Symptoms
- Cursor doesn't move when touching the trackpad
- Trackpad works but clicks/taps don't register

Likely causes
- CommonTrackpad accidentally disabledA function key shortcut or setting can disable the trackpad, especially when an external mouse is plugged in.
- CommonOutdated or corrupted trackpad driverDriver issues after a system update are a frequent cause of trackpad misbehavior.
- CommonSoftware glitch requiring a restartA temporary system glitch can freeze input from the trackpad without affecting anything else.
- PossibleDirt, moisture, or a case interfering with the surfaceA dirty or damp surface can cause erratic or missed touches.
- Less commonPhysical or internal hardware damageA drop or spill can damage the trackpad's internal connector.
What to do
- Check for a dedicated function key (often F5-F9 with a trackpad icon) that toggles the trackpad on and off.
- Restart the laptop, since this clears many temporary input glitches.
- Check whether an external mouse is connected; some laptops auto-disable the trackpad when a mouse is plugged in.
- In Settings, search for Touchpad settings and confirm it's enabled, then adjust sensitivity if it's jumpy.
- Update the trackpad driver via Device Manager (Windows) or check for a macOS software update.
- Wipe the trackpad surface clean with a dry, lint-free cloth and dry your hands before testing again.
- If the trackpad remains unresponsive after these steps, it may need a professional hardware check.

When to call a pro
If the trackpad stays dead after driver updates and a restart, and there's no obvious disable switch involved, a technician should check the internal ribbon connector.
