Disabling Write Protect via Battery


This method requires opening your device. Be sure to use the correct tools to prevent hardware damage.

Step 1: Open the device and disconnect the battery

  1. Power down your device. Close the lid and flip it over.
  2. Take out all of the screws.


Screws may be underneath "feet", or the material that keeps the Chromebook from sliding.

  1. Gently pry the back off the Chromebook. If you do not have the proper tools a dull knife would be helpful.
    • On some Chromebooks, the keyboard needs to be removed instead of the back. Be careful as there's a ribbon wire underneath that needs disconnecting first.
  2. Unplug the battery connector. You do not need to take the entire battery out of the Chromebook.

Step 2: Boot using AC power, and flash.

  1. Plug the Chromebook into a power adapter.


There is a 15V USB-C PD requirement for booting without the battery.

  1. Boot the chromebook up
    • If you removed the keyboard, make sure to reattach it for this step.
  2. Contmnue to Flashing Firmware
