A1260 fan starts + latch LED lights, doesn't boot, no sounds
My trusty A1260 / EMC 2198 with last 3 serial YJZ is misbehaving.
After leaving it alone, lid closed, nothing plugged in except power, for a couple of days, I came back and found the front latch LED glowing a steady white, could hear the fans running and it was quite warm to touch (though no more than usual when its running - it was in a well ventilated spot).
I opened it and the screen was black and the keyboard lights / volume buttons had no response. I held down the power key and after ~5s everything turned off. This happened once a couple of days ago, but it powered up as usual without problem. But not this time.
I tried to boot as usual, and the following happens when I press the power key:
- fan starts
- CD drive makes a noise (I think, possibly HD?)
- front latch LED goes white (at half brightness)
The screen does not light up, and nothing else happens after this point. I can power if off again by holding down the power button for 5s.
Things I've tried:
- reseating the RAM cards
- booting with/without the power attached
- removed battery, held down power button (SMC reset?)
- booting with no RAM -- exactly the same as above
Any suggestions on next steps / tips are much appreciated!
Edit: I just noticed that if its in the zombie state, when I close the lid the latch LED goes from subdued white to bright white (steady in both cases, not flashing). If I re-open the lid, it goes back to dim. Not sure if that's a clue? I've also hooked up an external display - nothing shows there.
Это хороший вопрос?

Dang, Apple called me back within 3 hours of dropping it off -- all fixed with a new logic board and no charge under the nVidia recall! I'm a v happy camper! (Plus they obviously cleaned it too and its running *much* cooler).
Now for the SSD upgrade...
