51 KEYBOARD, TRACKPOINT AND TOUCHPAD
The ThinkPad P51’s keyboard offers a good typing experience compared to most laptops, but it isn’t up to the standard I expect from a ThinkPad. The keys have a
Relatively deep 1.7 millimeters of travel and require a strong 68 grams of force to actuate. However, they felt a little stiffer and less responsive than those on other ThinkPads
Like almost every other ThinkPad, the P51 has two forms of navigation: a TrackPoint pointing stick and a touchpad. As on other models, the TrackPoint provided extremely precise movements, without forcing me to waste time and energy by moving my hands off of the home row.
Lenovo ThinkPad P51 PERFORMANCE
With its Intel Xeon E3-1535M v6 CPU, Nvidia Quadro M2200 graphics, 512GB PCIe SSD and 16GB of RAM, the ThinkPad P51 can handle everything thrown at it. Even with over a dozen tabs open and a 4K video playing, there won’t be a hint of lag.
On Geekbench 4, a synthetic benchmark that measures overall system speed, the ThinkPad P51 scored a strong 15,332, far better than the 12,861 desktop-replacement Category average.
Lenovo ThinkPad P51 GRAPHICS
The ThinkPad P51 is built for 4K video editing, 3D modeling and computer
Animation with its Nvidia Quadro M2200 GPU. Lenovo’s laptop got an impressive 228 fps on Dirt 3, which is nearly four times the category average (64 fps) and a little quicker than the ZBook 15’s mark (219 fps).
Lenovo ThinkPad P51 PORTS
The ThinkPad P51 has every port you need, but too many of them are located on the back. The right side contains a mini DisplayPort connector, two USB 3.0 ports, an audio jack and a Kensington lock slot.
The back surface has a Thunderbolt 3 port , Ethernet, HDMI out and two more USB 3.0 ports for a total of four. The left surface holds an SD card reader and the optional smart card reader.
Lenovo ThinkPad P51 BATTERY LIFE
Despite its large size, high-res screen and power-hungry components, the ThinkPad P51 offers all-day battery life. Lenovo’s notebook lasted a full 8 hours and 2 minutes on the LAPTOP battery test, which involves continuous surfing over Wi-Fi.
Lenovo ThinkPad P51 WEBCAM
The laptop’s 720p webcam can captured bright, colorful images.
Lenovo ThinkPad P51 SOFTWARE
The P51 comes preloaded with a handful of first-party utilities and the standard array of Windows 10 bloatware. Lenovo Settings gives you fine control over components like the Wi-Fi card, webcam and sound system, while Lenovo Companion checks for software updates. A relatively new utility that we haven’t seen on a ThinkPad before, Lenovo App Explorer is the company’s own app store, complete with a searchable database of software that you could probably have found on your own or seen in the Windows Store.
