Monitor Wake Up !

All of a sudden, for no reason at all as nothing has changed in my PC, my monitor has stopped waking-up when I move the mouse. Sometimes I have to revert to re-booting the PC just to get a picture back on the screen.
I have a Samsung 173T which has a flashing green LED when in sleep/standby/of mode.
Moving the mouse and hitting keys often does not bring a picture back to the screen.
Sometimes hitting the Exit/Source key on the monitor will bring the screen back to life but the picture will flash on and off a few times before stabilising.
This has been an intermittent problem for the past 8 months with intervals of about 8 weeks before the problem starts again.
Can anybody please tell me how to resolve it ?
Thankyou.

I think TS meant "reseat" the video card. Turn off your system, turn off the PSU(unplug it even), hit your power button to discharge the capacitors, and pull the video card out of the slot and re-insert the card to ensure it is seated properly in it's slot. Reconnect cables and PSU plug, turn on the PSU, and turn on your computer. Remember to touch the PSU and case to ensure you don't fry a component with a static discharge.

Monitor wake up issues

I am having inconsistent monitor wake up issues. If the CPU is on and past the bios boot and THEN I turn on the monitor all works properly. However, the monitor will NOT come out of power save / hibernation mode. I have tried different monitors with the same behavior and am on my second ATI 9600 Pro 128MB graphic card. I have installed the latest Catalyst drivers (4.0) and flashed the MoBo bios (amibos 3.31a) and still no change in the effect. I am suspect that it is some bios setting but can't figure out what the issues are. As a side note, I have had twice in about 40 boots an error: "Dram timing is too tightly so reload timing". The DRAM timing configuration is enabled by SPD at 3-3-3-8-8 (unchangeable in current mode).
Suggestions greatly appreciated!
SYSTEM:

You can set your DDR timings manually by disabling SPD in BIOS. Before you do that, be aware of the exact description of your memory sticks and try to find out in Kingston Website about possible timing values.
About the problems with the Monitor, in BIOS you should have a menu 'Power Management Features'. If you have
ACPI Standby State choose 'Auto'
Re-Call VGA BIOS at S3 resuming choose 'Disabled'
Power Management/APM choose ' Enabled'
Suspend Time Out 'Disabled'
On this menu if you have a Submenu 'Set Monitor Events', get in, and if you have something like
FDC/LPT/COM Ports choose 'Monitor'
Primary Master IDE 'Monitor'
Primary Slave 'Ignore'

MacBook Air: It's impossible to turn on the monitor (wake up) without reboot ...

It's impossible to turn on the monitor (wake up) without reboot if i click any key in the same point when OS is going to sleep. If 1-2 seconds manage to pass - Everything is ok!
Please fix it!

use the last combination the three finger reflash you will lose all your data but your phone might work, if the last code does not work you ought to contact either provider or nokia care point for assistance
*#7780# - Restore factory settings - resets all the settings to the default ( you will not lose any data)
Make sure you back up your data as you will lose all of it when you perform option 2 or 3 on this list.
*#7370# - Reformat your phone
This you perform as a last resort. Nothing else is working. Turn off your phone, hold the following buttons while pressing the power button. (the default code is 12345)
re-flash - hold the following buttons *, 3 (number button) and talk/green key. turn on the phone and do not release those buttons until you see the Nokia boot up screen.
If these codes are not working the only thing for you to do is contact your Nokia Care Center/Service.

MacbookPro + External Monitor wake up from sleep

Hey,
If I connect my mbp to external monitor and press sleep and then close the lid, 30% of the cases I cannot wake it up. I have all updates in Mountain Lion.
Any thoughts about it? Software bug?

