iMac (kind of) dead
So the other day my iMac 5K 2015 died when I accidentally flipped a power switch on a power strip during an update from OS X 10.14.5 to 10.14.6.
Now all that happens when I turn it on is that the fan goes on (pretty lightly) and off with a 3 second interval. Nothing more. Black screen.
I’ve now turned it in to a repair guy but he hasn’t found the fault yet.
Things that have been tried:
- All types of resets (SMC, NVRAM) and short commands
- Leaving it off without the power cord plugged in for 24 hours
- Removing all RAM and starting (then it beeps and the fan goes on)
- Trying the RAMs separately one by one in the top slot
- Replacing the power supply
..and some more.
Does anyone know what the issue might be?
Esta é uma boa pergunta?
