Software :: Mac Pro (2008) Black Screen When Idle?
Jun 30, 2009
My Mac Pro has started to go to a black screen when idle for a period of time. When it does this, I need to use the power button to power off and restart. It does not appear to be asleep (I have it set to never sleep) since Time Machine is still backing up and Mobile Me is still syncing. Oddly, if I manually put the computer to sleep (under the apple), it will come back to the normal screen by using a key on the keyboard (moving the mouse does not work) no matter how long I am away.
I have tried resetting, disconnecting and reconnecting all cables but the problem still exists.

I'm having a bit of a problem with my Macbook. Once the display goes to sleep, I can't seem to get the screen to come back. The computer doesn't actually turn off, but when I try to get it back with my mouse it goes black. I can usually still slightly see my applications and stuff, and the fan still runs. I end up having to shut it down and then restart it every time. Just wondering if anybody knows how to fix this.

Recently my Mac Pro has been going to a black screen when idle for a while and I need to power off using the power button and restart. It's not set to ever go to sleep but if I use the sleep function under the Apple, it functions as it should, waking when I touch a key (although I don't let it sit for a while before I wake it). When it is in the black screen mode, it still is performing Time Machine backups.

I recently purchased a refurbished 24 inch imac from the noticed when the computer is idle (black screen), my wired mouse does not work. When I pull the cable out of the usb port on the imac, the computer screen comes on and then I reinsert the cable back into the usb port in the computer to use the wired mouse (wired mouse works fine after I reinsert the cable back into the usb port).Could this problem be associated with the wired mouse or with the usb ports on the imac?

My 24" 2008 iMac screen keeps going black then coming back after a while. What temperature would it need to get to in order to knock out the display? I have iStat.Also, if the screen fails due to graphics card or other component, is it possible to connect an external display to use it until I can upgrade to a mini?

I left my laptop on in my room while I went to the bathroom, and when I came out, I saw the message that told me I must restart the computer. The message froze the computer, so I shut it off by holding the power button and tried to turn it back on again, but it only boots to a black screen. I don't hear the loud hard drive noise, but I hear the fans. Without AC power but with the charged battery, the computer shuts down after a few seconds. The light on the button that opens the lid is dim-to-none when the lid is open and bright when the lid is closed.
I tried many troubleshooting methods discussed on this site, like removing and reseating the RAM and draining the battery, along with the things that the Apple website suggested, like resetting the SMC and PRAM, but nothing works.
I brought the computer into an Apple Store, and after the NVIDIA test was negative, the technician told me that the problem is most likely the logic board. I also took the computer into an Apple Authorized Service Provider, and the technician there said it could be the logic board, hard drive, or boot connector. He also said that there is a very slight chance that the graphics card could have caused the logic board to fail. He tried my computer with another battery and concluded that it's not the battery's fault.
The Apple Store is charging me about $330 for a flat-rate repair. Should I troubleshoot further using suggestions you may have or pay Apple for repairs? If I decide to have Apple repair my laptop, do I need to take it back into the store to pay the repair charges, or can I do it over the phone and mail the computer to Apple?

I have a 2008 MacBook and it was working perfectly fine until one day I was using it and the screen instantly faded to black. I first thought my battery power had shut off, so then I closed the laptop but that little light on right front side was still blinking meaning the computer was still on. I then shut down the computer and turned it back on but as it started the screen was its normal brightness for about 3 seconds then it quickly went black again. If I shine a light on the screen I can barely make out what it shows, which is my normal screen when I open up the laptop. Did my screen somehow break from overuse or does have to do with the battery?

I have a problem: when I restart my Early 2008 MacBook Pro there is no "chime" and the screen remains black. The keyboard doesn't light up or respond to any input, and worse still, the "lid button" light on the front of the notebook remains illuminated, it doesn't blink, it just stays on, shining in my face. I loaded a CD into the optical drive to see if I could use the keyboard to eject it, but this test failed. Now, when I turn on my MBP, I hear the optical drive spinning and the quiet whirr of the fan inside.
I looked on Apple's support website about what to do when a Mac refuses to boot. I tried all of the methods they listed, but since my Mac doesn't respond to keyboard input, all of the techniques failed. Having exhausted everything I could think of, I decided to post here hoping someone could suggest something. I was just on the verge of completing my portfolio website and I would like to salvage my data at least.

Whenever I use something cpu/graphic intensive, the temp shoots up and stays up. Normally I would idle at around 36C, but after I use youtube or play any game, the temps would stay at around 55C even after exiting all the programs and is at 99% idle. It's fine when I'm plugged in, but when I'm using my battery, I only get about 2.5 hours with the brightness on very low and wifi/bt off. Checking the stats on iStat, the battery is using 19Watts at idle.

