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.īut 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. iMac You'll find the 'Power' button behind the lower-left side of the iMac's screen.

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.
#Turn off macbook power chime 2017 update
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!Īlso, my lid light is on solid white, but it's dim.
#Turn off macbook power chime 2017 mac osx
My Macbook Pro is a 15 inch, early-2008 one, running Mac OSX Lion.Īlso, 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.
