30" display doesn't wake

Hi, I've had a 30" display for a month or so. One issue: When I leave my computer and it switches itself off, sometimes I can't switch it back on, either by moving the mouse, hitting the keyboard or the power button on the side of the monitor. I've been reduced to switching the mac off and on at the power switch.
Last time I did that, I managed to trash Entourage. (Don't worry, all backed up).
Still, it's annoying.
Is there a workaround for this?

My 23" has been acting in a similar way the past couple of weeks...and seemingly out of the blue! When I power up the G5, the power LED on the display will come on briefly, but then go off.
And, the USB ports on the back of the display are non-functional at startup. I have my keyboard and mouse plugged into these ports, and when I plug them into the front of the tower instead, they work. Still, even then, the display itself won't come on.
The funny thing I've found is that I'll come back to the computer a while later and the screen will be up and functioning, USB and all. This makes me think it has something to do with the display sleeping while the computer is on. Perhaps it's a power supply issue? Hopefully it's the display and not the tower. I'm hoping it's an easy resolve.
Is any one else experiencing loss of USB functionality on the display at startup?

External Display doesn't wake from display sleep

My display is set to sleep after an idle period (computer itself set to not sleep), when I return to the computer and wake the displays the external display most of the time does not "wake" or come back with picture. I need to disconnect the adapter and plug it in again.
Anyone else experiencing this?

Guys, please read THIS thread:
http://discussions.apple.com/thread.jspa?threadID=1760586&tstart=0
EVERYONE is experiencing this bug if you're using your new MacBook Pro with an external display. In the thread above, I detail how to fix it without having to unplug the DisplayPort adapter.
The symptoms you're experiencing are:
1.) Bizarre interference all over the external display when either a) waking your notebook from sleep, or b) turning screen on if the screen is set to turn off after x minutes.
2.) External display not actually turning on at all after either a) waking your notebook from sleep, or b) turning screen on if the screen is set to turn off after x minutes.
The fix is listed in the above thread. It's only a temporary workaround, and Apple REALLY needs to address this issue ASAP.

Display doesn't wake up after going to sleep

On rare occassion, but often enough to be a hassle, my 20" apple display will stay black after I move the mouse or hit the keyboard after the computer has gone to sleep. My only solution is to hold the power button in for 5 second and force a restart. Why does this happen and what can I do to stop it?
Thanks!

If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
Restart your Mac and immediately hold down the Command-Option-O-F key combo until you see a somewhat intimidating command-line display that ends with the Open Fimware prompt. Type the following line:
reset-nvram
press the return key on your keyboard
set-defaults
press return
reset-all
press return
Your Mac will reboot. Once it's running, put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong.
Still did'nt work? Might be time to call AppleCare or see an Apple Genius or a technician.

Norm,
I to am having the same issue. In fact, not only does my computer not wake up but the fans turn on full speed and wont go off.
As of this posting I have been on the phone to APPLE TECH for 1 hour. Tried many different 'fixs' with no results. I have been instructed to call back tomorrow and continue with a 'higher up' techy.
I'll post what ever the Tech results are at that time. Hang on a little longer.

Display sleeps but doesn't wake on click or tab

Hi,
I have a Mac Mini(mid 2011) with came with Lion. I just upgraded to 10.7.2 and since then there is an issue with the sleep function.
I have not put the mini to sleeep as i keep downloading large files or converting movies but the DISPLAY is set to sleep in 10 mins.
IT was all fine but ever since the update, the display doesn't wake up once it goes to sleep. Even though i click the mouse or press keys on keyboard.
A black screen prevails on the screen and the viable option left is to cut the power off and restart to access the screen. It is seriously hampering my ongoing tasks as they are closed abruptly.
For the time being i have set the display to never sleep. But i am looking for a solution. Has anyone else also faced the issue after an the update. Any suggesstions would be highly appreciated.

