Then at the menu hold Command + D until it begins to boot (or reboot) to the Apple Diagnostics (no idea why it cannot have its own menu option or why they have to stray from the Intel keys). What do you think?Īlso, you must boot the M1 Mac by holding the power button down until you get the menu. The screen works, the speakers work, the fan works, the power supply works, the hard drive works (at least I think), CD Drive ejects, screen works (but doesn’t turn on really, only shows a single color at a time, usually nothing, but can be white or grey). Currently speaking, Num Lock and Caps Lock don’t work. Resetting PRAM rarely gets any reaction, and the caps lock key worked only once (when apple was helping me). Any suggestions? Resetting the System Managenent only gives me a high pitch beep, but it does only sometimes. I just realized that if I let it be for a few minutes (like 10 maybe) the fan will shut off. I can get it to bong only if I remove the ram and put it into a different slot and pretty much just mess with it a bunch. If I removed 1 ram stick (there are 2 sticks, 512 mb each) then I could get it to bong, but then it was back to square 1 after a day. I also realized that the ram had some kind of white stains on it near the slots it plugs into. I don’t have the battery connected to it right now l. Sometimes it will do the startup sound, and the grey screen will last as long as the sound is playing, but then disappears. After resetting NVRAM and other stuff, it changed from a grey screen to a white screen. At one time I was able to get it stuck on a grey screen, but haven’t been able to since. ![]() ![]() ![]() I contacted apple, they did everything they could (and it kinda did something different). I took it apart to see what was going on in there, cleaned it, but it still did the same thing as before. You see, at first, all it did was when you plugged it in, after a few seconds, the screen would flash grey for half a second, and at the same time the fan would go full blast. MacBook flashes grey and then doesn’t turn on! Fan is at full blast’ I received an old MacBook from a neighbor that was about to throw it out because it didn’t work.
