Clarky, I'm pretty sure that now your just attempting to break your PC. I mean this is like the second time now? LOL Maybe you just don't want to be here anymore, looks like we need to demote you.
In all seriousness I hope that you fix your PC soon!
it could really look like a problem with the battery or possibly the cable (i have no idea how to work with computers) but you should try with another cable for the battery of the pc and see if that solves it
UPDATE: I've tried repairing it myself but still no use so it's been sent to a repairment shop so they can try check out the issue. It may take a few days due to business hours.
