Hello Everybody
I m working on 2011 macbook air 11" , when plug power cable machine turn on 3 seconds later off and turn on again and 3 seconds later off again ...
Disconnected every thing and replaced known good I/O board same problem.
Checked PPBUS_G3H ,PP3V42_G3H ,PPVRTC_G3H and other S5 lines is stable S0 lines up 3 or 5 sec. then off. When connected mouse at usb port 2 second light is up then off then turn on again.
Also tried different bios, no sign of liquid damage. CPU is worming too much but then machine turn on in 3 second but PCH is cold.
