The new Lenovo ThinkPad P1 Gen 7 is a Windows workstation laptop that comes with a variety of Nvidia GPUs and Intel Core Ultra CPUs. As the name suggests, it will replace the Lenovo ThinkPad P1 Gen 6 that was launched in 2023.
The design of the new ThinkPad P1 is a complete overhaul of the outgoing sixth-generation model and borrows some design elements from the ThinkPad Z16, such as the duralumin lid with camera bump and large tactile trackpad with virtual mouse buttons.
The result is a sleek, smart-looking laptop, and thinner screen bezels play a big role in this. It is made of aluminum-magnesium alloy and has a sturdy structure, just like an Iowa-class battleship. Without a doubt, this is one of the most rugged laptops ITPro has ever made. The P1 also meets the MIL-STD 810H standard for resistance to shock, particle intrusion, and extreme temperatures. You can charge the P1 using any Type-C portLenovo ThinkPad P1 Gen 7 laptop battery
. Our 100W PC charger worked fine, but the 65W charger popped up a “slow charger” alert. The 135W rat-tail DC charger that comes with the P1 with integrated graphics is smaller and lighter than the average charger, so it’s not a hassle to carry around. The 170WLenovo ThinkPad P1 Gen 7 laptop batterythat comes with the discrete GPU model is larger. Lenovo claims 60 minutes of 60W charging will get you to 80% charge, and we found that to be accurate. Wireless communications are at the forefront, with support for 6Ghz Wi-Fi 7 and Bluetooth 5.4 thanks to an Intel BE200 2×2 card. There hasn’t been a cellular modem option on the P1 for a while, and the new Gen 7 machine doesn’t reintroduce the feature. We think that’s a shame. Lenovo ThinkPad P1 Gen 7: Keyboard, touchpad and webcam The keyboard on the new P1 is very similar to the one on the ThinkPad Z16, which is to say there’s no number pad. Thankfully, all of the good things about the Z16 keyboard are retained, including the sturdy panel and crisp, precise key action. The keys have a standard 1.5mm of travel and smooth, perfectly damped end stops. The keyboard graphics and two-level backlighting are models of clarity. We’ve already conceded that money is no object, but the new ThinkPad has to earn five stars for its excellent design, impeccable build quality, impressiveLenovo ThinkPad P1 Gen 7 laptop battery life, and wide range of spec options.

Dynabook Portege X30L laptop batteryLifeDynabook is a fairly new name in the laptop world, but its roots run deep. The company was formerly part of Toshiba, which built its first laptop in 1985. Now Dynabook has branched out on its own, but it’s still producing laptops that stand out from the crowd because of their design, lightness, long battery life, and decent performance.
Dynabook Portege X30L Review: Performance and
Dynabook Portege X30L laptop battery
LifeThe X30L-K isn’t the fastest laptop on the market, but it’s got decent processing power. I found it had no problem running business apps, browsing the web, and streaming video, but it struggled a bit with video editing and gaming.
The Portege X30L-K may be a thin and light laptop, but when it comes to battery life, it’s definitely not thin and light. It lasted an impressive 13 hours and 2 minutes on the PC Mark 10 test, which plays a 1080P video until the Dynabook  laptop battery is dead. I also tested this laptop using PC Mark 10’s Modern Office test, which simulates someone working intensively on a spreadsheet and other common work tasks, and the battery life was about the same at just over 13 hours. That’s pretty impressive.
One thing to note is that I turned the screen brightness down to 200 Cd/M2 for both tests, two stops below minimum brightness. I did this for consistency so different laptops tested similarly. Turning the screen brightness up would undoubtedly shorten theDynabook Portege X30L laptop batterylife.
