Any application or software I have open stays fine. Something to keep in mind is that only the background goes black. When it goes black, the dock at the bottom slides out and then slides back up when the screen goes to the regular background.

Removing ram and changing the ram amount or configuration will force it to re-examine the parameters of the board and environment. My MacBook pro background keeps going black every 4-7 seconds. I’ve also used the system boot USB drive, to boot from and run diagnostics on the board. It’s a trial and error thing, but that has worked for me in the past. Getting it to boot all the way through is paramount in rewriting the exit code properly. It’s really a bad instruction set at boot that needs to be re-written (kext) from my experience. You can also start up in safe mode by holding the shift key down all the way through the boot procedure. The fans should spin up, but then return to the normal state. Wait a few minutes, then restart normally. Then do a normal shut down, allowing it to spin and write it’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.Īs far as the top question, I’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. If you’ve correctly configured the sleep settings but still the monitor goes black randomly, it’s probably because the screen saver is set to Blank. 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. You'll need a hardware bypass on the grey screen to permanently disable the GPU.
