A1226 won't boot : sleep light is on but no display
Hello ! I have a problem with my A1226 MacBook Pro : today, when I tried to wake it from sleep I heard the fan spining but no display, and the caps-lock key didn't work.
I shut it down by holding the power key, but when I tried to power it on again I had the same symptoms : fan spinning, the SuperDrive noise, but no display and the sleep light turned on. Caps-lock key didn't work either.
I tried resetting the PRAM and the SMC without any effect (in fact nothing happened when I pressed Command-Option-P-R right after power on). I tried connecting an external display but nothing.
I've read some things about faulty NVidia chips. Could this be one of them ? What can I do if it's the case (it's not on warranty anymore).
Otherwise, the fact that the sleep LED is on makes me think that maybe the sensor which detects when the lid is closed doesn't work, is it possible ?
Is this a good question?
