Hi,
This board chime and I see the blinking folder.
Internal SSD is not detected, I tried 2 different, with Big Sur and Yosemite.
External SSD is not detected either, tried with 2 different
I am unable to do a PRAM reset, neither from internal keyboard or external keyboard, even with internal keyboard disconnected, then internal keyboard and trackpad disconnected. Unable also to use the Option key
When in insert a mouse in the USB connector, I have a stable red light
On J4813:
PP3V42_G3H =3.4V
PP3V3_S4 =3.4V
Any idea how to start the troubleshooting here?
