Lenovo T410 Power-On Without Keyboard

Technicians often need a T410 to power on with the palmrest off. Knowing the board power pads/button cable location beats reassembling blindly every test.

Bench tips

• Use the external board power pads/button cable per hardware maintenance manual.
• Keep the CMOS battery connected for fewer POST surprises.
• Support the board—no shorts on screw posts.

Safety notes

Remove the main battery and AC when seating cable connectors; T410 boards are unforgiving of backwards keyboard flexes.
