Laptop Power Button Board: fractured flex-cable trace. Repeated bending breaks one or more conductors.

The distinguishing clue

Button response fails intermittently along a damaged power button cable path.

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: Compare the failure pattern and check continuity without puncturing the cable. If confirmed: Replace the damaged flex or complete input module.

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

Related cause to rule out

When the device works intermittently after chassis movement, also consider Laptop Power Button Board: loose internal flex cable before choosing a repair.

Checks after the work

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