Laptop Power Button Board: loose internal flex cable. The thin cable is not fully locked into its board connector.

The distinguishing clue

The device works intermittently after chassis movement.

Checks before an assessment

Record the button feel and any lights already observed after a normal press. Do not bridge contacts or press repeatedly when the button or case is damaged.

Stop point: Shorting random board pads to start a laptop can cause damage.

Workshop confirmation and repair

Device-level check: Compare charger and board power signs, then inspect the button, cable and connector with the battery isolated.

Targeted check: Inspect cable alignment and latch condition with the battery isolated. If confirmed: Reseat an undamaged cable or replace the cable and latch assembly.

Repair boundary: Replace the button board or cable only after standby power and motherboard response are confirmed.

Related cause to rule out

Checks after the work

After repair or replacement, check cold start, restart, shutdown, button feel and repeated presses.
