Re: MacBook Pro 15" 2017 A1707 Touchbar No power




Hi everybody, I have a A1707 MacBook 2016 that turns on then powers off after few minutes. It cannot turn on when I use the PSU only with the type-c charger or battery. Now there's no os on it. SSD does not show when booting from drive on startup however it does show in disk utility. It powers off after about 1-2 minutes into installing OS from storage drive.

PPBUS 13V...
