MacBook Pro Not Powering On; SIL Blinks w/ Power Button

[SRASC]

Have a 2011 MacBook Pro, which currently has some battery issues where the battery wasn’t charging and eventually went to 0%. Though I was able to power it on off of AC power until recently.

Now when I try to do that it the SIL (white light on the front) blinks (not beeps) 3x or so and powers off. Then repeats & it never powers on.

Any suggestions as to a cause? About to order a new battery to replace the existing one.

(Thought I should mention that in all these issues, my MagSafe adapter always indicates green when it is plugged in)

Well you can pretty much say the battery is now an anchor.

Open her up, remove the battery and see if the same issue exists.

If not, then it's the battery.

If so, the logic board or RAM maybe the culprit.

I got it to turn on, but the battery doesn’t seem to be charging. The MagSafe is green but the battery is at 29% currently.

I have the same issue on my MacBook 2011. Were you able to resolve yours ?

Um, sort of yes and no?

I left it unplugged for weeks, plugged it back in one random afternoon for the hell of it and it started charging to my surprise. Took a couple of hours but once it turned green I powered it up and it ran as normal at 100%. Though the issue isn’t actually resolved. The battery still loses charge, slowly, like 1% a week, but once it reaches below 95% that accelerated to 1% every 5 mins. Though the last couple of days it dropped below 95% and the drop rate seems to remain the same, 1% a week.

If/when it does drop faster I tend to shut it off completely, unplug it and leave it so for a couple of days. Then plug it back in and hope it starts to charge, let it charge to 100% and get about a month with it.
