My MacBook Air won’t turn on
I’ve tried undoing so accessories and holding the power button for 10 seconds and nothing happens.
MacBook Air 13″, macOS 12.7
You can try clean PRAM Battery, instructions are available on iFixit.
If this doesn't work try cleaning your MagSafe port and charging it for at least 24 hours.
Try changing your SSD (if you have an older model). If those don't work you may try to go to an Apple store or Apple authorised store to see it. Tell them to try and use a charger of theirs. If it doesn't work, lend the MacBook to them to see it and they will update you in 1-2 business days.
