Not booting after replacing upper case
I had my 12" fully operational, with the upper case unattached, screws out, and no battery installed. installed Tiger, put in an empty battery, powered down, and charged overnight.
Just put the upper case back together with all screws, tried to boot up, and I get the fan, but not boot, no screen, no chime, nothing. I'm completely baffled, because the only change between yesterday and today is that I reattached the upper case. Removed the screws and battery, and still nothing.
