The Lenovo x131e is a rugged low-end laptop originally released on July 31 2012, for schools and businesses. It came in a wide variety of skews ranging from AMD E series CPUs to Intel Celerons and low-class i3 processors. It was re-released as a Chromebook in 2013, despite no changes to hardware. A board view is available online for this device, though at the time of writing the author is unsure of its accuracy.

The laptop has a removable battery held in by two latches at the bottom. One is spring loaded, The other is a toggle. The battery simply slides out.

Some versions of the x131e were equipped with SIM slots. Removing the battery and lifting the small rubber plate in the center of the battery compartment allows access to the slot.

Two P1 screws hold in the sled to the chassis. the assembly slides a little to the left, disconnecting itself, and then up and out to remove the drive. A plastic tab is installed on the drive to assist in removing the drive and sled assembly. Two more P1 screws fasten the sled to the drive.

Misc. Issues[edit | edit source]
Wobbly Feet[edit | edit source]
The feet on the plate at the bottom of the laptop may cave in, causing the laptop to become wobbly. the cause of this is that the piece of plastic attached to the chassis where the feet are on the plate has broken and fallen into the laptop. It may be possible to glue the piece back into place, but my solution was to fold up a fraction of paper and place it where the part should be. Whatever your solution, make sure that it is non-conductive, as components lie directly underneath the piece, or where the piece used to be.
