No screensaver and monitor sleep mode

Hello guys,
I have the following problem with my Mac Pro (Early 08) and MacBook Pro 2.33 GHz. Both are Mac OS X 10.5.4.
I have installed the latest Security Update 2008-005. After installation both computers have similar problem with Screensaver and display sleep mode. Both simple don't start. I mean that my laptop and desktop computer don't start screensaver and after some time they don't turn off attached monitor (respectively built-in display).
I also tried to change time of both things (screensaver time and "monitor sleeping mode" time) to different time. I also restarted both computers few times already.
My laptop seems working after these "changes and restarts", but Mac Pro doesn't. Monitor is always on.
Please, do you have any info regarding this? I am quite possitive it was caused by mentioned security update, since before that update, both worked perfectly.
Thank you for any help.

Welcome to Apple Discussions.
Create a new account, name it "test" and see how your monitor and screensaver work in that User acct? (That will tell if your problem is systemwide or limited to your User acct.) This account is just for test, do nothing further with it.
Open System Preferences >> Accounts >> "+" make it an admin account.
If the problem is present in the test account also, then it is systemwide. In this case try repairing this with the 10.5.4 Combo Update . This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before.
Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
If the problem does not appear in the test account try starting in "Safe Mode" (It will take a bit more time to startup because it runs a directory check first).
If that works go to System Preferences >> Accounts >> Login Items and remove them. Boot normally and test. If there are still problems, go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving /Users/Home)/Library/Fonts to your desktop and restarting.
Log out/in or restart, if that sorts it start putting items back one at a time until you find the culprit.
Let us know.

i guess you could put the aiport utility app on your iphone, click on the aiport express there, it will show you how many devices are connected to it and the mac addresses of those devices.

Why is there a clicking sound when I close the cover and enter sleep mode?

why is there a clicking sound when I close the cover and enter sleep mode?

Hi katesvca,
I too have an iPad smart cover, and all that clicking sound is is basically the standard lock sound for iOS. The Smart cover is equipped with magnets inside, and the iPad is also equipped with magnets, and when those magnets are closed together the iPad goes to sleep.
I hope this answers your question.

Monitor sleep mode flashes

I have an HP 6000S running windows 7 and a HP Le2002x monitor. When the cpu is shut down the monitor then goes black and flashes a white box saying "monitor going to sleep" This continues until I manually power off the monitor. I have checked the settings in the control panel and I have the sleep mode set to never.

Hi CTHS
I understand your HP Le2002x monitor goes into message "monitor going to sleep".
To begin, turn it OFF with the power button and unplug it over night to allow a full cool down and reset.
Most likely you've let it sleep rather than turn all the way off most of the time. Circuits left on continuously will deteriorate over time. The one for sleep mode is overworked here. Then you need to restart and also check the PC's hardware BIOS power saving options for the monitor. It can override Windows settings.
Any further issues please let me know.

Sending a bug report on the OS and a sleep mode problem.

I find the bug button in Safari really convenient for sending Apple bug reports. And when other applications crash, you usually get an error dialog with a button to send a bug report. But sometimes problems arise that require reporting, but which don't fall in either of these categories. It would be very handy to have a bug "button" for the OS, or perhaps just a menu selection in the Finder menu bar that invokes a bug report dialog box. I know you can dig around and find the URL for Apple's bug report web page, but I am always forgetting it -- I suppose I could just bookmark it, but then I'd just have to dig around in all the bookmarks to find it. Better would be a utility built-in to the OS for sending bug reports (like Safari's). It could also automatically transfer necessary info about the OS rev and such.
The problem I had was this. I have a script that puts my iMac to sleep. I put the script alias on the task bar and a single click puts the computer to sleep (easier than using the menu). Unfortunately, I sometimes click it by mistake when I am trying to click an adjacent icon in the task bar, and the Mac starts going through its cycle to enter sleep mode and is impervious to anything I do to try and cancel it. I tried pressing the space bar continuously to prevent it from going to sleep, but that did not work. Worse, when it went to sleep and I woke it up again, the task bar would not appear, clicking on app windows did not activate them, Finder menus could not be selected, etc. The cursor would move, but I could not do anything else. (I wish now I had noted if the clock in the menu bar was still advancing, but I didn't think to do that.) I powered down the iMac from the power key and rebooted. Things are working fine now.
I wanted to send a bug report on this, but realized that unlike Safari, there was no button or menu selection for doing that. So here I am.
Any suggestions are welcome.
TIA,
Drake

