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

Hardware :: Computer Switches Itself Off - Getting Gray Screen

Feb 19, 2010

I have a 20" iMac G5 1.8 GHz which has been pretty reliable since new. A few weeks ago I fitted a new Hard-drive (Western Digital Caviar Black 1TB), other than that the computer is bog standard. For the last few days when I start up, the computer switches itself off straight away and I have to press start again. Sometimes it gets as far as the grey screen and sometimes it gets to a complete desktop screen before this happens. This may happen 2 or 3 times and then the computer works fine all day, I can even restart with no problems once it is running fine. As it stands I can live with the problem but I worry that it may get worse. Anyone know what this might be? Could it be related to the new hard-drive? Could it even be related to the cold weather?

While working on the computer, sometimes the screen will turn gray (from top to bottom) and a message will appear saying the computer must be restarted.So far the local Apple store has not been able to find the problem. The last solution the store tried was to replace the Airport Card, but that didn't work. Computer was purchased in December 2011.

MacBook :: Computer Crashed - Greeted Upon Start Up With Gray Screen

Jun 10, 2010

Allright so my girlfriend accidentally spilled a drink on her macbook the other day. We thought we had cleaned it off and everything was fine. We were mistaken. During normal usage the computer crashed so we restarted it and are now greeted upon startup with a gray screen and a gray application folder with a question mark on it flashing repeatedly. What is the course of action guys? I'm not computer whiz and I'm wondering if we can fix this ourselves without having to take it in for repair. And FYI she does not have apple care

Desktops :: Computer Boots Without Showing The Gray Screen With Apple Logo?

Mar 2, 2010

I'm noticing some weird behavior in my Mac Pro first gen.

Basically, when I start it up, the displays just stays black for some time, until the Desktop loads up and the computer is functional, but never displays the gray screen with the Apple logo. This just happened all of a sudden and stayed like this.

I know is not a big deal now, but I'd like to sell it in the near future and this could be problematic for that.

MacBook Pro :: Computer Starts With Gray Apple Screen Then Turns White

Sep 29, 2010

I am trying to fix a friends macbook pro. When I turn it on the screen shows the apple and the spiral underneath it spinning like it should then when it stalls for .2 seconds it goes to a white screen then there is vertical purple lines in groups across the screen. So the screen is white/purple. Then it fades to just white and I cant do anything.

I hooked up my monitor with a DVI cable to see if it was the motherboard that was possibly bad but the monitor works just fine with the cable. I can use the computer with the laptop keyboard/mouse and it works just fine. The laptop screen just stays blank the whole time. I uploaded a vid to utube for it. If anybody has any ideas for me please help. I dont know if this is a monitor problem or the inverter or the motherboard, possibly some other piece of hardware?

I got a 3 year old white macbook. I was surfing the net when suddenly it turned off. On restart, I got the grey screen for a while, the a picture of a file with a question mark in it, waited for ten minutes, still the file. I have done the following:

2.- Use the option key on startup: I get a grey screen with the curso on it, which I can move with my mouse, but no buttons to click or nothing.
3.- Use the X key: as if doing nothing
4.- Resseting the SMC: as if doing nothing

PowerPC :: Unable To Boot Powerbook / Gray Screen Turns Computer Back Off

Nov 1, 2006

So I've got a powerbook G4, thats 8 days past its warranty. Conveniently, it now won't turn on. It won't wont boot from CD. If I turn it on, I get a gray screen that usually just turns my computer back off, if thats not the case I get a screen that shows the finder icon and a question mark and then turns off.

All it will do is boot into open firmware mode. Currently the install disc is inside of it and I've tried booting the cd using "cd:, bxi" and "dir hd", and it can't open both. Does anyone know how to wipe the HD, and start the installer using firmware? Otherwise, I think I'll have to take out the harddrive and plug it into an external case and then wipe it.

OS X Mavericks :: When Searching A File In Computer It Doesn't Show Location Of Folder

Dec 9, 2014

When I search for a file in my computer (command + f) the results appear in a window. If I click on a FILE among the results, the detailed location of that file is shown at the bottom of the window. If I click on a FOLDER, however, no such location information appears. Before Mavericks, locations of folders was also given. Is this a Mavericks bug? Can it be fixed?

