I am having a weird issue with my [Laptop] when I plug it in to charge it, it cycles between:
“battery on” and “plugged in” every second
and the computer gets very very hot, and the battery doesn’t charge. If I shutdown the computer and plug it in, the laptop doesn’t get hot and fully charges, when I power it on while it is still plugged in it also is fine, but if I take out the charging wire and plug it back in to the laptop it stars the on/off cycle again.
I initially thought it was just a loose or bad female connector in the laptop, but it seems to be a software issue?
Any thoughts on what I should search on google to solve my issue? Ive already done quite a bit of searching and not coming up with anything.

But this does sound like it might be a bad battery controller, couldn’t say unless it’s tested. Easiest thing to do is to take a voltmeter and test the connections plus the traces on the battery controller.
Another test is to boot it up without the batteries installed but on ac power.
I would say it is probably a bad battery charge controller chip. One of the sense lines is not functioning. Often they will use a surface mount fuse or zero ohm resistor.
As many point out you need to confirm the battery is not suspect.
