Connecting the screen cable with the battery connected risks shorting the connector and poses a fire hazard.

Follow this step during reassembly to safely reconnect the screen and battery.

Prop up the bottom edge of the tablet on a box or similar object. Tilt the screen open and lean it against something so that it's angled up to 90 degrees.

Reconnect the small front sensor cable ZIF connector.

Reconnect the large screen cable ZIF connector.

Reconnect the battery press connector.

Use your Torx Plus 3IP driver to install the two 2.6 mm screws and fasten the connector cover.

Continue reassembly with these cables connected.
