13" Mid 2013 MacBook Air wont turn on after update

テキスト:

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:

[video|2350]

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!
