OS X :: CD Drive Wake The Screen, Turn The Led On But Does Not Show Anything?
Jun 27, 2009
i have had my macbook go to sleep an not fully wake up, the keyboard, cd drive wake an the screen would just turn the LED on, it brights up but does not show anything.i do NOT think its hardware, i believe the os is just not turining on the screen or speakers. it has done this 2 times an had to hardboot. before i hardboot it, i let it sit for a few minutes to see if it would wake up fully , an tried to close the lid again. also is there a short cut to restart or put it back to sleep so i dont have to hard boot. i dont expect to have this happen again , but if it does a key would be nice
After the computer has been in sleep mode for a little while, when i try to wake up the computer, it turns to a cray scree, a loading bar appears and then it takes like 5 mins for the icons to appear and for the mouse to work!

My Macbook doesn't turn on, it just show a white screen and after a while a big question mark blinks but nothing else, cannot click the question mark, cannot do anything.Also it makes a funny noise.
Is it possible (probably with a defaults write command) to have Mac OS 10.6 show a list of users on wake from sleep instead of a username and password window? I would like for users to be encouraged to use a guest account when the computer wakes up.
Mac OSX v10.4 tiger disk full and now won't start up. It showed lines of adaptec warning: SCSI reset detected and keep coming up non stop. After force quite and now Mac OSX shows blue screen w/spin only; I tried to start with CD but disk drive won't open. How?
we changed the hard drive in my friends G3 800 but now when you turn it on nothing comes up on the screen. It will act like it starting up, read the cd a little than sit idle.
I have a Quad Core Mac Pro running Snow Leopard 10.6.4. I've been having this issue for the past couple of weeks. Basically I have my monitor set to turn off after after 15 minutes of inactivity, my Mac Pro is always on. After 5 minutes of inactivity my screensaver comes on and stays on until my monitor turns off. When I move my mouse to wake my monitor, sometimes an image from the screensaver appears onscreen for a few seconds and then disappears when my desktop appears.
I have repaired Permissions, rebuilt my drive using Disk Warrior, installed the 10.6.4 Combo update but the issue remains. An image from the screensaver doesn't always appear when I turn on my monitor, this issue is sort of random. Usually my desktop appears right away with no static image from the screensaver.
i want to know if there is an option or a hack that when i turn on my imac it will always show boot menu then i can choose mac or windows. Without always having to hold down the option key?
I found my dock is gone. When I moved my pointer over the edge of screen where the dock was, the dock does not show up. I went to the Dock preference, it seems that the option "Automatically hidd and show the Dock" is chosen. I turned it off. It shows no difference. And I went to the Dock preference again, the Option is still chosen. And the Mac->Dock-> Turn Hiding Off is not functional. And also the hot key combination. Now I have to went to the lunchpad to see my dock and all my applications. It is really annoying.
How do you turn off Show Desktop (Push All Windows Aside) on a iMac when using a mouse, I know how to do it on a MBP but I can't find anything in preferences on an iMac
Just got a new Mac pro and installed an SSD as the boot drive. I was downloading some apple software updates and left the machine alone to download for an hour.Came back and it was asleep or hibernating (is there a difference?)At that point I clicked the mouse and I could hear it start back up but NOTHING came on the screen, just black.I could press a key on the keyboard and hear the error type noise so the desktop was active, just not being displayed.
I disconnected my mini display port (I have a 24' Apple cinema LED display) and plugged it into the second mini display port on the back and it came back on.Anyone know what this could be?A result of an SSD boot drive or do I need my LED display plugging into a particular mini display port out of the 2 on the graphics card?
I have a MacPro 1,1 (2006) 2.66GHz that it is always working as a home server.
After some time working idle the screen goes black. When I want to wake up there is no response. The screen turns into safe energy mode blinking his LED light power indication. I have to force shutting down pushing phisically the power button for some seconds.
Graphic Card problem? I have another one but I don't test it for now.
I have made a PRAM reset and SMC reset shutting down the MacPro, unplug the power and push the power button for 10 seconds. No results at all.
Even putting Energy System Preference on NEVER (computer sleep and screen) after some time (2-3hours) the MacPro goes to black screen.

