hi guys I have the above MacBook Air
ive got the schematic for it and the boardview file.
but I can't for the life of me figure out what's going on.
its as if its dead the MagSafe light turns on when connected and goes to green to say the battery is charged.
but there is no signs of life other than the fact that if I press the power button when I have a usb dongle connected it will spring to the life (the usb stick I mean)
but nothing else no fan spin no backlight no chime
nothing.
ive tried an SMC reset which seems to work.
but still no power on.
ive removed the bottom cover and can see no sign of water damage or anything.
it just was on then shut down and never came back after.
ive tried a new battery with the same results.
as I have the board files ive checked the board for shorts and find loads around the circled area.
but if I check for voltages im getting 8.5v on all the caps marked NEHAV7
thanks for any help.