OS X Mavericks :: Gray Screen After Erasing Hard Drive And Resetting NVRAM / PRAM

Jun 17, 2014

I have a mid-2011 iMac (with Mavericks OS), and am doing a clean install before giving my computer to a relative. I performed a secure erase of my entire harddrive (using disk utility), reset the NVRAM / PRAM (but it only chimes once even after I tried several times), and now I get the grey screen even when I try to boot from CD, safe boot, or any other commands. I can't even get back into the disk utility.

On a side note, I have the install DVD in the DVD drive and I can't get that out.

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.

Power Mac G5 :: Computer Won't Wake Up

Oct 25, 2007

If I'm away from my computer for awhile, it goes to sleep and won't wake up. Hitting Return or other keys won't help; nor does pushing the Start button on the back. The only solution I've found is to unplug the computer, re-plug, then start again.

Intel Mac :: When Computer Goes To Sleep It Will Not Wake Up

Feb 1, 2012

When my computer goes to sleep it will not wake up, and I have to shut down using the power button on the back and then restart. I called support and they advised me that this only happened when the computer went to sleep on it's opwn but not when you manually put it to sleep, But that proved not to be true.  It will not wake up under either situation?  The support persontold me to logonto applke and re-install the sytem software which I have done but that did not cure the problem either. I have my preference set to never sleep. I am ar]t a loss as to what to do now as when it goes to sleep or I put it to sleep i sometimes will not start up even after shutting down and restarting.I am on 10.7.2?

Mac Pro :: Added Second Monitor Computer Won't Wake Up

Apr 11, 2012

I have reviewed several support threads on the subject of a 2008 Mac Pro not waking up after it goes to sleep.  I have a 2008 mac pro that was working flawlessly with a 26 inch asus monitor.  My bluetooth mouse and keyboard would wake it up instantly.  I decided to add a second monitor, a 27 inch planar. I had the mac set up to save power and after just five minutes of non-use it would go to sleep.  My wife asked me if I would keep it on longer so she could watch the pictures that show up through the screen saver so I set it to 15 minutes and then it goes to sleep.  Now though, if it goes to sleep it won't wake up and remote connections from an imac fail to awaken it as well.  I am forced to hold down the power button to shut it down.  I have tried the startup where I hold down command option p r but I can't get it to sound a second chime whether I start after the first chime or before the gray screen appears.  After trying this every other restart does not work, the fans turn on but nothing else happens.  It is quite odd.  I am at my witts end.

IMac :: Computer Goes Into Sleep And Wake Up Automatically

Dec 15, 2009

I had my iMac 27" for two months, and I am very pleased with the machine - except for one thing. When I put it to sleep, the computer just go to sleep in a couple of hours and then return to no-sleep. It started just after I bought the computer. I always set my computer to sleep, and so I did even then - but the first thing I noticed was that the hard drive was started during the first night. Strangely, I thought and put it to sleep again. Then I fell asleep, but when I woke up next morning the computer was on.

Then I wrote on another forum and they told me to check out: Wake up in network access, which I did. And then it got better. Now the computer has been without problems for a month, but then a few days ago it came back. This box is still check, so it can not have anything to do with it this time. I've also tried turning off all programs, the keyboard and mouse when it has gone down to sleep, but it still restarted. What is wrong? Please run with Sleep and it is a program that will prevent the computer to wake from sleep, but not:

2009-12-14 00:12:00.870 Please Sleep [8574:207] Sleep notification received from the system

2009-12-15 05:22:18.061 Please Sleep [6883:207] Sleep notification received from the system
2009-12-15 07:27:34.597 Please Sleep [6883:207] Wake notification received from the system

What can I do? Can I submit it to Applecare? Some peoples say you do not have to turn off a Mac, but I want to put it to sleep, but it starts up the next day. I've also restarted the SMC, but it gave no effect.

OS X :: Monitor Wake Up With Screen Saver Image On Screen

Jul 15, 2010

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.

OS X :: Require Password To Wake Up Computer Takes Time

For work, I got a new MBP 15" a month ago and we have the computer set to require password to wake computer/screensaver. When I type in my password, it sometimes takes up to a minute for it to authenticate the password. Other times it takes a second like normal. I check the error logs and nothing is coming up during those times.
