Laptop Touchpad: fractured flex-cable trace. Repeated bending breaks one or more conductors.

The distinguishing clue

Pointer movement or clicks fails intermittently along a damaged touchpad cable path.

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

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

Related cause to rule out

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

Checks after the work

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