But still, the sleep issue persists, so it is a more subtle timing issue. I upgraded my MBP with a Corsair 8GB kit ( http://www.corsair.com/us/corsair-mac-memory-8gb-ddr3-sodimm-memory-kit-cmsa8gx3 m2a1333c9.html ) and it indicated it had 9-9-9-24 CAS timing. It has worked flawlessly till now. Note that my Mac is a Late 2011, whose memory runs at 1333 MHz.
As far as I can tell, the 13" Mid 2010 models used 1067 MHz memory with 7-7-7-20 CAS timing: http://www.corsair.com/us/corsair-mac-memory-8gb-dual-channel-ddr3-sodimm-memory -kit-cmsa8gx3m2a106c7.html

Wake Up! Wake Up! Monitor, Wake Up!

Like others, I am very pleased with my new MBA 2.13/4gb/256gb. But waking up the external monitor is driving me nuts! I can't find any consistency in what it takes to wake up the monitor from MBA sleep mode once I connect it to the DVI adapter. The monitor is a Samsung 32" that fully supports the resolution, and produces a great looking image - when it works! No problem running both the MBA open with the monitor, but once I close the lid and press the spacebar on the Apple bluetooth keyboard (or mouse for that matter), most of the time the monitor just sits there. About every third time, it works just like I would expect, but the other times, it just refuses to recognize the MBA. I suppose that the MBA just isn't sending a signal to the port, but the inconsistency is what's driving me nuts. I have installed all updates through Software Update, but that didn't resolve the problem.
Anybody found a solution yet?

UPDATE: Even though I did a Software Update immediately following my data migration from the MBP to the new MBA, I went out to the Apple site and downloaded the update again. Presto! Now the external monitor and MBA are functioning well together - just like I expected. Interesting.... Maybe it was the reboot, maybe the original update was overwritten by something else. I dunno.... but whatever the cause, everything is now behaving like I wanted.

Turning on monitor wakes mac from sleep

I've hooked up my G4 Gigabit Ethernet to my HDTV, and I'm happily using it to play music and watch slideshows. Very happy to breath some life back in the girl.
One issue though: If I turn on my monitor to watch TV it wakes the G4 from sleep (the state I keep it in most of the time). Most of the Shareware or Scripts I've seen are for the exact opposite issue -- trying to keep the computer from going to sleep -- I want to keep the computer asleep!

Options is there in Tiger. This is a screenshot of the Display Preferences from a Tiger volume.

Attention: HPIO Trap Monitor wake issues on Leopard

Guys, I've never had any sleep issues with my Intel iMac before; but it seems like the latest 10.5 updates are NOT compatible with the HPIO Trap Monitor, which is part of the software package installed for HP all-in-one printers on Macs...
In 2 or 3 occasions during the last couple of months, I wasn't able to wake my iMac from sleep, having to resort to a hard reboot. It's nothing with 10.5.7, because this ALSO happened with 10.5.6.
After some analysis of console messages, I discovered the following:

My question: my printer works fine so far, but I am afraid this driver or specific process is not compatible anymore with Leopard...what happens if I erase it from my system? Thanks in advance!

Reinstall the latest HP software. I have no such crashes with my Photosmart 4280 AIO attached to my iMac. Version 2.6.0 runs without issues.

Computer won't sleep, my monitor wakes up my computer

I recently purchaced at T232HL for my PC. It was working fine, now whenver my PC blanks the display or goes to sleep the monitor starts looking for another input then wakes the PC back up. The computer is plugged into HDMI1, when it goes to sleep the monitor tries HDMI2, VGA, then back to HDMI 1, then displays "No Signal", the amber light comes on briefly (0.5s) then the screen comes back on to my lockscreen with the PC wide awake. Using powercfg -lastwake I can see that a USB device woke up the computer. I tired unplugging each device 1 by 1 and found that when the USB to the monitor is unplugged it goes to sleep without issue (it still cycles inputs, but doesn't get woken up in the end). What's going on here? I don't think the monitor was cycling through input when I first started using it, and it certainly wasn't staying awake. Any hints on how to prevent auto input searching and preventing the monitor from waking up my PC? Thanks-Ian

RidgePirate,
Go to the device manager.
Right click and go to the properties of your display adapter.
Go the power management tab and see if there is an option to wake the computer from sleep.

