Symptoms
- Cursor doesn't move at all when touching the trackpad
- Trackpad worked before and stopped suddenly
- External mouse works fine, ruling out a broader system issue
- Trackpad may have a small light indicating it's toggled off
Likely causes
- CommonTrackpad accidentally disabled via a function-key shortcutMany laptops have a dedicated key or key combination to toggle the trackpad on/off.
- CommonTrackpad driver crashed or was disabled in settingsA driver issue can leave the trackpad completely inactive.
- CommonTrackpad automatically disabled because an external mouse is connectedSome laptops have a setting to disable the trackpad whenever a mouse is plugged in or paired.
- PossibleInternal ribbon cable connection issueMore likely after the laptop was dropped or recently opened for service.
What to do
- Look for a trackpad toggle key (often near the top row, sometimes combined with Fn) and press it to see if the trackpad reactivates.
- Check trackpad settings to confirm it isn't disabled, especially any 'disable when mouse connected' option, and disconnect any mouse to test.
- Update or reinstall the trackpad driver from Device Manager or the manufacturer's site.
- Restart the laptop fully to rule out a temporary glitch.
- If available, boot into BIOS/UEFI setup and see if the trackpad functions there, which can indicate a driver versus hardware issue.
- If nothing restores it and there's no toggle or setting involved, this may need a technician to check the internal connector.
Tools and parts
- External mouse (for testing)

When to call a pro
If the trackpad also doesn't respond in BIOS/UEFI setup, this points to a hardware or connector issue that a technician should check.
