Welcome to a laptop battery specialist
of the Lenovo Laptop Battery
You won't want to move this mammoth workstation around very often, but Lenovo's ThinkPad W550s is still the best overall notebook in its category. It has everything professionals could want in a 15.5-inch laptop, including a top-notch keyboard, durable design and epic battery life. It's heavier than competing machines, and not quite as quick as some, but those are fair trade-offs for a work machine this well-rounded.
The W550s doesn't stray from Lenovo's tried-and-true ThinkPad design scheme. The new device sports the same no-nonsense, matte-black plastic body as other laptops in the line. Most importantly, it looks right at home in a conference room.
This is a notebook you'll want to leave at your desktop with battery like Lenovo FRU 92P1182 Battery, Lenovo 3000 C100 Battery, Lenovo 40Y8313 Battery, Lenovo 121000929 Battery, Lenovo 57Y6632 Battery, Lenovo L09S3Z14 Battery, Lenovo IdeaPad S100 Battery, Lenovo IdeaPad U165 Battery, Lenovo IdeaPad U150 Battery, Lenovo 57Y6460 Battery, Lenovo ThinkPad Edge E10 Battery, Lenovo ThinkPad X100e Batterymost of the time with , though. Weighing in at 5.47 lbs., the ThinkPad W550s feels distinctly heavier than competing machines like HP's ZBook 15u G2 (4.23 lbs.) and the MSI WS60 (4.36 lbs.) On the bright side, Lenovo managed to shave about 0.33 lbs. off from the weight of last year's ThinkPad W540, which tipped the scales at a whopping 5.8 lbs.
The new machine's frame is reinforced with carbon fiber, which makes the whole unit feel extremely rigid and durable. Lenovo also says that the W550s is rated to withstand shock, extreme temperatures and high accelerations. Finally, the keyboard has a protective layer beneath the keys that directs spilled liquid to drain out the bottom of the machine, which is a crucial bit of extra protection for workers who depend on their laptops for work every day.
The big, 5.5-inch display on the ThinkPad W550s gives you tons of room to work, with a supersharp resolution of 2,880 x 1,620 pixels. Text is crisp, and colors are generally accurate, but the matte finish on the display makes everything look a bit washed out. On the bright side, the matte screen does a pretty good job of deflecting annoying reflections from overhead office lights.
My review unit came with a touch screen, but I'd recommend opting for the nontouch version. That's because the touch panel is heavy and expensive, without adding much useful functionality.
Typing on the ThinkPad W550s feels almost like typing on a desktop keyboard, thanks to its deep key travel and good feedback. The keys offer about 2.3mm of travel, which is well above the laptop average of 1.5mm, resulting in a supremely comfortable typing experience.
Business users will benefit from the inclusion of a full 10-key number pad, to the right of the standard QWERTY layout. That's a really nice perk if number crunching is part of your daily workload. Lenovo stuck a few handy shortcut keys above the number pad, giving you quick access to the calculator, Web browser and other tools.
I like that the function keys at the top of the keyboard default are automatically set to perform actions like adjusting the brightness and volume, as well as toggling the keyboard backlight on and off. That last feature is nice for typing in low-light environments.
If I have a complaint, it concerns Lenovo's annoying habit of repositioning the left Control key to make room for the Fn function key in the keyboard's bottom left spot. It really messes up my muscle memory for keyboard shortcuts like cutting and pasting text.