I have a MacBook Pro. Sometimes my macbook might fall asleep while opened, and when I try to wake it up it doesn't respond.. I can see the backlight on the keyboard light up but the screen isn't responsive? My only solution when this happens, is to restart my MBP.
When I wake from a long sleep, my screen comes on but everything is black. If I move my mouse around, the tiles behind the pointer switch over to whatever app is open. When I invoke expose/spaces, the screen fixes itself and displays everything.
I'm on Mac Pro os x 10.5.4 and having a problem with my computer waking up from sleep or as it is booting up.
As it wakes up from sleep, the screen becomes blank or shows weird, pixelated bars all over the screen. When I try to move the mouse or press something on keypad, the computer freezes after and I would have to force shutting it down by pressing the power. It doesn't always happen, but quite often these days.
Also, when it's booting up, it sometimes will freeze with a blank screen in the middle and won't show the desktop.
Everything worked fine until a few days ago, and i'm wondering what's suddenly causing this problem.
This has happened 2 times (rarely). Basically, when I wake up the macbook pro, the screen would remain "blank". I know the screen is on because I can see the mouse pointer but the whole screen is black. I'm assuming Finder has crashed?
I don't know how to restart on the macbook (ctrl + alt + del didn't work, using option didn't either) so I just held down the power button for 4 seconds and restarted that way.
After my 27" i7 wakes up from a long sleep (roughly over 1.5 hours), something very odd goes on with my color profile and/or screen. Approx. 5 second or so after waking, the screen color appears to wash out quite a bit. You certainly have to be quick to notice it, but something is definitely going on.
Just bought a new 15" Macbook a few days but I have a serious problem. Every time I conntect it to my HP x2301 (also brand new) with a minidisplay > DVI cable and the Macbook goes to sleep the monitor won't take up after I wake up the Macbook.
My screen on my 2 week old iMac comes up pixelated leaving square trails mimicking the movement of the mouse. I have had consultations twice with Apple support junior team members, looking forward to a senior team member reviewing my case. It looks like some sort of eraser wiping the blank dark screen revealing the login screen underneath.
Oh by the way my first iMac was sent back due to dead pixels, how unusual is that?

I slept my MacBook Pro last night and can't wake it? I have rebooted and no bing sound is made. The screen remains black. The volumn keys blip. It is as if it is still locked in sleep mode!
This just started yesterday (May 31st). I keep everything updated as it comes out and nothing new has been installed in the last couple of days.
When I need I wake up my iMac (now requiring a keystroke or mouse press instead of just moving the mouse), the screen comes up black, but the cursor is there and moves around fine.
It stays black for a while (15 seconds or longer, but it feels like forever) and then it finally comes up completely.

My daughter has dropped her ageing MBP, bent the screen lid and now the screen is no longer usable. We have other Macs available to access the data on the screen if we could turn on Screen Sharing on the damaged MBP running Snow Leopard.
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.
For the past few weeks it has been going to a black screen when trying to wake it up from sleep. Either I've put it through too much work lately editing all these photos and its really tired. So, often it wakes up normally and functions fine, well, not really. It is seemingly very slow. It requires a lot of time (more than before) to open up a program or it gives me the "spinning wheel of death" when trying to go to a different page on the internet or open up a folder on my desktop. Amongst other things that require it to think. So It's just a lot slower in general than before.
In the last 2 months or so, I have seen my MacMini 2011 OSX 10.7.3 crashing withing a minute of wakeup, after sleeps of more than 2-3 hours.
Sometimes the Black screen occurs almost immediately, sometimes it takes up to a minute after the desktop appears (after logging in). This did not occur until I got 10.7.3 and only within the last 2 months.
