My chromebook is acting really weird

Hi guys usually my chromebook is acting really weird (It’s a BLUEBIRD)
To not charging and sometimes not even turning on
and when it decides to work the battery indicator reports that there is no battery installed even tho there is one, disconnecting the charger doesn’t change anything since it continues to report that there is no battery installed
I even tried to reflash/update the firmware and it seems that nothing was solved
and while on windows sometimes it is just going to randomly start to shut down not a instant shutdown it is like if i had pressed the power button or as if the battery was low. My only guess is that the issue is a bad battery
So should i buy a new battery or should i just remove this possibly bad one. If i should buy one where can i buy one
Apreciate any help :slight_smile:
