Symptoms
- Chromebook behaves oddly across many apps
- Need to remove a previous owner's account
- Selling or giving away the device
- Repeated errors that other fixes didn't solve
Likely causes
- CommonSoftware corruption across profilesA powerwash reinstalls the OS cleanly, clearing issues normal troubleshooting can't reach.
- PossibleDevice managed by an old Google accountOld sync data or enterprise policies can linger until wiped.
What to do
- Back up any files stored locally in the Files app to Google Drive or a USB drive first; powerwash deletes them.
- Sign out of your Google account if you're currently signed in.
- Press and hold Ctrl+Alt+Shift+R at the sign-in screen, or go to Settings > Advanced > Reset settings > Powerwash.
- Click Restart, then confirm Powerwash when prompted.
- Wait for the device to reset and reboot; this takes a few minutes.
- Go through initial setup again and sign back into your Google account.
- Reinstall any Android or Linux apps you need since those are removed too.
Tools and parts
- USB drive for backup (optional)
When to call a pro
Not usually needed; a school or work-managed Chromebook may require an IT admin to remove enrollment before powerwash works fully.
