Title:

MacBook had power adapter disconnected for 3-4 months, now won’t boot

Text:

Hi everyone,
 
so I got a MacBook Pro a year and a bit ago and it was working beautifully. I’d disabled the Radeon card as I’ve heard the horror stories and had no issues doing the basics. [br]
 
 
the last few months have been crazy and I haven’t touched it, at some point the MagSafe connector got bumped off. I came to it today, saw that and reconnected it. The light went from orange to green pretty quickly and I tried booting it, no luck. [br]
 
 
I pressed the battery indicator hoping to get a status and it blinked 5 times, which with no knowledge of anything struck me as a bad sign. [br]
 
 
I tried a batch of troubleshooting tricks. Reset SMC - no go. Leave it to charge for a couple hours, also no dice. The closest I’ve come to figuring stuff out was a trick I found that had me holding the power button down and while doing so plugging the MagSafe back. I got the boot up screen and sound, fans were going 100% and the progress bar on the boot screen started to move. This was disappointing as it got to 50% and the system shut down and went into a perpetual boot loop. [br]
 
 
I know from the previous owner that he had to get repairs done for the Radeon issue and I’ve made sure to run the integrated video card ever since I got it and keep it as cool as possible. He also identified that the battery even with relatively few charging cycles didn’t keep the system running for long which I didn’t care about as I exclusively use it plugged in. [br]
 
 
but alas here I am now. Because of its age I don’t really want to sink a fortune into it. I’d be okay doing a battery swap but even $120 (Canadian) is a hard pill to swallow for a device that I don’t use with any real frequency. [br]
 
 
that said I really don’t want it just to go to recycling, I would love to have it as a secondary machine - thanks in advance for any help or advice.

Okay first I want to thank everyone for their replies. [br]
 
 
I’ve tried a trick to see if I can get the Mac to boot assuming the issue was with the battery. [br]
 
 
I’ve disconnected the battery and did the same trick as I had before, hold the power button for 10 seconds, plug in the MagSafe connector, release the power button and it started to boot like it did before I removed the battery. [br]
 
 
the system goes into a boot loop like before. The progress bar gets halfway and then the system does a full restart, repeat ad nauseum
