Re: MacBook Air 820-00165-A PPBUS-G3H <1V

check voltages without anything else attached - only dc-in board. Measure resistance on ppbus_g3h.

Re: CH341A problem reading bios chip

Did you insert the test clip correctly into the programmer (see pic)?

Do you get a red light when you plug it in?

Can you detect the chip in the software?
