A MacBook trackpad not working can be caused by simple connector issues—or swelling batteries pushing on the trackpad.
Common causes
- Swollen battery (very common on older models)
- Trackpad flex cable damage
- Trackpad failure
- Liquid damage on connectors
What to do
If your trackpad feels raised or hard to click, stop using it and get it checked—this may indicate battery swelling.
