Reset your Chromebook hardware

To fix some Chromebook problems, you might need to reset your Chromebook hardware, also called a hard reset.

Try a hard reset only after other ways to fix the problem have failed. It will restart your Chromebook hardware (like your keyboard and touchpad), and might delete some files in your Downloads folder.

For most Chromebooks, follow the steps below:

  • You can also press and hold Back  + Refresh  + Power  for at least 10 seconds.

  • On tablets: Press and hold the Volume Up and Power buttons for at least 10 seconds, then release them.
