My MacBook Pro screen randomly goes black, yet the laptop still has power. I usually have to reboot in order to get back into the computer.. as moving the track pad doesn't bring the screen up.

My MacBook Pro 2010 15 inch screen shuts off randomly. The whole laptop doesn't shut off just the screen. It calls it a panic but I have to hold down the power button to shut it off when this happens or it will stay on the black screen.

I have my macbook pro with 2.66GHZ, 320GB, 4GB RAM..It runs properly however it shuts down randomly. Sometimes after one hour other times after just a few minutes. Am wondering what the problem could be. I have done all teh PRAM resets. Thought it was the fan but the fan runs normally.

For the past few days, my mid 2012 15" rMBP has been powering down or sleeping while in the middle of performing tasks, and more importantly when it's ABOVE 15% charge. Just today however, I now have a red battery indication at 52% and holding.
At the time, I had an external monitor plugged into the thunderbolt port closest to the ac adaptor port. I was running Adobe Lightroom and Photoshop, but nothing else, and was not connected to the internet. I had turned wifi off. My problems continued until I plugged in. Once on a full charge, I unplugged and the same thing happened all over. Numerous times. So, I disconnected the external monitor, and thought that solved my problem. The next time I used the computer, I put the external monitor into the other TB port and did not have any issues, however I wasn't using the rMBP as extensively.
Today, again while performing tasks such as importing/exporting images with LR & PS, my laptop shut itself down. It runs warm, and fans are purring like crazy, but that's normal for the work I'm doing. Prior to the shut down, the battery read ~24%. I plugged in and woke it up. No external monitor is attached today. I am not running any other programs besides Chrome at the moment. I noticed a red battery light at 52% and it has not changed. Option clicking the indicator shows a "normal" condition.

I have a 13-inch Macbook, Late 2008 model, using iOS Mavericks. While on battery power, the laptop will randomly just turn completely off, despite still having plenty of battery power left. I know it's not a calibration issue where the battery is dead but appears to have charge left, since I'm able to turn the computer back on again and continue using it.

I have a mid 2010 MacBook Pro that has been shutting down randomly for quite a while now. It seems to happen most when I have more than one application running but sometimes happens with nothing running at all. It seems that the screen goes off and the sound skips but the keyboard light is still on. I thought it was because I had a bad hard drive but I replaced it and it still randomly shuts down. I ran smart utility and it all passed. I just don't understand what can be causing this? I take this computer to school all the time and it's kind of embarrassing having this shut down on me mid-presentation.

I dropped my MacBook by accident earlier today and circa three hours later I am experiencing problems I have never encountered before. Now, my MacBook shuts off every 15 minutes or so and the last time it shut off, the screen went completely dark and the computer began making a regular beeping noise, and it smelt like something was being burnt... Lately I have also been noticing that when charging the charger tends to get heated up easier than before, and to higher temperatures as well.

My new Alu iMac just randomly shuts off. It's happened like 5 times (once while I was typing a paper). I have updated to 10.5, and it has happened twice since the install.
View 16 Replies View RelatedI have an old iMac G3 (400mhz slot loading) that I got second hand for free. When I first got it, it seemed to work perfectly in every way, but the hard disk wasn't very big so I tried to install a new (larger) one. Everything seemed to go fine, but after the upgrade, the computer would only stay powered on for about 10 minutes before shutting itself off. I assumed that it was a problem with the hard disk, so I put the old one back, but the problem persisted. It will only stay powered on for a maximum of about 20 minutes before blinking off and then it has to sit for a while before I can get another 20 miutes out of it

Safari randomly shuts down while in the middle of browsing. The rainbow loading icon will appear and then all windows and tabs will close. Then it gives me the option to report or ignore the problem. This happens at least once every day. Also, Software Update does not load. It just says "The Software Update Server (appleupdate.iu.edu) is not responding."