Monitor sleep mode

My HP monitor goes to sleep and won't wake up!! So I have to manually cut the computer off, wait a while then cut it back on. Then sometime the system will just resume but is very slow and other times it will boot up as usual. Help!!

Hello @oldmilva,
I understand that your monitor is having issues with going to sleep and not waking up and not booting up correctly. I am providing you with some steps you can try below:
Step 1. Unplug the power cord from the back of the monitor and the wall
Step 2. Hold the power button down for at least one minute
Step 3. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)
Step 4. Press the Menu button on the monitor
Step 5. Navigate to the Factory Reset option and select it
If the above steps did not resolve your issue you can try the monitor on a computer or other device to see if the issue persists. If it does I think it would be best if you contact HP Technical Support for repair options.
Thank you for posting on the HP Forums. Have a great day!

IPhone 6 bug with texts and lock/sleep mode? HELP!

My phone does not properly search texts. I try to find senders and it does not pull up or not all of them do (referring to individual and group messages). I have to scroll to find the senders I'm looking for. Also, my phone has a delayed reaction when coming out of sleep/lock mode. When I touch my phone to enter my passcode. Is anyone experiencing the same? How do I fix it? Is there some kind of warranty with the software through Apple or my carrier which is Verizon?
Thanks all!

Hi
Follow the following link to put the phone into DFU:
The screen goes blank (DFU) as apposed to the USB screen which is recovery mode which wont allow the software to be downgraded.

Usb music peripherals and mac sleep mode

I have a novation impulse keyboard and a scarlett 2i2 connected directly to my iMac via usb. They seems to stay awake even when the Mac's asleep. Is this usual and, if so, do I have to disconnect them before putting Mac to sleep? If so, do I do this simply by pulling out the usb connectors because there are no desktop icons to eject?

Monitor won't wake up after sleep mode

Does anyone know how to fix the monitor, so it starts up after sleep mode? When my computer comes out of sleep mode the monitor doesn't always come on. Does anyone else have this problem and do you know the cause? The computer is only a few months old and hadn't had any problems.
Thanks,
Shaneil

Well my solution may not be the most cientific one but it works for me (at least until the real solution comes to the public)...
My computer has the problem that when it goes to sleep mode she never comes back... but it the screen that does not comes back... all the system is workin in behind (its like the brightness level was set on the less power possible) so i had to turn off the computer and had to do for a long time some times i had to wait that the computer cooled off a little and then try again to turn it on... I some tried things that the support page of apple said it could be... but did worked out... i dont know i think is a problem over 2 factors...
1. heating (the screen generates to many heat but, TO MANY!)
2. tiger os the OS "sleep mode" (it knows that the screen its heating a lot and tries to go to sleep to prevent over heating and damage)
So based on this i tried conecting a external monitor to the computer while she was unable to "awake" (or to show some thing in the screen)... and it worked whit no problem at all... so my conclusion was to prevent the over heating (1st factor) and the sleep mode (2nd factor)... so I deactivated the sleep mode setting up the computer to a never sleep mode... and to prevente the over heating well I use a low bright and when i need more brightness (to se the colors of what im doing or some thing like that) I use high brightness... when I away I set the brightness level to no brightness so there is no over heat and no sleep mode (cus if it is deactivated and it over heats it will go to sleep anyway...
Soooooo....
1. deactivate Sleep mode...
2. Activate a Screen saver...
3. And remember to contro your brightness your self... and turn it off when you are not using your computer...
well i hope it works for some body :P cya...

