first of all, big apple-enlightened of forum have helped myself , others expertise.
said, reason made account because have appears unique problem, haven't been able find searching forum's older posts, nor elsewhere.
short version: macbook pro 2 dented charging pins has ~50% chance of shutting down when unplugged, not when connected charger unplugged wall or unpaired power brick. others have had similar problems, sounds more of battery issue i'm guessing in case charging port issue. help?
long version: topic title sums problem, more specifically, mbp shuts down when charger unplugged way. then, seems random. when charger jerked out (which rare, accidents happen) there seems 50/50 chance of laptop shutting down immediately. in, black screen, fans shut off, etc. instant it's unplugged. dead laptop.
happens when unplugging laptop itself, never when disconnecting charger brick or unplugging wall. when happen, can laptop turn on charger plugged in.
i've been able avoid , pulling charger upwards (kind of pivoting on top edge) when need unplug. have older, boxy charger, not new cylindrical one, if makes difference. should charger light , battery lights behave normally.
i'm guessing has little battery since unlike others' similar battery-related problems, don't have x on icon , behavior seems random, regardless of charge level. battery beyond needing replacement, though (959 cycles , 63% design charge capacity), blame.
it's worth mentioning mature , responsible friends involved in incident involved mbp falling couple of feet , receiving 2 bent pins inside charging port…thing. it's not severe, it's leading culprit far can tell far. i'll post pics if needed.
covers everything. if specs necessary, i'm happy oblige. so, have ideas real problem might be, or ideas how start diagnosing?
try resetting smc , calibrating battery. see link on troubleshooting magsafe adapters in charging section of following link.
