Won’t charge or turn on unless plugged in
MacBook Pro 2014 15’ won’t charge, turns off immediately after disconnecting charger, MagSafe cord is always orange unless I do smc reset in which it turn green until it turn back on then goes back the orange. Pressing show battery status in system preferences immediately un-checks itself.
It’s running Catalina, i did smc reset, pram reset, nvram, I sat on the power brick, I shook the MacBook, I left it charging all night, and nothing, still won’t charge, like I said it does turn on plugged in.
Also some apps feel slow, (maybe that’s just my problem)
The Mac has 16 gb ram and 500 ssd

For some background I got it at a thrift store, so I don’t know what previous owner might have done, but it turns on and works while connected to charger
