The Lenovo ThinkPad T420s
Lenovo has unveiled six new ThinkPad laptops that it will offer to enterprise customers from March.
The T420s, T420, T520, L420, L520 and W520, shown off on Tuesday, are all based on Intel's new Sandy Bridge processors, which are marketed as being second-generation Core chips. Lenovo is promoting the models as providing "all-day battery life", enterprise management features, and video- and voice-calling capabilities, as well as power and performance boosts over earlier ThinkPads.
All models also conform to Lenovo's 'Enhanced Experience 2.0 for Windows 7', a certification that says the laptop can start up on average 20 seconds faster than a typical Windows 7 computer. All the models feature Nvidia's Optimus switchable graphics technology.
The T420s, pictured above, is an ultra-thin model that weighs 1.78kg. According to the company, it is also the first business-class notebook to feature Dolby Home Theater v4 sound.
Its 14-inch screen has an HD+ resolution of 1600 x 900 pixels, and it can use either Intel's on-board HD graphics or a discrete 1GB Nvidia NVS 4200M GPU. Like the other ThinkPads unveiled on Tuesday, the T420s has a 720p HD webcam.
The ThinkPad T420s will launch at the price of £1,099.
The Lenovo ThinkPad T420 and T420s
The 14-inch ThinkPad T420, pictured to the left of a T420s, comes with a particularly hefty claim from Lenovo — the company said it will run for up to 30 hours with the extended 'slice' battery.
Slice batteries are large extra batteries that fit onto the underside of the laptop. Lenovo bases its 30-hour claim on the combined use of the standard 9-cell battery and the 9-cell slice battery.
Both the T420 and its slightly larger sibling, the 15.6-inch T520, have display resolution options of 1366 x 768 pixels or 1600 x 900 pixels, while the larger model also comes with a full-HD 1920 x 1080-pixel resolution.
The T420 weighs 2.24kg and the T520 2.52kg. The T420 has a launch price of £845, as does the T520.