MacBook Pro (17-inch, Early 2011) doesn't wake the thunderbolt display after sleep

for some reason the display when connected to clamshell macbook pro 17" doesn't wake up when i go to wake up the display from sleep mode.
what is going on?

The other day I got the blue screen, the fan going on high, and then when I disconnect my thunderbolt connection from my macbook pro - i get a shutdown.
Today I got flickering followed by the fan on high and then again I disconneced my thunderbolt cable and after a minute or two a shudown.
This never happened before. Actually I was suprised to hear about a firmware update for flickering since that's never happened to me but since updating I now get the flicker.
Any ideas?? Any help would be greatly appreciated as this is my work labtop.

A brand new Mac Pro doesn't wake up from sleep

I got a new Mac Pro.
It has an external SATA controller and a video card with NVIDIA Quadro 4000 chipset on it.
It has a Snow Leopard installed.
The problem it has is that it doesn't wake up once it goes to sleep, either by choosing "Sleep" menu item or by using "Energy Saving" setting.
I notice some people mention a keyboard doesn't respond while his trackpad does. In my case, nothing works.
I don't know if it is due to keyboard or a magic mouse. I tried to connect another wired mouse to the enclosure of the Mac Pro directly, but it did't cause Mac Pro wake up.
By searching on Google, many people seem to have this problem, whether they have Mac Pro, MacBook Pro, and so on.
Personally, I have a 17" PPC iMac, 13" MacBook with Core Duo 2, and have used MacBook Pro 17", but they didn't have this problem.
I tried to reset the SMC, but it didn't help.
Do anyone know what cause this problem and how to solve it?
Is there any patch for this?
Thank you.

Does it sound like it's waking up but the monitor just doesn't display anything?
I ask because if so, I'm experiencing the same problem. I have a Quad-Core Mac Pro (no external devices) and if it goes to sleep I have difficulty getting it to display anything on the monitor after waking it up. Now, I just recently hooked up an additional monitor (VGA) for dual display, and the funny thing is, that monitor will wake, but my main monitor won't.
Sometimes I get this error after boot-up too, where the computer will get to the login screen, but my main monitor is receiving no signal ("at least according to my monitor").
If that's the same issue, then I'll post any success I find for you!
Best,
J

Display won't wake up

It's a brand new notebook.I've done nothing on it, other than installing Windows updates and creating recovery disks.I set the "Turn off display after" option to 1Minute.IMPORTANT: I set display brightness all the way to zero, the lowest setting possible, using either the keyboard keys, or the brightness option in Windows.Leave the notebook idle for a minute, the display sleeps like it should (the notebook is set to sleep after 30 minutes, it's only the display that sleeps, the notebook is still awake).Move the mouse, press keys on the keyboard, the screen does not come back up. The computer is still up and running-i can toggle keyboard backlight On/Off using the keys, but the display won't wake up.Press the "Brightness +" button on the keyboard, the display wakes up. This is the only way to wake it up. The other option is to press and hold the power button, force a shut down, and start the computer again.This happens ONLY when "brightess" is set to the lowest level. If brightness is set to even one level above the lowest, the issue cannot be reproduced. Moving the mouse or pressing any key on the keyboard will wake the display up in this situation.Both Intel HD graphics 5500 and GTX 850M drivers are up to date.BIOS is up to date as well.Battery/ Plugged in does not make a difference. If the display brightness is set to lowest, the screen will ALWAYS fail to wake up, irrespective of which power source is in use. What do I do? Please don't tell me it's a minor problem and I have to live with it.There are so many minor problems with this notebook, and all these are adding up to make it a total piece of cr.. My almost 5 years old probook with a second generation core i3 CPU and no discrete GPU, is better than this brand new 5th generation core i7+GeForce GTX notebook. I'm beginning to regret this purchase. I should have gotten another probook. Thought the Envy offers a better "bang for the buck", and now i think this was a huge mistake. Anyway, any idea how i can get this fixed? Looks like a driver problem right? Or is this a hardware problem? Can someone with an Envy notebook try this out and tell me if the issue can be reproduced on their rig? It can't be reproduced on my Probook.Thanks.