Monitor wakes from sleep twice

Hello,
For the last few days I have noticed a couple funny things happening. When the Mac Pro wakes from sleep my HP 2475w monitor, which is also in sleep mode, wakes up, gives me a message that no signal is received, goes back to sleep and then wakes up again. This happens in about 10 seconds or so, but once awake works fine (for the most part).
The other thing I've notices for a slightly longer time, maybe 2-3 weeks, is sometimes when I move my wireless mouse (logitech M305) the monitor goes black for a few seconds but always comes back on.
I wonder if these two occurrences are related and may be due to something wrong with the HD 4870 or the video card? Someone on a previous post said something about cleaning the dust from the video card with canned air.
Does anyone have any suggestions what I might try? I have apple care but before I go down that road I wanted to check here first.
One other thing that I see reported a lot but I've learned to live with, is the problem of the monitor screen occasionally turning to snow while coming back from sleep. It always rights itself with 2-3 seconds.
Thanks, Dennis

*"Anybody have any ideas?"*
Call Apple and arrange for repair.

Monitor wakes unexpectedly

This problem pertains to my wife's mini (1.42 GHz, 1 GB RAM, 10.4.3), not my own machine.
We recently had a problem where she couldn't use printer sharing to print through the printer connected by USB to my machine. Resetting the NVRAM seems to have cleared that up, but has created a new problem.
Normally we do not power-down or sleep our machines: we let the displays shut off after a few idle minutes, though. Since resetting the NVRAM on her machine, her display (a Dell 19" LCD, fwiw) will periodically activate itself. I haven't timed the interval, but it seems to happen roughly every 3 hours. I've checked the Energy Saver pref panel, and it seems to be set the way I want.
I'm comfortable dropping into Terminal and munging around in there--if that's the quickest way to fix it, I'm happy to try.
iMac G5 2.0 GHz Mac OS X (10.4.3)

Here's another one; you never know!
A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--(username is your name or System Administrators name).
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
In some cases, running MacOS X's cron tasks-maintenance that the OS performs automatically if you leave your Mac on 24 hours a day-can resolve many sleep problems. If you don't want to leave your Mac on, you can use MacJanitor, Yasu, or OnyX free at Versiontracker.com.
Cheers!

Since Lion, primary monitor doesn't wake from long sleeps

Since installing Lion, my iMac doesn't wake properly from sleep when it's been off for a while.
I have two monitors and the second one wakes fine, but the main one - the iMac itself - doesn't return unless I reboot.
Any thoughts?
Thanks

Try turning off hibernation mode - run the following in terminal:
pmset -a hibernatemode 0
You'll likely need to do that from an admin account using sudo. The reason why this happens, I think, is that you close the lid and sleep the machine while the system is in the middle of doing something (updating the hibernate sleepimage, locking the screen, etc...). then when you open the lid, the system is still going through the close-down process and the monitor wake call gets lost in the shuffle. turn off hibernate mode to speed things up, only turn it back on when you need it (like when you're in a situation where you'll need to switch batteries without a power cord).

Monitor doesnt wake up when booting first time, have to restart - k9n ultra-2f

So, I have few problems. The main problem is in da topic:
I bought an used computer about two weeks ago. I installed windows and all drivers etc.
With the old bios (cant remember what version) all was okay except always in boot an error message was shown that said something that the proseccor could not be recognised but the processor was still shown right in My Computer.. :s
Because of that error message i decided to update bios. I updated it throught live update 3 to v.3.6 and now i dont get the processor error message but the monitor doesnt wake up in the boot.. I have to press reset button and then when the monitor wakes up there comes an error message what says something like "Warning!!! The previous performance of overclocking is failed, and the system is restored to the defauls settings". Then I press any key and windows boots normally.
I reupdated v.3.6 bios today manually from floppydisk but the problem didnt go anywhere.
I have searched this forum but cant find same kind of problem posted.
Can somebody please help me with this and tell what could be the problem?
Also when booting second time so that the monitor wakes up, i get four alert sounds.. What could those mean?
My computer is pretty powerful (amd athlon 64 5600+ x2, club3d gf 7950gt, 2gb 533mhz..) It should be very smooth and fast but it often appears slowliness and ..how can i say it.. temporary tilting? :p And the 3dmark03 benchmark gives me 19465 points, it should be giving much more. The computer is clean, no viruses or adware. What could cause this?
Sorry for the messy message and bad english and im not really good at computers