Thinkpad X240's and Sleep mode/Hibernate

Hi,
We're having a problem across 4 Lenovo X240 laptops we're using (3 X 20AL-008EUK's and 1 X 20AL-0081UK) that have been bought at different times (1 in January and 3 in February)
All are having issues with sleep mode and hibernation. From various tests it seems that all were able to enter and exit sleep mode without issue once, with the red light on the lid pulsing to indicate it was in sleep mode, however when trying for a second time without a reboot the unit would appear to enter sleep mode however the red light on the lid would remain constantly on and opening the lid would just result in a plain black screen with no cursor or image whatsoever.
On a couple of units I noticed that pressing on any keys on the keyboard would emit the windows error sound, and using ctrl alt del and entering the users password would seem to login suggesting that the graphics driver had failed.
I've tried updating the drivers for the graphics adaptors and the BIOS to the latest available from the Lenovo support website as of today (27/02/14) however if anything this has made the issue worse with Windows crashing from a clean boot to a plain black screen with a mouse cursor (unable to invoke the ctrl alt del menu etc.) 3 out of 10 times across all units
Is this an known issue and are there any work arounds available? Obviously besides just not using sleep mode as we've currently rolled the solid state models out to some of management and the HDD one to a road based sales guy and all like to make use of the instant resume features.
Solved!
Go to Solution.

Hello,
A client of mine brought me Lenovo X240 that wouldn't resume from sleep if you tried to resume it something like 20 minutes or more after it been put to sleep (If you resumed it after a minute or 2 it DID resume).
Lenovo replaced the X240 motherboard because of the client complains, But he said that it just increased the number of times it didnt resumed from one in 7 times to one in 2-3 times.
He also complined that when he connects headphones they doesn't work, But that was solved by updating the audio driver to a newer one.
I started reading lot of posts regarding the resume problem. Lenovo support suggested to him to do a factory restore, But he had activated accounting software on his computer and I tried not to use the factory reset option.
I tried all of the suggestions given with this issue, Here are some :
1. Updating bios
2. updating all drivers (From Lenovo site and then from Driverpack 14.4 dvd)
3. removing fingerprint software and disabling it in the bios and device manager
4. removing relevant drivers (power management, card reader and other related) and reinstalling after restart
5. playing with power management settings of network card
None of these worked, So I decided to keep a try for the system restore
After system restore and instalation of latest drivers (From lenovo and the Driverpack), It still DID NOT resumed from sleep after 20 minutes of sleep or so.I decided to install an image of windows 7 ultimate 32 bit for the test.After installing all the drivers it STILL wasn't solved !!!! Grrrrrr
I gave up......For few hours (Mostly because I needed to get some sleep for next day fights LOL)
Next I resumed the backup of the system I made in case I needed it, And since I saw a poster that mentioned he removed NVIDIA and Intel graphics drivers as one of the proceeses that helped him solved the problem, I tried to fiddle with it.
BUTTOM LINE After updating display drivers from intel site to 10.18, The sleep problem was resolved but then a new problem appeared - Wifi being disabled after resume from 20 minute sleep......Fiddled with it more and rolled back to earliest 17.0.0.34 drivers and now it seems to work fine.
Maybe this solution will help you. GOOD LUCK !!!

