Strange magsafe behaviour after battery failure
Hope somebody can help with this as I've been researching for about a week now...
Macbook pro 15" early 2011 i7 2.0ghz
The issue: magsafe only works intermittently after battery expanded and failed. Its a bit random if I unplug it a few times and jiggle it about it may come on and work as it should..once it's on it stays on....
If it's working and I quickly unplug and replug 95% it will come straight back on.. Its not a short or cable issue in the magsafe..as I've tried 2 new ones so far.. There was no damage liquid or otherwise apart from the expanded battery issue... when theres no magsafe light the mac is running as if on battery,.
Steps taken:
Smc/pram reset
Brand new magsafe (original)
Swapped out dc in board
Brand new battery
Different plug sockets
Different power cable
After trying another magsafe the issue remains.. The best it's been was at my work where it always came on but took between 5-15 seconds. At home I'm trying it and it's just hit and miss. Just hope it isn't logic board smc damage due to the previous battery failure. But then why would it work normally when it does? Could it be the dc in connection on logic board?. In istat the dc in is showing 1.8a and the charger behaves normally when it works..
as i type this its working and the mac is fully charged,... if i unplug the L plug and replug it comes back on but if i turn off the plug socket switch or unplug from the wall it does not work when plugged back in,. so i wait 3 minutes then unplug and replug the magsafe into the mac and it comes on??
Any help would be great