Whenever I turn my computer on, it makes the start up sound and acts like the screen will turn on, then it goes black. I can't get it to come out of sleep unless it goes idle. It's like the roles have reversed. The screen turns on when idle, but as soon as I move the mouse or touch a button, it goes black again. It's plugged in, and even if the battery is dead, it always runs when it's plugged in. Also, on the battery bar, it's stuck at 00:26.

I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?

I am looking at purchasing an Ibook G4 but the description of the item includes this:"When you switch it on it begins to load up i.e. the blue screen with the Apple logo, but then the screen goes black or flickers. Said friend has kindly wiped the hard drive for me so now when you switch it on it makes the �opening� noise then you get a blue screen with alternating �?� and the Finder logo."
I have a feeling this may have been a temporary fault with the screen connector being loose and possibly damaged.But i assume the alternating "?" and the "finder logo" is simply a lack of OS?

I was trying to install Windows XP Pro, but for some reason the it wasn't showing another HDD to install Windows on. So I quit the install, and restarted my computer. Now all that happens is the normal grey screen appears (with no Apple logo), then it goes to a black screen and has the blinking cursor (Kinda like DOS).

So I have a DYNEX 21 inch HD TV conected up to my MBP via the VGA connection route. My problem is that when I want a program (or more specifically in this case a game) to go into fullscreen mode it automatically goes to my primary monitor and turns the other screen black. I know I can switch the primary monitor from my actual laptop screen to the TV however I just want the game to be full screen on the TV while still having access to my dock and everything on my laptop.

I have a problem with my screen - when there is something black on, I can see a faint mark of a lighter colour. I have tried to take a picture, please excuse the poor quality. There is nothing visible when the screen is off, even under close examination. Is it less visible when lighter things are on the screen, and invisible when the screen is white.
No drops or liquid spills. Will this go away on it's own? Any fixes?

My iBook will not display anything on its screen. Rather, it just remains black. One time, the screen did come on, but then shortly after booting, it flickered a lot and then went black again. A year ago, something similiar happened and when I took it to be serviced (when I had AppleCare), they had to send it away and have a new logic board installed. Now this machine is out of warrenty and and I am not sure what to do, or even if it is the same problem. Any suggestions?? Thanks!

As the headline says the right half of the screen turns black when watching video content in iTunes on full screen. I can see the whole picture when moving the mouse a little but as soon as the navigation bar disappears the right half of the picture disappears too. It does not matter what source it is. Both podcasts and movies work (or do not work) the same.
The problem doesn't occur for other player (VLC, XBMC etc.).
I have the latest OS (10.9.4) and iTunes (11.4). The computer is MBP 13-inch retina, late 2012 if it matters.

I've had my mac for about three years now and everything was working fine. After I installed lion, I notice that this started to happen. I don't lose any of my information though when it does that. It just goes into a sleep mode I guess? Anyways, is this a feature from the lion update? Something standard?

New to Mac computers. When trying to open computer after being in sleep mode, I clicked the mouse to open the password screen, & a blank blue/black screen appeared & the mouse timer( colored circle) appeared, as if to be waiting. I had to unplug the computer to reboot it. This has happened twice in 2 days.

When my MacBook Pro 13" i5 goes into screen saver mode, which is black, it won't return to normal mode. Tried all keys, trac pad, closing the lip and re-opening it, and it won't respond. The only thing that works is holding down power button for hard shutdown, then restarting it. It has happened 8 times in the last 2 weeks.

Computer starts (keyboard lit, music plays, caps lock light on), but no screen. I need to open and close 2 - 30 times before the screen will turn on. Once on, the computer works perfectly. I've tried PRAM and safemode reset.

So last December my laptop got smashed and everything works except for the backlit screen. In fact I can still use this laptop it is just extremely hard since the screen does not light up. The person that smashed it ended up buying me a new laptop so I have this beat up (and I mean the shell is destroyed) laptop with quite a lot of functioning parts.
Now a few weeks ago my girlfriends Grandad spilled a beer on his brand new 2010 Macbook. The logic board is shot so it is almost cheaper for him to buy a brand new laptop.
Would it be possible for me to take the logic board out of my 2008 Black Macbook and put it into his 2010 White Macbook?

when I turn on my computer there is a blank screen. You can still hear the normal noises coming from the computer like any normal boot-up. But if I let my computer sit for a while without turning it on, it will turn on with weird almost static noises. If I force shut down then try again, I get the normal boot-up noises. I tried the safe boot-up method,holding down the shift button while turning the computer on, but no dice. I actually tried this method on both the good and static noise boot-up.