Thanks for your reply Avenger Well, I called up HP tech support.The lady took remote control of my notebook and tried numerous things in the registry (regedit).But the issue could not be solved. She then arranged for an on-site support engineer to visit my house.The Engineer showed up right on the next day, and tried the following:- Updated ALL drivers, even the ones which were already up to date!Checked with my desktop monitor, the issue cannot be reproduced on the external monitor- the external monitor will wake up on moving the mouse, but the notebook monitor stayed dim (no backlight).Opened the laptop, took out the display cable, cleaned it with some solution he had, put everything back together- issue not resolved, external monitor wakes up but notebook monitor stayes dimmed. This is not the only problem I was having with the notebook, the other problems are:Battery would stop charging when the notebook is switched OFF, and the charger is turned ON and OFF a couple of times.The battery lock doesn't "click" in place, it slides automatically to the "unlock" position, it's loose.There's a dead pixel on the display. He offered me two choices: 1> Replace motherboard (to solve battery not charging issue), replace chassis (to solve the battery lock issue), and replace display panel (to solve the dim display + dead pixel issue). =======OR======= 2> Return the whole notebook back to HP, and get a new notebook (same model) in exchange. I picked option 2. We shared a cup of coffee, and the tech left (he was very nice and friendly). The next day, I got an email from HP, with a PDF attachment, asking me to take my laptop, along with a hard copy of the email, and payment invoice, to the HP store. HP store took my computer back, but they didn't have a replacement ready, they asked me to come after 7 days to pick up a new notebook (same model). I really loved my Envy. It's a very nice looking laptop. Hope the replacement I get won't have these weird issues. I'll update the thread when I get the replacement. Thanks for your help

After 10.9.3 update monitor doesn't wake up from sleep

I have an LCD connected to the Mac Mini via a mini-DP to DVI adapter and a video projector is connected directly at the HDMI.
The LCD is the "main" screen while the projector is only switched on for watching TV or movies.
My "Computer sleep" is set to "never" and "display sleep" to 15min.
All was working well until I updated to 10.9.3 ...
Now, when the LCD goes to sleep (projector is powered off) it doesn't wake up any more.
The computer is running and it is responding to my key-presses etc. but the monitor remains in a coma.
Powering the monitor off and on again resolves the issue, e.g. the display shows correctly.
This is however only a temporary fix as it refuses to wake up upon the next sleep...
The monitor itself is fine, it works on other systems flawlessly, e.g. on an older Mini.
Any ideas?
I have already force-fed it with the combo-udate but that didn't help.

My iphone 3GS does the same thing, not only does it suddenly fail to wake up from sleep. It just crashes and I have to do a hard reset. Today it just turned off when the ipod was playing I was a mile away from it and it was in airplane mode as well. I have restored from backup once and would dearly love to have it downgraded but that doesn't seem to be much of an option. My phone ran like a dream before the upgrade....now I hate to say it but its completely unreliable.
With so many people experiencing the same problem it makes me wonder why there isn't a fix.

The Lamp of My Display Doesn't Blink Anymore.

I use the PowerMac G5 Quad and the 20-Inch Apple Cinema display. My display lights up while the PowerMac sleep or shut down, but the lamp of the display doesn't blink anymore. Does anyone have any ideas? Please, help me.

Thank you for your reply.
I had been using it without connecting the USB and Firewire cables, but it had worked normally for several months. I have connected both of the cables to the Mac, and checked the checkbox of "Puts the system to sleep or wakes it" in the Display options in System Preferences, and now it blinks when it is sleeping.
But... it is a little strange compared to before... Do you think this is normal?
http://homepage.mac.com/applmc/display.mov
However, it doesn't blink in any of the following cases.
— When I check the check box of "Turn the display on and off" in the Display options in System Preferences, and make it sleep, the lamp of the display doesn't blink, but it lights up.
— When I check the check box of "Does nothing" in the Display options in System Preferences, and make it sleep, the lamp of the display doesn't blink, but it lights up.
It's very weird. Maybe this is a hardware problem?

