How to Fix M1 MacBook Air Won't Turn On

Показать описание

Today we will share how to fix an M1 MacBook Air that won’t turn on. Supplying power to the motherboard, we find that the voltage jumps back and forth between 0V and 5V. The measurement tells us that the working conditions of voltage boost from 5V to 20V are good. After rewriting the ROM data of CD3217 with U301, the MacBook now turns on normally.

How does the rom data get damaged? Per the name, it’s supposed to be read only…

Hi. Nice stuff. My question is; What caused the EEPROM to short circuit and lose it's power since it would have to be a UV exposure or a Flash. I'm perplexed.

So USB C Original Data files come with chip reader and software? If not where to get those files?

So basically all the voltages were good so the process of elimination lead to the rom data of the CD32** being scrambled so you need to rewrite it.
