Laptop Touchpad: 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

Compare an external mouse and note whether movement, clicking or gestures fail. A lifted touchpad or distorted palm rest may indicate battery swelling and must not be pressed down.

Stop point: A lifting touchpad can be the first visible sign of battery swelling.

Workshop confirmation and repair

Device-level check: Compare an external mouse, check settings and inspect for battery swelling beneath the palm rest.

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: Repair the cable or replace the correct touchpad after ruling out pressure from an unsafe battery.

Related cause to rule out

When pointer movement or clicks fails intermittently along a damaged touchpad cable path, also consider Laptop Touchpad: fractured flex-cable trace before choosing a repair.

Checks after the work

After repair or replacement, check movement, click zones, gestures, palm rejection and sleep recovery.
