MacBook had power adapter disconnected for 3-4 months, now won’t boot
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.
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.
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.
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.
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.
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.
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.
Update (09/05/2019)
Okay first I want to thank everyone for their replies.
I’ve tried a trick to see if I can get the Mac to boot assuming the issue was with the battery.
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.
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

How did you disable the graphics chip?

I used Steve chow’s fork of gfxstatus
It still will ping the discrete chip during some system events and on boot, but the chip mostly works for the time being so I’m not too stressed
Also installed a different fan management program (Macs fan control) to keep the temps as low as possivle
