Starting a few days ago, my Chromebook's boot-up process has gotten messed up. Instead of getting the dark background and my avatar with a password entry box underneath, I get a white background and my avatar with my Google username displayed underneath -- no login box. In order to login, I have to double-touch my mouse-pad, which brings up the login box.
When awaking from sleep, I also get the white-background screen, although the password box is displayed.
This started after I ran out of battery while using it. When I plugged in the power supply and re-booted, the behavior first appeared.
Anyone else have this issue, and any tips on how to fix it, save reinstalling the operating system?
