When I run the SMC 1.3 update, my computer just stops at a black screen, at which point I have to force shut down the computer and restart it. It then informs me that I need to run the update again.
View 1 RepliesComputer 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.

Is there a way to get my screen to turn on remotely from my imac?

I installed 10.7.4 update and now my screen goes black. It is quiet random at times, but mostly goes black after a few seconds from wakeup. Pressing the space-bar restores the screen, then sometimes it goes black again almost immediately.
Anyone else having the same problem?

About 6 months to a year ago, I had water damage onto the macbook pro, it completely didn't work for ages, however yesterday I thought I might as well try it again, and it worked! I was super happy that the laptop worked completely fine!Â
However, in system properties it was only saying it has the intel chip, not the nvidia one, so I thought maybe the graphics card was broken from the water damage? I was not too sure.Â
I then went to upgrade to mavericks, as soon as the update finished, black screen! From the second I turn on the notebook its black, no cursor no nothing, the PC turns on fine, I can type my password, then search for itunes, hit play on the keyboard and music plays. So its literally just a pure black screen. I try to hold CMD-R when restarting the notebook and nothing, pure black screen the screen never comes on at all!Â

I was BBMing while trying to plug in my headphones with my pheripherals, and I accidentally pushed it (not very hard) into the USB port. The tip of the headphone jack connected with the little connector ball at the bottom of the USB port. The screen went black and I instantly hit the power button on instinct, so I don't know if it shut off. Did I do something very bad, or is that normal? I'm not sure if that's even considered an electric shock or what.
View 3 Replies View RelatedEverytime I turn it on I get a black box asking to shut down or restart the mac. I have managed to get it to turn on to powersave and managed to update the software. Thought it might help but just made it worse - it won't boot up at all now past an apple symbol with a little swirly thingy underneath (I apologise now for my lack of intelligence when it comes to computers/knowledge/names of things!) The first time I managed to boot the computer up it came up with the grey screen and a little folder flashing between a face and a question mark which I assume meant it couldn't find anything but that appears to have gone away now. I bought this computer new from Apple about 2 - 3 years ago and no disks were provided with it.
View 3 Replies View RelatedWhen I open my macbook, the screen remains black (as though it's in sleep mode). Adjusting the brightness always fixes this problem, but this is a temporary fix. The brightness is not at zero when I adjust it after opening, often I need to dim the screen to reactivate it.
This problem is not: related to *clamshell mode*related to unintentionally dimming the screen. related to any of the settings in the Energy Saving panel in system preferences
Extra info: The computer seems as though it doesn't actually enter sleep mode when I close the computer.I don't think there are any processes running that would prevent sleep mode. I really just want the computer to go to sleep properly when I close the screen and more importantly, that it wake-up when opened, or at least when a button is pushed aside from the brightness buttons.

I just bought a macbook pro, and I installed bootcamp and had everything running perfectly. I installed the drivers, and then I let windows 7 update while I went to sleep, when I woke up the macbook was turned off, then I tried to turn it on, and it sounded like it was about to boot up, but the screen is blank there is no cursor, it looks like it's not even on, and I think the keyboard is unresponsive because when I press caplocks it doesn't light up.
View 1 Replies View RelatedI 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?

View 8 Replies View RelatedMy macbook is running Mavericks OS X 10.9.4, and I'm having difficulty getting rid of the vertical black columns on my computer screen when it is connected to my classroom projector. I've played with the resolutions, and the best resolution for the VGA display is 1024x768...Unfortunately this creates less than desirable black columns on my computer screen. Another teacher in my school has display settings of "1024x768 stretched," and her macbook does not have the issue mine does. However, I don't think she is running Mavericks 10.9.4. I cannot find this display option on my computer.

I have a 27 inch desktop. Upon turning the computer on within seconds the fan comes on. Then it goes to a high fan. Then it goes to a black screen. Then it shuts off. Then if you click the mouse it will come back on. This cycle repeats itself every 5 seconds. Only one time in the past month did it turn on normally and run for me.

I got my computer yesterday, it's a iBook G4 OS X 10.5.8. The charger worked fine until around six o' clock. Then it wouldn't charge. We switched the power pack and it worked for an hour or so, and then the same thing. What can I do? I CANNOT take it to be fixed.
View 4 Replies View RelatedEvery once and a while, usually when my MacBook is running on it's battery, the screen will show a black screen for nearly only a millisecond or two. It's not too bothersome, and it usually blinks back to normal before I can notice it, but nevertheless I don't want it, and from what I can recall, this only started happening after I installed the Snow Leopard Graphics Update. Is anybody else getting these problems on their MBPs or MBs? MacBook config details in my sig.
View 4 Replies View RelatedI have been experiencing an issue with locking my computer screen ever since updating to 10.6.3. Normally, when I choose to lock my screen through the Keychain Access menu bar item, the password prompt will be displayed over a black background. However, since the 10.6.3 update, sometimes when I choose to lock the screen, the password prompt will simply be displayed over my actual desktop, and the open windows, menu bar, and the dock all remain visible. I updated to 10.6.3 using the combo update package, and I have tried repairing permissions and resetting the PRAM and SMC to no avail.
Console displays this error message:
loginwindow[38]: ERROR | -[LWScreenLock(Private) screenIsLockedTimeExpired:] | Error: _startLockTime = 0
I downloaded Mac OS X Snow Leopard on my desktop and computer restarted correctly. It then prompted me to update the printer software. There was an error. I continued and computer restarted and now the screen is white withe Apple emblem and circle continuously runs below. I have tried restarting the computer but this is the only screen that comes up.

just ran a recent update for my macbook pro/mid 2010, and the computer just woke up with a plain blue screen & spinning beach ball - I had to do a hard shut down.I am also having the problem of having my screen going black for a couple of seconds, I read up on it in Support. But I was wondering if there is something else going on.

I've noticed after upgrading to 10.6.5 that my keyboard will not work when I come back after an extended period of time away from the machine. At first, after applying only the 10.6.5 update, neither keyboard nor mouse would work unless I unplugged and replugged the keyboard (the mouse is connected directly to the KB). Later, I installed the combo update, and then the mouse worked but the keyboard still wouldn't. This is after my display sleeps - as long as I continue to use the computer, everything works fine. I have a mid-2009 Mac Pro 2.66 GHz quad-core (Nahalem) but with the older (clear, G5) keyboard and a mighty mouse.

When I am doing an update software for my OSX 10.6.8 the looking for update bar only goes about 1/3 across the bar then stops and idles with the blue lines still moving. This happens on both Firefox and Safari. Is the apple server busy or is this a sign of the flashback trojan horse?