I do not have AppleCare on this machine. I've got a 27" iMac that will randomly shut down, be it in the middle of playing music on iTunes, while I'm typing a document or while the machine is simply in screensaver mode doing nothing. Usually the machine tries to instantly reboot itself. All too often, it cannot be rebooted and I have to let sit for quite sometime before it will even power back on. Lately the problem has gotten worse, almost never reboots by itself.
Finally, in the last few days, it just won't turn back on. Nothing. My biggest concern is that I have an unreleased music album from an instantly recognizable major client on the iMac's hard drive, not due out for many more months and still unannounced. I can't simply take the computer into an Apple store for troubleshooting as those files are worth and could cost me exponentially more than even a new iMac outright ever would.
lately, my mba has been behaving a little weirdly. its screen would suddenly become a little dimmer when the brightness in the room has not changed a bit. after a long while(15 min?), it'll turn brighter again by itself, and again without any change in the lighting of the room. the change is not big but obviously. any idea? can it be some software? or setting? or a defective light sensor?
View 2 Replies View RelatedSo my computer froze while I was waking it up from it's nap, so I restarted it by holding down the power button. It now shows me the gray screen, apple sign and spinning circle for about a minute before it's decided it's done and would like to turn itself off. I have tried resetting the PRAM and the SMC. I have tried restarting in safe mode. I tried to restart it off the AC adapter without the battery. I hear the chime, I see the apple, and the status circle, and then nothing!
View 4 Replies View RelatedI have just replaced the display panel in my MacBook Pro (A1260) and now it is behaving oddly at startup. The backlight lights up normally until the boot process gets to the Login screen, at that point the LEDs shut off. I can see the images on the display, (the LCD seems OK,) the only issue is that the LEDs are turning off.
Here's what I've tried:
1) If I boot in Target mode, the screen stays lit. (As expected.)
2) If I reset PRAM, the lamp behaves normally, staying on through that session. If I restart, the lamp-off- condition returns.
3) I have reset the SMC per instructions here, [URL]. No change, LEDs shut off.

I came home to discover my power cord had died and my laptop turned off due to no power. I used a friend's power cord to turn it on later that night and send some emails. I bought a new power cord the next day, plugged in, and turned the laptop on. It stayed on the gray screen with a spinning wheel beneath the apple logo for a while. I restarted it and it turned off after a few seconds of the gray screen. An empty bar flashes twice horizontally at the bottom before the spinning bar begins.I tried booting in safe mode, but it would just stay on the gray screen. I tried doing shift+command+v and received a message about keys out of order and disk error full, can't repair. I was able to boot from the install disc, and when I click "Repair Disc" I get the same erros. Not sure what to do now?

Ever since I sold it here on MR and got it back, there has been a problem with my 12" Dual USB iBook G3 500MHz's screen (lord, that's a long name). Whenever the screen is tilted back farther than 45 degrees or so, the backlight shuts off. I can open the casing and fix it if it's possible. Does anyone know what the problem with it is? I'm trying to get it fixed up and ready to sell back to my friend as his first Mac, and I'm trying to get every problem resolved

Grey screen with apple and spinning progress then shuts off
View 1 Replies View RelatedAt least, it seemingly randomly turns off. I can be surfing the web or whatever like normal, but then after a period of time the monitor goes black. I can see that the computer hasn't shut off, but it's as though the computer is on its lowest brightness setting. It can be temporarily fixed some times if I lower the brightness all the way via F1, then put it back up, but if it goes up more than 3 or 4 boxes it goes black again.
It also goes black if I were to move the monitor any time during this whole thing. I've heard things like an inverter cable and board, but I have no idea what's going to fix this. This is my only computer, I use it for all my school work, if it breaks permanently I'm screwed.
My MBP has all the sudden started to throw a black screen at me. i have to restart my MBP every time this happens. I have tried doing a fresh install and starting fresh and this doesn't help, I've even installed every app one at a time and tried to figure it out.

My MacBook is from 2007, so it is old and has its problems.When I turned it on one day, it was all normal, and randomly the screen got so dark, it looked like the computer had shut down on me. I knew it was still turned on though because the little light was indicating that it was on and it was still making the cd drive/booting up sounds.
After a while, I noticed that the screen just went very very dim, because I could still slightly see the webpage I was on. Turning up the brightness of the screen did nothing, same with restarting the computer.
Sometimes the screen would come back to the normal brightness, until I would go to do something on the internet and it would go very dark again. It's so unpredictable, I don't even want to deal with it anymore.
Fairly new MacBook Pro with OXLion. When I try to turn on the computer, the startup noise and screen appear (grey loading screenwith apple icon). A loading bar at the bottom of the screen fills about a third up, then the computer shuts down again.
View 2 Replies View RelatedThis morning, I would turn it on and it'd go to the grey screen with the Apple logo for a few seconds and then go to the icon that is a circle with a line through it. After reading online, I was able to boot it up in Safe Mode. I went to Startup Disk in Preferences. I chose the MAC OS X, xxxx and then clicked the lock to prevent further changes and then clicked restart. Now when I turn on the macbook, it goes to the grey screen with the Apple logo for at least two-three minutes and then just shuts off. Won't boot into Safe Mode now. I already tried the Command-Option-P-R keys trick like five times.

My new macbook aluminum's screen has a tendency to gradually dim and then brighten on it's own, randomly. This is off the battery power and not AC adapter. Anyone else's macbook screen do this? This is not the screen dimming to sleep. it is constantly dimming and brightening, even as I type this post.
