Review: Lenovo ThinkPad X220t
November 28, 2011
In February 2011, Lenovo announced the ThinkPad X220t 12.5-inch Tablet PC, which is based on Intel's Sandy Bridge notebook platform. The ThinkPad X220t supplants the ThinkPad X201t and is a significant update.
Design and Changes
The ThinkPad X220t retains much of the same basic design of the previous generation ThinkPad X201t 12.1-inch Tablet PC. A ThinkPad X220t with a multi-touch display weighs approximately 4.1 pounds with a travel weight (which includes power adapter) of about 5.0 pounds.
Information System & Computing (ISC) believes that the biggest change in the X220t is the transition to a 16:9 LED-backlit display. The X220t's only display resolution choice is 1366 x 768, giving a resolution of 125 ppi.The most visible change for the ThinkPad X220t is a yellow-colored USB port. This port is always-on; it remains active even when the ThinkPad is in a suspend/hibernate state to allow charging of smartphones or other USB powered accessories. The X220t uses the same power supplies and Series 3 docking solutions that the ThinkPad X201t uses.
The ThinkPad X220t is optimized for videoconferencing with dual noise cancelling microphones, low light sensitive cameras with auto white balancing, and a lit microphone mute switch on the keyboard.
Several notes when ordering a ThinkPad X220t:
See ISC's Notebook Purchasing Guide for more configuration hints. As of November 2011, configuring a ThinkPad X220t to the Tablet PC specification can be done for approximately $1,700. The University's Computer Connection has a X220t configuration available for order.
ISC tested a ThinkPad X220t with 2.5 GHz Core i5, 1067 MHz 4.0 GB RAM, integrated Intel HD 3000 graphics, 128 GB solid state drive, and Windows 7 Professional 64-bit. It received a Windows Experience Index base score of 4.8, with individual scores of:
These scores suggest that Windows 7 performance will be excellent for most users on a ThinkPad X220t configured in this manner.
ISC sees the ThinkPad X220t as one of the best (if not the best) Tablet PCs available in late 2011.
When correctly configured to the Tablet PC specification in the Notebook Purchasing Guide, the ThinkPad X220t is approved for use at the University.