Thanks for the reply.
I didnt have this issue before updating BIOS..
And i didnt find jbat1 from my k9n ultra-2f. I didnt even find it from the mb manual. Theres only a Clear CMOS Button: SW2. I pushed it few times and then i rebooted my computer. At the first time the monitor woke up instantly and i was like wohooooo but then i shut down the computer and booted it again.. The monitor didnt wake up before pressing the reset button, the same problem was back.
I think that the SW2 button reset the bios settings like the jbat1 would do, because i had disabled the big logo at the boot and after pressing SW2 the logo was back.
Then i set the memory vcore to 2.0V but it didnt help. Infact i think the computer had come a bit more slowly.. :s I think it may be the RAM what makes my comp so slow... dunno.

Leopard won't wake monitor from sleep on Power Mac G4

I had no problems with my Power Mac dual G4 867 while running Tiger, but immediately after a clean install of Leopard (a fresh install - no third party apps) my Dell 17 inch LCD monitor will not wake from sleep.
The monitor comes on just fine when the computer first boots, but if the computer sleeps, and I wake it by hitting a key on the keyboard, the drives spin up and I can hear that it thinks it's working just fine, but the monitor won't wake.
I know that the computer is working fine despite the sleeping monitor because I can hear VoiceOver working after a clean install of Leopard (if I let it sleep after the Welcome movie) while asking for user information.
I reinstalled Tiger, and the problem disappeared. The monitor wakes reliably from sleep with a fresh, clean install of Tiger. But with Leopard, even turning off and on or unplugging the monitor doesn't wake the screen.
I have reset the PRAM, the PMU, and the Open Firmware (the firmware is up to date). I even opened the case and pulled and re-seated the video card. Nothing seems to work, so I have just set the computer to never sleep. Not a great option, given the insane fan volume in the G4 MDD model.
Thanks for any suggestions anyone can offer.

I'm having similar problems with both a new MacBook Pro and a new Mac Mini, both connected via a Gefen DVI switch to a Dell 2005FPW monitor. Putting the MacBook Pro to sleep while in dual monitor mode will crash the machine. Putting the Mac Mini to sleep won't crash it, but the monitor won't wake—the computer wakes, but the monitor stays black. I can use Screen Sharing to connect to the Mac Mini and restart it (the only fix, as far as I can tell).
I suspect this is a software issue, because my old PPC Mac Mini would usually wake from sleep. The Gefen support people say this shouldn't be happening.
Anyone having this problem should probably post it as a bug at Apple's Feedback page. I think reinstalled, resetting PRAM etc. is probably a waste of time. Meanwhile, don't sleep your monitor.

Late 2012 mac mini display signal drops while booting and monitor goes to sleep

I have a new Late 2012 Mac Mini. I have had it for a week, what just started happening is that during restart, the video signal drops and my monitor goes to sleep. I then have to toggle through the input options on the monitor and the video signal is detected again and the monitor wakes up.
Here is what I see - If i shut down and then power back up, I get the grey screen, then the apple logo, then the little status circle spins for a few cycles then stops and then the screen goes black and the monitor says signal lost and then 5 seconds later goes to sleep.
It is possible it is my monitor but, I haven't had any issues with it and i only drops the signal like that during a reboot.

Welcome to the family. Search this forum for the main thread for this problem titled: "mac mini 2012 video blinking out".

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
