Mac wont start up, both fans spin for 2 secs, Sleep LED blinks once
last 4 of serial # DV7L
When trying to power up with power button :
- Mac starts
- Both fans spin for 2 sec
- Sleep LED blinks once
- all shuts off, cycle repeats without pushing power button on
Battery indicator full. When I unplug battery with adapter attached, Mac wont react at all.
Tried different RAMs, HDDs, SSDs. Reseting SMC, NVRAM, 20sec battery unplug - no luck.
Any of you guys had smth similar with POST ?
Ist dies eine gute Frage?