Computer freezes when pressure is applied and also won't exit sleep mode

I have a macbook pro mid 2010 with an i7 at 2.66 GHz, 8 Gb of RAM, a 500 Gb seagate hybrid drive and is running on 10.8.5 (Mountain Lion). The RAM and harddrive were installed by me a couple years ago and I generally haven't had any issues with them (I did try to install 10.8.6 but ended up reverting back to 10.8.5 via time machine). When I put pressue on the bottom of the base my computer instantly freezes, the display will do some funky nonsense stuff (not every time) and sometimes followed by 3 beeps (also does not happen every time). I know the 3 beeps often indicates a RAM issue, so I installed the software "memtest" and all my RAM passed. Also, when my computer goes to sleep by shutting the lid of the laptop, it frequently won't come out of sleep and the sleep mode light is stuck on. When it's stuck in sleep mode, the fans turn on and the battery starts running pretty hot. I've tried resetting the PRAM, NVRAM and SMC via this tutorial: http://www.maclife.com/article/howtos/how_fix_mac_won%E2%80%99t_wake . I'm unsure of what steps to take next, and if the problem is a software issue, logic board or RAM issue.

That doesn't appear to be a US model, and this is the forums for Toshiba USA. You may want to contact Toshiba in your region.

HP Pavillion won't go into sleep mode

I have an HP Pavlillion that's about 3 years old. Recently when the comeputer goes into sleep mode (or when I put it in sleep mode), but the computer keeps going in and out sleep mode. It's like the computer goes into sleep mode then about 10 min. later it sounds like the computer is waking up by itself (however the monitor doesn't wake up). The monitor and computer will wake up if I move the mouse or whatever. But now I'm just shutting down the computer completely each night. Any ideas why this may be happening and is there a way to fix it?

Hello Banna1981,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that you think your computer is going in and out of sleep mode yet the monitor stays in sleep mode and both the monitor and computer wake when you use the mouse or the keyboard. I suspect that what you are thinking is the computer waking up is actually scheduled activity or background processes running. If the monitor is staying in sleep mode I do not think that your computer is waking up or if it is it's to process specific activities like checking for updates or checking email etc . . .
If you are concerned I would be happy to assist you, but first I would encourage you to post which operating system you are using. And whether your operating system is 32-bit or 64-bit as with this I can provide you with accurate information on booting in Safe Mode and finding out for sure what is causing this activity.
Which Windows operating system am I running?
Is the Windows Version on My Computer 32-bit or 64-bit?
Please re-post with the requested information and I would be happy to provide you with assistance. Thank you for posting on the HP Forums. Have a great day!

Nokia won't wake up after sleep mode! ( Work aroun...

WCH1.... Posted this in my first thread
Found this somewhere, and it worked for me.
Freezing in sleep mode:
Go to the device manager (you can go to control panel and click on SYSTEM and then device manager will be in the upper left corner). Go to the very bottom and find Universal Serial Bus controllers.
Click on the arrow next to it and it will reveal 2 "USB Root Hub" devices. Double click (or double tap).
On each one, choose Power Management tab from the top. Uncheck "Allow the computer to turn off this device to save power". Then click on OK.
Be sure to do this on both device ISB Root Hub listings. ( The Credit is not mine) but much needed because they keep posting in my first thread !

N80 v4.0707.0.7 Sleep Mode Problem

Hi every body,
Menu\Tools\Settings\Phone\Display\Sleep Mode
Originally It's ON.
It Should go in Sleep Mode 20min after ScreenSaver, but why it don't work true.
Sleep Mode Start, Quickly after ScreenSaver!
Why ?

Hi, I have the same firmware version and my phone behaves the same - screen saver kicks in a few seconds after I lock the keypad, and then sleep mode kicks in right away.
I also noticed something else which I wonder if anyone else has noticed: the phone has entered sleep mode, so the screen is blank and the blue light is flashing. Then I receive a call, and answer it by either sliding the phone up or pressing the answer button. After I end the call, I notice that the blue light is still flashing, and it continues to flash as I use the phone to do other things, when the phone is obviously not in the sleep mode. The blue light will only stop flashing after the phone has entered sleep mode again and is "awakened" by me sliding it open or unlocking the keypad, i.e. not by answering a call.
Has anyone noticed this happening to their phone? If I understand correctly, the only function of the blue light is to indicate that the phone is "sleeping" so I think this is a bug. Thanks for your input.

No screensaver and monitor sleep mode
