Wait a few minutes, then restart normally. Then do a normal shut down, allowing it to spin and write itвЂ™s exit code. The fans will be on high, but let it boot all the way through to the home screen, if it makes it. It should start up after you push the power button after letting go. Hold down the power button for about 30 seconds, the apply power by the power supply while holding down, Continue to hold down for another 30 seconds.

You can buy that software on his site, but without the physical bypass, it's only a temporary fix, until you clear the PRAM or NVRAM.ДЄs far as the top question, IвЂ™ve had luck with turning off the unit, taking the battery out. So, if I do get one in, I let him do it for me for a modest price. I stay clear of that year, but MadMod is only 30 minutes away from me.

It was an Apple recall to replace the Radeon gpu, but even after replacing it, they still eventually failed.

Either way, you're faced with making the system believe that there is no other graphics processor but the onboard intel gpu. Or, software and a jumper cable to bypass and keep the sleep function working.

I've done several and both involve, either soldering wires to pads to jtag code onto the logic board. Or, you could bypass it using RealMacMod's method. The only 'permanent' fix is to jtag the unit using dosdude1's method. You can even have the GPU reballed and it will work for a while, but overheat again and return. Some software fixes work for a while, but it always comes back.

Then download smcfancontrol.You'll need a hardware bypass on the grey screen to permanently disable the GPU. 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. This never happened before!ДЄlso, my lid light is on solid white, but it's dim.

#MACBOOK PRO A1278 2011 VIDEO DISTORTED OR BLACK SCREEN MAC OSX#

My Macbook Pro is a 15 inch, early-2008 one, running Mac OSX Lion.ДЄlso, my Macbook won't start with only the battery. Nothing works! The screen stays in darkness and no chime can be heard!

I also tried to leave it alone for a couple of hours, unplugged and without the battery. I have tried unplugging it, removing the battery while it's unplugged, resetting SMC and PRAM, have tried booting from the Mac OSX disk. I'm pretty sure I had the volume up high before I closed the lid, as I was watching a video on YouTube when I closed the lid. After that, I got a phone call, closed the lid again, came back after ~5 mins, and the screen was also black! Except that this time it would stay black and won't turn-on properly! The next day, I woke up, took the Macbook out, opened the lid, but the screen stayed black! Not thinking about it, I pressed the power button until the Mac turned off completely, then turned it on again, and it worked! Then I suddenly woke up at like 4 a.m., I closed the Macbook's lid, put it in its bag (that wasn't a smart idea!), and went to bed. So last night I was surfing the internet, and I fell asleep.
