If your Chromebook won't turn on...

If your Chromebook won't turn on, try a hard reset by holding the power button and refresh key (usually the one with a circular arrow) for a few seconds. 

If that doesn't work, disconnect the charger and peripherals, hold the power button for 15-30 seconds, then reconnect the charger and try again.

If your Chromebook screen is frozen...

If your Chromebook screen is frozen, a hard reset can often fix the issue. Hold down the Refresh button and the Power button at the same time for about 10 seconds. If the screen remains blank, try holding the Power button down until the screen goes black, then release and press it again. 

Here's a more detailed breakdown:

1. Try a Hard Reset:

Locate the Refresh (circular arrow) button on your Chromebook keyboard. 

Press and hold the Refresh button and the Power button simultaneously for about 10 seconds. 

If the screen remains black after the 10 seconds, release both buttons and then press the Power button again to turn the Chromebook back on. 

2. If the Hard Reset Doesn't Work:

If the Chromebook doesn't respond to the hard reset, try holding the Power button down until the screen goes completely black.

Release the Power button and then press it again to power the Chromebook back on. 

3. Additional Troubleshooting:

Unplug External Devices: Disconnect any external devices like USB drives or headphones. 

Check for Updates: Ensure your Chromebook is running the latest version of Chrome OS. 

Use Chrome Task Manager: If the Chromebook is slow but not completely frozen, try using Chrome's Task Manager to force-close unresponsive apps. 

Powerwash: If other methods fail, you can try a powerwash, which resets the Chromebook to factory settings, says the Google Help Center. 

4. When to Seek Further Help:

If the Chromebook continues to freeze or if you suspect a hardware issue, contact your Chromebook manufacturer for assistance.
