Abruptly shutdown at login screen

[Tworks-WA]

Chromebook abrutly shuts off once it hits the login screen. I can almost get to desktop if I hit guest login immediately.  

Power status light on side looks good to about the time it gets to the login screen and than starts to continously blink.  This is the case only when the power cord is first plugged in.  After the first shutdown and plugged in it will continously blink.  The bootup process can be started again by the power button or opening lid with same results. 

We have tried a cold reset, new power brick, recovery, and even disconnected the battery to try without.  Battery indicator (when I can see it for the brief second) still says no charge even though it is plugged in. 

Issue occurs in developer mode also.  Seems to keep power for 6 to ten seconds and than thats it.  

Thoughts?

Hi! @Tworks-WA, Thanks for stopping by HP forums!

I understand the chromebook shuts down abruptly at the login screen.

Don't worry I'll try to help you out.

Did you make any software or hardware changes to your PC?

Have you tried charging your PC with a different adapter or wall outlet?

Try and check whether your fan is functioning because overheating makes a machine to shut down regularly.

Please try the steps recommended below.

It is not necessary to sign in to a Google Account before using Powerwash. Use the following steps to reset your Chromebook to its original factory state without signing in to an account:
   CAUTION:
All data saved on your Chromebook's hard drive (local storage) is deleted when you use Powerwash. Back up all important files, either on the Web or with an external storage device, before resetting the Chromebook.
On the sign-in screen, hold down the Ctrl + Alt + Shift + R keys.
In the Powerwash your Chrome device window, click Reset.

If the issue still persists, it is a hardware issue with your PC, please contact HP support for service options.
