Whether they offer you Depot or Apple is often a matter of discretion. Depot is a partner of Apple, and they are cheap, as you've noticed. As for the price difference, Apple has two means of repair - doing it themselves, or sending it to Depot. This is because the audio can be set to the lowest possible level (mute), but doing the resets restores it to a default that is audible. Sometimes machines will chime again if you reset the PMU/SMC and PRAM. While I overheated mine, I took out the battery and HDD. So in summary, the fix (at least for me) for the black screen, no chime, solid white light: is to overheat the laptop upside down under the bed covers and then let it set until it is cool. I am going to order a big cooling tray for it.Д«ut it seems it was overheating and affecting some connectors on the logic board.

I downloaded smcfancontrol and set the fan speed to max. While doing updates, the computer heats up. I thought there was a correlation with Lion, but I think it is just a heat issue. Once it was cool to the touch I powered it on and it worked. After about an hour give or take, I put it in the other room to let it cool. With it powered on, I covered it really good. So a day later I powered it on, but this time I put it upside down on the bed with the lid closed, so the batter was facing up. I set it up like a teepee again under the covers and overheat it. I did the update, restarted and the issue was back: solid white light, black screen, no chime. About a year+ worth since that's how long it was down. The next day it worked! I had the HDD out, so I powered it down and put it back in. After it got really hot to the touch, I set it in another room upside down overnight. I put lots of pillows around and covered it good. What I did was set the Macbook up like a teepee under the covers on the bed. I heard that this could be due to the Left Logic Board. I tired SMC resets, taking the RAM out, PRAM zap, etc. The Macbook must have overheated when I was doing the Lion update. I thought it was because of the Lion update. I had a disc in so I would hear it spinning.

After a Lion update I would push the power button and get a solid white light (from the sleep light), black screen and there would be no chime. If this clears up your issue, celebrate you have saved yourself a boat load of money. It will not hurt to still follow this procedure. Remember, this procedure is mainly for those who have gone inside of the machine to remove and reinstall the logic or I/O board for ANY reason. Then start the machine and repeat the idling process. If you have success, reinstall the 2 allen screws first then reinstall the back 4 screws only 2 at a time (the two closest ones on the same side). If it stay up without shutting down then you know it is something pressing against the logic board underneath causing an automatic shutdown issue.

If all is well shut it down and wait for 30 minutes then reboot it again, let it just idle without logging in. Then start the machine and if it boots normally then just let it set idle for at least an hour. If you did then try these steps: remove only the two 'allen type screws' completely (located behind the memory cover plate) also remove the four (4) screws located at the rear bottom side. While there are a lot of things that could cause this problem I take it that you have not opened up the top cover case. Now, I have theДЄ1151 model (first generation of Macbook Pro) which does not have the NIVIDA video chip.
