Chromebook 4 - When I put the charger in it blinks red to green to blue.

[user0KKUvbPWse]

I now have two of the same device doing this which worries me.  I have over 150 of these in use at a school.  When  you plug in the Chromebook 4 it just cycles the light on the side from red, to green, to blue.  When it gets to blue the screen lights up for a second then it goes black and the light on the side starts the cycle again.   I disconnected and reconnected the battery and I did the esc refresh thing.  Has anyone seen this issue and know what is going on?

Thanks

Hey, does the device still power on when this occurs?

For a quick second it powers on when the light is blue.   Then the cycle starts again with the red and green lights on the side.

Just want to confirm have you tried the troubleshooting steps in the link below?

Ours will power on if you disconnect and reconnect the charger. Power wash does not fix it.

We are having this issue. About 15 out of 700 or so.. It will power up if you unplug the charger and then plug it back in. It does not recognize the battery at all. If I put in a battery from a working one it works just fine. It seems hard to believe that we have 15 dead batteries already in less than two years.

I an also having this issue, it blinks between the colours at random and wont boot.

If the troubleshooting article did not help I recommend letting a service technician have a look. As we would like to gather additional information and look at this from a case by case basis please provide the full model code and the serial number of the device as well as your best contact phone number, name, and email.