NEW iBook and doesn´t wake up after sleep mode!

Hi,
I´ve just started to use my new iBook G4 3 days ago, added my user information, and for a little while the wireless internet connection. Then, I closed the display to put it on sleep mode.....and.............it DOESN´T WAKE UP!!!
The hard disk seems to start up correctly (the fan is on and the disk noise is ok), the Caps Lock on the keyboard is on too, but as soon as I reboot the computer, a strange beep (like a phone tone!) starts up, then the sleep light signal flashes but the screen stays black.
I think that by now I´ve tried the most solutions (as far as I can having the black screen) I´ve read on the troubleshooting page and the recommendations posted in this Discussion chat... The iBook remains partially dead.
Help!!!

ummm, even when its not plugged in to the power adapter? i find that when my ibook annoyingly doesnt wake from sleep, its usually because i connected/disconnected something while it was sleeping. even plugging in the power adapter seems to affect it. the way i fix it is to put it to sleep again, and then open the lid. its worked every time so far.
oh, and apprantly 'manually' putting the ibook to sleep does the trick (ie from the apple menu)

Apple TV (gen 3) sometimes doesn't wake up

I love my new Apple TV! The video quality is unreal. The other night I rented The Girl With The Dragon Tattoo and thought "I think I may never buy another Blu-Ray". But there is one small problem: sometimes it doesn't wake up in response to Remote app on my iPad or iPhone, which is how I usually control it. If I wake it up using the IR remote, it will then respond to the app. I never had this problem with my gen 2 Apple TV, is anyone else seeing this? It also seems to wake up randomly on its own, sometimes I'll be watching TV and see the LED come on.

I'm having the same wake up and flashing LED issue with my 3rd generation Apple TV (2012). Also the same as your scenario; my 2 generation (2010) does not display the problems. But it is more of a headache for me since having two little kids in the house, sometimes the Remote App is the only way we can operate it when the IR remotes goes missing.
I'm starting to wonder if it is more of a hardware issue than software, since both Apple TV are operating on the same iOS 5.0. I may try making an appointment with at a Genius Bar next week to be sure.

TS3274 iPad won't shut off. Display doesn't respond to slide motion.

Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for device to restart (no data will be lost).

T440s doesn't wake up from sleep

I got a new T440s about 2 weeks ago and sometimes it doesn't wake up after it goes into sleep mode. It gets stuck on a black screen and the mouse cursor is visible, but moving the mouse or pressing keys on the keyboard fails to wake it up. When this happens, I have to restart the computer by holding down the power button for 10 seconds. I am running Windows 7 Professional 64 bit and hybrid sleep is off. I'm just really confused because sometimes it wakes up perfectly and sometimes it doesn't. Thanks!
Solved!
Go to Solution.

