Chromebook Does Not Start (Chrome OS)

This document applies to HP Chromebook computers with Chrome OS.
This document provides possible solutions to HP Chromebook startup issues, including the Chrome OS is missing or damaged error condition. Follow the steps in this document to help isolate the startup problem and find a solution.
Step 1: Remove external devices
If your Chromebook does not start, remove any and all USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices (external hard drives and similar).
After you have removed all external devices, turn on the Chromebook. What happens?
  • If the Chromebook starts, reconnect devices one at a time while restarting the computer to figure out which device is causing the problem. You are done.
  • If the Chromebook still does not start or exhibits the same problem, do not reconnect anything, and continue troubleshooting.
Step 2: Find a fix that matches your Chromebook's symptom
If your Chromebook does not start, read from the following list of symptoms. If you find a symptom that matches your computer's condition, follow those instructions. You might be directed to another support document containing detailed troubleshooting procedures. If you cannot find a symptom that matches your computer's condition, proceed to Step 3: Perform a hard reboot.
Step 3: Perform a hard reboot
A hard reboot can resolve many Chromebook startup issues. Follow these steps to perform a hard reboot:
  1. Turn off the computer.
  2. Disconnect all peripheral devices and remove all USB devices and media cards.
  3. Disconnect the AC power adapter. If the Chromebook features a removable battery, remove the battery.
  4. Press and hold the power button for at least 7 seconds.
  5. Reconnect the AC power adapter.
    If you removed the battery, do not reconnect it at this time.
  6. Turn on the computer.
    If the computer starts, you are done.
    If the computer does not start, continue to the next step.
Step 4: Perform a system recovery
If the steps in this document have not resolved the startup problem with your Chromebook, perform a system recovery to reset the computer to its original factory-shipped state. For more information about Chrome OS system recovery, see Performing a System Recovery on Your HP Chromebook.
