Mother Board : S.O.S.
I tried an impossible repair for a customer
MacBook Pro Mid 2009
After updating interrupted, does not start. The motherboard is SOS: 3 long beeps, 3 short and 3 long
I tried everything I believe:
Reinstalling Firmware 1.7 for this model, the CD is rejected (I burned CD 3: the same)
Replacing RAM: Nothing
Replaced the battery, disconnected the battery ...
Unable to start external hard disk or DVD with install., The keyboard is not functional.
If someone in another track, I'm interested, but obviously replace the motherboard!
Firmware Pb, pb Burning CDs or DVDs
Big thank you in advance
Is this a good question?
