MacBook turns off/sometimes bootloops when charger is removed
I have a 2.2Ghz variant of this laptop which is exhibit a weird issue. It seems to work fine when on the charger but as soon as the charger is removed it will either freeze and shutoff or shutoff immediately. The battery is detected and is in supposedly good condition. It then proceeds to either bootloop or get stuck with the display off, trackpad and keyboard dead but with the keyboard backlight on.
The only way to get to bootup again is to plug in the charger, then clear SMC and then press the power button. Have tried the on device diagnostics but it didn’t pick up any issues. Anyone have any ideas?
I also checked the Apple Service Program for Mid 2015 and it seems that mine would be eligible. Could it possibly be a bad battery and would they replace it, because they would need to use a charger to run the diagnostics.
Thanks for the response. Added the coconutbattery snapshot in the original post. That and the diagnostics were the first things I did.
As for which service program. I was referring to the following: https://support.apple.com/en-au/15-inch-...
I am more than happy to to repair it myself. Long time tinkerer and basic electronics repairer, so I am not afraid to get my hands dirty but if board repair was required, it would be slightly above my current capabilities.
Edit: Should say, this isn't my laptop. Bought it for a stupid cheap price and I mean stupid cheap. Opened it up and it was truely disgusting and chock full of dust. No signs of water damage though except for a little bit of greenish residue on the magsafe daughter board which I cleaned up with some iso.
