Hi All

I have a Macbook Air which will draw approx 3amps when connected to battery and plugged in. Then will hover around 2.1amps after about 20 seconds.

Fan spin up to 100%
No video output / screen
No Bong

Not sure where to start with this one!

Check for USB activity on bothe ports.

Do you get all voltages, including VCORE?
PLT_RESET_L goes high?
Any history fault available?

"USB SSD connected to both USB ports lights up."
Do you note flashing Link LED???

You cannot have any activity on the board, if PLT_RESET_L stays low.
Post U1950 voltages.
