Touchpad / Hotkeys issues
Issue Possible solutions
Touchpad not responding
If the touch pad has stopped responding, try the following
steps to resolve the issue: Try moving the cursor after each
step:
1. Tap the Esc key several times.
2. Drumroll the fingers across the touch pad for a few
seconds.
3. Restart the Chrome OS by holding down the power button
until the device turns off, and then turn it back on again.
4. If the cursor still does not move when using the touch pad,
try logging in from the Guest account using the tab key to
navigate.
5. If users experience touch pad issues with the account
that is not the owner (primary) account, delete the user
account and re-create it. Again, use the tab key to
navigate.
6. If none of the above steps work, try to Reset or Recover
the Chomebook.
Top row of keys (Hotkeys) not responding
If a hotkey (like the volume or brightness keys) are not
responding, try the following troubleshooting steps, making
sure to test the keys after each one:
1. If the affected key is volume or brightness, check to make
sure you are not at the upper or lower limit for that
setting.
2. If the backward or forward buttons do not work, check
that the same icons in a web browser are not grayed out.
For example, if the back button on a web page is grayed,
this is because the browser is not aware of a page to move
backward to.
