Background
The Lenovo ThinkPad X240 is a 2013 release apart of Lenovo's X series which began in 2000. Lenovo aimed toward building laptops with decent batteries, good business performance, and to be durable. This laptop was built with a small frame and light material for portability.
The X240 has a built-in, non-removable 3-cell battery and comes with a removable 3-cell and 6-cell battery, both of which are hot-swappable, which allows you to replace a spent battery with a charged battery without powering down the notebook. The X240 is the first X series laptop to forgo the classic trackpoint buttons in favour of a touchpad that can also be pushed.
Identification
You can find the model type and serial number printed on the bottom of the Lenovo ThinkPad X240 or under the battery.
