13" Mid 2013 MacBook Air wont turn on after update
A customer has given me a MacBook Air that will not turn on at all. I don’t mean it won’t boot, it wont power on. The only sign of life I can get is the fan. It turns on for a split second and turns off again. It will do this in an endless loop:
She claims that she was updating to macOS Mojave from MacOS Lion when it died. The charger she gave me is off brand and I have a feeling it may have fried it or something. I’m going straight to the assumption that I need to replace the logic board but I’m open to any of your ideas.
Here is what i’ve tried:
- Disconnecting the battery for 10 seconds
- Removing the SSD
- Booting off an external USB
- Holding down the power button for 10 seconds
- Resetting SMC and PRAM
- Charging the battery (with a 60w OEM Apple charger) for over an hour
Thanks in advance!
