Steps to reproduce the problem:
1. Battery drained from watching Youtube
2. Upon plugging in and immediately turning back on a message says "Critical OS Update DO NOT TURN OFF"
3. Chromebook turns itself off
4. Chromebook only displays Chrome logo and eventually a blank screen with a moveable mouse cursor

What is the expected behavior?
To not bork itself

What went wrong?
My computer shut itself off after the battery had drained and when I plugged it back in it tried installing a critical update. Even though the power cable was securely plugged in, apparently the program expected me to charge the battery up for a few minutes before turning it on again. But that was not the case, and the Chromebook shut itself off during the critical update installation. Now my computer will not boot or do anything but load the Chromebook logo and eventually after being on for a while it will display a black screen with a cursor that I can move with my mouse. 

Did this work before? Yes I have no idea since I cannot use my Chromebook. But it was the latest Developer Mode version

Chrome version:   Channel: stable
OS Version: Latest
Flash Version: 

Is there a way to recover the hard drive? I do not want to do attempt powerwash because I have a small bitcoin stash (well, it was a small when I loaded it a year or two ago) stored on it.
