Quick Answer
An unresponsive ASUS Chromebook trackpad is almost always software: a frozen input driver, a setting that got disabled, or interference from an external mouse. A restart combined with checking the trackpad toggle in Settings fixes the vast majority of cases without any hardware work.
Causes
- Trackpad accidentally disabled — ChromeOS lets you turn off the trackpad entirely, which is easy to trigger by accident in Settings.
- External mouse connected — some ASUS models suppress the trackpad while a USB or Bluetooth mouse is active.
- Frozen input driver — a background process can hang and stop responding to trackpad input specifically, while the rest of the system works fine.
- Moisture or residue on the surface — a damp or greasy trackpad surface causes jumpy or ghost input.
- Physical damage — a worn ribbon cable or cracked trackpad surface from a drop, usually paired with visible physical signs.
How to Fix It
1. Restart the Chromebook
This clears a frozen input driver, which is the single most common cause of a trackpad that stopped responding out of nowhere.
2. Check the trackpad toggle in Settings
Go to Settings > Device > Touchpad and confirm the touchpad is enabled. It’s a single switch, and it’s the most overlooked fix because the trackpad still looks physically fine when it’s toggled off.
3. Disconnect any external mouse
Unplug any USB mouse and turn off Bluetooth peripherals, then test the trackpad again. Some ASUS Chromebook models automatically defer to a connected mouse and ignore trackpad input while one is active.
4. Clean the trackpad surface
Power off the Chromebook and wipe the trackpad with a slightly damp microfiber cloth, then dry it fully before turning the device back on. Residue from food, lotion, or sweat is a common cause of jumpy or erratic cursor movement.
5. Adjust sensitivity settings
In Settings > Device > Touchpad, try adjusting the speed slider and toggling “Tap-to-click” off and back on. A corrupted setting here can make the trackpad feel unresponsive even though it’s technically working.
6. Powerwash if the issue persists
⚠ This erases local data (files not backed up to Google Drive). A Powerwash resets all input driver settings from scratch and resolves persistent software-level trackpad issues that survive a normal restart.
Still Not Fixed?
If the trackpad remains completely dead after a Powerwash, or if you notice a section of the surface that doesn’t register touch at all while the rest works, this points to a physical fault — either a disconnected ribbon cable or a cracked trackpad module. At that point, replacement is the only fix; see our trackpad replacement guide for cost and what’s involved.
FAQ
Why does my ASUS trackpad work sometimes but not others?
Intermittent response usually points to a software conflict rather than hardware — try the driver reset (restart) and sensitivity reset above before assuming a physical fault.
Can I just use a USB mouse instead of fixing it?
Yes, as a workaround, but it won’t fix the underlying cause. If the trackpad is under warranty, it’s worth diagnosing properly rather than living with an external mouse permanently.
Does cleaning the trackpad risk damaging it?
Not if you power off the device first and use a barely damp cloth — avoid spraying liquid directly onto the surface or letting moisture reach the edges.
