R5 571 "Dead" & Power supply input "flakey"

jerswing

1) 2nd time in ~2 months, R5 571 appears totally "dead" Will have to pull power, unscrew & remove bottom cover (ARGGGGH!!) to remove battery, followed by Power button & reversing all prior steps
2) ?Anyone know (A) What causes this nonsense? - and - (B) How to avoid it recurring?
3) Also barrel connector/jack for power input is now flakey: have to insert, carefully rotate & stop on one of perhaps 3 "sweet spots" where it actually charges laptop
4) ?Anyone have direct, relevant & helpful experience in resolving this??  (BTW - it's an after-market power supply, which worked just fine for ~9+ months)

Does the same problem occur when resetting the battery?

What is the version of the bios? Does your model have a button like this somewhere on the motherboard?
