Macbook Air M2 is not charging
My Macbook Air M2 is not charging (I've had it for 10 months). The battery is 1% the whole day. I was trying to reset PRAM following these steps:
- Shut down your computer and disconnect all USB devices (except wired keyboards).
- Press the power button to turn on your Mac.
- Immediately press and hold the Option, Command, P, and R keys on your keyboard. You need to press this key combination before the gray screen appears or it won’t work.
- Hold down these keys for 20 seconds, during which time your Mac will appear to restart.
- On older Macs that chime upon startup, hold down the keys until you hear a second chime.
- For Macs with the Apple T2 Security Chip, hold the keys until the Apple logo appears and disappears a second time. Here’s a list of Mac models with the T2 chip.
Release the keys and let your Mac finish rebooting.
However, when I shut down PC, it turns on automatically. I press the mentioned keys before the apple logo appears on the screen and hold until it's done restarting, but it doesn't work. I also used the terminal to reset PRAM, but it gives me these errors:
nvram: Error clearing firmware variable fmm-mobileme-token-FMM: (iokit/common) not permitted
nvram: Error clearing firmware variable fmm-mobileme-token-FMM-BridgeHasAccount: (iokit/common) not permitted
nvram: Error clearing firmware variable fmm-computer-name: (iokit/common) not permitted
Is there anything else I can try?
