Touchpad / Hotkeys issues
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.
3 Restart the Chrome OS by holding down the power button
until the device turns off, and then turn it back on again.
4 Try using the keys in the Guest account.
5 If users experience hotkey issues with the account that is not
the owner (primary) account, delete the user account and re-
create it.
6 If none of the above steps work, try to Reset or Recover the
Chomebook.