Hi someotherguy, firstly thanks for your replies!
I'll try to document my issue a bit better.
My setup:
Thinkpad T440p
CPU: i7-4700MQ
OS: Windows 8.1 Pro 64 (Upgraded via STORE from Windows 8)
Display: FHD WWAN
Graphics: Intel HD4600 / GeForce GT 730M
Memory: 16 GB GSkill 1.35v
HDD: Samsung 840 Evo SSD (250 GB)
Power: 135W AC Adapter
Wireless: 7260AC w/ Bluetooth 4.0
External display: LG 23EA63V-P (LG 23 Inch IPS Panel @ 1920x1080)
Connection: MiniDisplay Port to DVI Adapter with Dual link DVI-D Cable
Power settings: Max Performance / Always On
Sleep: Never
Turn off Displays: YES (this is the issue!)
I have disabled hibernate
I have disabled fast boot
I have installed all latest Windows updates and Lenovo drivers.
Nothing to call out in device manager
The issue:
Since adding the external display, both displays intermittently (90%) fail to wake from DISPLAY ONLY sleep. The system does (*knock on wood*) wake from manual setting of Sleep. However, when the displays turn off after the allocated time, it seems like my system is in tandem assuming some sort of sleep state. It does not look like only the displays are sleeping.
Once the monitors turn off, moving the mouse or hitting the keyboard will initiate some system feedback (backlight only on laptop lights up with blank screen, fans spin up) but the external monitor does not power back on, and the keyboard lock keys do not respond. The only way to get my system back is to hard reset.
Now I have read several users having similar issues. Many users have solved this in different ways (from display to usb to power to memory), and it's very hard to identify the culprit in my situation.
Other issues (possibly related)
-Sometimes system turns off by itself (rarely occurs)
-Sometimes after desktop is idle for 1 minute, system Logs Off (and in turn displays turn off)
What I've tried that has NOT worked (aside from latest drivers)
-Disabling Hibernate
-Removing all USB devices
-Disabling Wireless adapters
-Disabling Bluetooth
-Uninstalling Bluetooth (yes I've updated to latest drivers)
-Disabling Fingerprint Reader (yes I've tried the latest drivers)
-Updating to latest BIOS (although I updated last night and I think it was to 2.18 that was just released?)
-Installing Intel HD Drivers versions: 3345/3355/3379
-Installing latest Nvidia Optimus drivers
What I've tried that SEEMS TO SOLVE IT (at least temporarily)
-Switching Single Link DVI Cable -> Dual Link solved it temporarily, but the issue came back.
-Uninstalling Intel HD4600 Drivers (using an old 3316; but this causes high CPU usage and System interrupts)
-Disabling CPU management in Power settings in the BIOS (this to me is not a solution)
-Switching to MiniDisplay Port to HDMI adapter & HDMI Cable; this was my biggest victory last night - I was able to get the displays back 100% of the time (3 tests)
-Switching BACK to my DVI adapter and cable - this has me puzzled. I would rather use DVI, so ruled out using HDMI as a solution. Once I changed the cables, I was able to resume the system again (in my few tries). We'll see how long this lasts..
So I'm still not sure what the issue is. Things I would try, but only if necessary..
-Shorter Dual Link DVI Cable
-Different MiniDisplay to DVI adapter
-Reset PC and OS (factory settings AND fresh install)
-Windows 8 Pro (do not upgrade to 8.1)
-Different Memory
After checking the Event Log, I've had Critical Events (system powered down unexpectly) each time I've had to hard reset. I try to see if any Event occured just prior. I've noticed several Warnings for the following, but have found no pattern tied to the crash
-igfx.dll has stop responding / has recovered
-issue with Finger print reader (I need to reference Event Log for details)
-issue with Bluetooth (I need to reference Event Log for details, but I believe this was when I had it disabled in the Device Manager and it was looking for the driver)
Sometimes there is no event just prior to the crash at all, which leads me to believe these are just OTHER issues I need to deal with.
Any other experiences/thoughts/advice would be most appreciated! I have been so incredibly frustrated recently, coming back from another room finding my displays off and having to hard reset. Sure there are workarounds, but I am in seach of a solution.
And this is only ONE of the issues I've had with this device.

My MacBook Pro sometimes doesn't wake up from sleep mode

Dear users, my MacBook Pro (model 5,1 - 15" Late 2008) is behaving oddly since I upgraded to OSX Lion. Sometimes, after going into sleep mode, it doesn't wake up. When I hit a key (space or enter), I see the login screen, but it's not possible to type my keyword. The only thing active is "the spinning beach ball of death", so I have to manually shut down my Mac and start over. This problem (and also other problems) did not happen in Snow Leopard. The only thing that changed in my Mac is the OS; other programs remain the same. I already tried reseting PRAM and SMC, and fixing disk errors. Thanks for your attention.

try running a hardware test and see if you get an error code: http://docs.info.apple.com/article.html?path=Mac/10.7/en/mh35727.html
