If your issue is a broken screen, your battery is not charging, or your Chromebook is just "plain dead", skip ahead to step 3.
Many problems can be resolved by following the Chromebook Clean Swipe instructions. Try that first.
If your problem is not resolved, come to the library for further troubleshooting.
Chromebook Clean Swipe:
Hold down Esc + Refresh + Power Button.
If your chromebook is able to be reset, a screen prompting you to "Insert Recovery USB Stick or SD Card" should pop up. Ignore this and press the power button.
Hit the power button again. Your chromebook should be reset and return to the login screen. If the issue persists, come to the library.
