"Allow this device to wake the computer" option resets

Hello All,
I'm wondering if anyone has come across this.  Everytime I disable the Power Management option "Allow this device to wake the computer" click OK, the setting stays, once I reboot the computer, the option is enabled again.
I've checked the BIOS there's no setting for this, other than WOL - which is disabled anyway.
Drivers has been updated
Windows patches are up to date.
Checked the registry to find any option, but I couldn't find any reference of PnPCapabilities
In case you're wondering, the reason I'm trying keep this option turned off is because a lot of my users' laptops turn on in the middle of the night to do windows updates when it is checked on.  When I check it off, they're fine.

Hello Jacky ,
Do you mean that after rebooting the computer , the option ‘Allow the computer to turn off this device to save power’ is enabled?
And you are the only one user that affected?
If you are the only user that affected, please refer to the following article to fix the corrupted profile.

If you are not the only user that affected, please go to the manufacturer website and update the driver.

  • 'Allow Bluetooth devices to wake this computer' always dimmed

    I'm trying to use an external display with my 1.33ghz 12" G4 PB and use a BT mouse/keyboard.
    I've been through this technote http://docs.info.apple.com/article.html?artnum=300562 on "How to use your PowerBook G4 or MacBook Pro with the display closed and a Bluetooth keyboard or mouse" and this http://docs.info.apple.com/article.html?artnum=86524 "What to do if "Allow Bluetooth devices to wake this computer" option is not available"
    I've updated my BT software, updated firmware but still 'Allow Bluetooth devices to wake this computer' remains greyed out! Meaning everytime I close the lid on my PB when an external display is connected my computer goes to sleep.
    Please, anyone able to help?

    You have not applied the Apple Bluetooth Firmware Updater. To use this option several steps are required in the following order:
    Download the Apple Bluetooth Firmware Updater
    Install it
    Launch it from Applications > Utilities > Bluetooth Updater
    Apply it to your adapter (takes very long).
    In most cases step 3 is missed. You have to start the already installed updater yourself (do not ask me why).
    Additionally you might have broken your Apple Bluetooth Software. Apply the Mac OS X v10.4.5 combined updater which contains the latest version.

  • Choose only One bluetooth device to wake the mac.

    Hello, recently I have been having a unacceptable bt keyboard problem. This keyboard (3x AA model) with updated firmware, disconnects itself from my mac when my mac is sleeping and wakes it up with a "connection lost" It normally starts to happen when the batteries are at 71%. Basically I want to disable my keyboard from waking my mac BUT I do want to wake my mac with my good ol magic mouse. Their's only 1 option and that's to disable all bluetooth from waking my mac? c'mon apple that's no option at all.  I want to choose only my mouse to wake up the machine. Please help me out you guys, It will be much appreciated and It will help the environment if I quit throwing out my batteries with 70% charge left. Was not this new firmware (1.1) suppose to conserve battery power. I am mind boggled please help. Thank you all.

    Hello:
    To my knowledge, it is all or nothing.  There is no way that I am aware of that you can selectively have a device wake the computer.

  • "Allow power button to put the computer to sleep" setting is not available but button does it anyway

    This has never happened before. Computer stayed at gray screen with no progress wheel so I held the power button to shut it down. Since startup afterwards the power button sleeps the computer. There's no "allow power button to put the computer to sleep" choice available in Energy Saver but button does it anyway. Is there a defaults command that will fix it? Something else?

    I've had Mavericks for a week and a half. I don't believe yesterday could have been the first time I used the power button in an attempt to get the Restart Sleep Cancel Shut Down box, but I've been around long enough to know that memory will fool you.
    Yours 'til it doesn't,

  • Since upgrading to LionEvery time I wake the computer from sleep mode I have to wait several minutes until the computer connects to the Internet

    Since upgrading to LionEvery time I wake the computer from sleep mode I have to wait several minutes until the computer connects to the Internet

    I have found that Lion is slower to connect to WiFi when awakening than were previous Mac OS X versions.  However, the WiFi connection usually takes less than 15 seconds unless a Time Machine backup was interrupted when my computer was put to sleep.  When this happens and the computer awakens, the Time Machine backup attempts to continue prior to the WiFi connection having been made.  Until the Time Machine backup fails due to its inability to connect to my Time Capsule because of no WiFi connection, or I stop it manually, the WiFi connection will not occur.  So if Time Machine backups are on, you may be experiencing this bug which I have reported to Apple.

  • HT4718 re magic mouse,it seems that when i put my mac air to sleep with my magic mouse left on and wake my computer with the mouse the wi-fi does not connect. but if I put the mac to sleep and then turn off the mouse and wake the computer wifi connects wh

    ... does my iMac model... support Hibernatemode 3 alias "Safe Sleep" to protect my Mac against damages due to power outage?
    You can set hibernate mode to 3, but it seems to me its only benefit could be if power were to be lost after the iMac was already sleeping. Sleepimage is written to disk prior to system sleep. If your iMac lost power while it was "awake" you would certainly lose any unsaved work no matter what hibernate mode you choose.
    The problem is that an iMac without power no longer sleeps, it's dead. Upon restoring power you need to cold boot, and I seriously doubt sleepimage can be forced to load in that event. Sleepimage is loaded upon wake from "safe sleep", not from boot as far as I know.
    It is simple enough for you to try, so go ahead and see if it does what you want. Other than creating a 16 GB sleepimage file it did not appear to do anything beneficial on the iMac I am using though (a later model).
    The file location is /private/var/vm/sleepimage
    Configure hibernatemode, verify the file is created, do some work on your Mac, don't save it to disk (and don't use Pages or similar app that saves work on its own), let it sleep, then pull the plug. I think you will see what I mean.

  • Preview takes forever to open, much slower than on my old MacBook. It has been like this since I bought the computer last January. Why is Lion so much slower?

    Preview takes forever to open, much slower than on my old MacBook running Snow Leopard. It has been like this since I bought the computer last January. Any ideas?

    Take it to an Apple Store for testing. If you don't get immediate satisfaction, exchange it for another one, which you can do at no cost, no questions asked, within 14 days of delivery.

  • 'a device attached to the computer is not functioning'

    I ran into an error today importing files from my iPhone5 to my PC. The error read:
    'a device attached to the computer is not functioning'
    It happened repeatedly for certian (larger) files that I would attempt to transfer.
    The solution, I found was to ensure that I was using an authorized iPhone lightning cable. The cable I used first was a $7 knockoff. It works great for charging, but data transfer is sketchy.
    Plugging into an Apple-made cable made the problem disappear!

    There were stories published that indicated some companies built and sold lightning cables before Apple had finalized the specifications for them. The cable you purchased might have been one like that. Apple certifies cables the meet the needed specifications and that info appears on the packaging.

    Your friend will have to create his iCloud account on a different iOS device.  His device has already created the maximum number of iCloud accounts and cannot create another one.

  • Why did the Apple TV update remove "home movies" from the computer option in Apple tv?

    AApple TV auto updated.  22 sept 2014.  Most of the movies I have on my iMac were under itunes as "home movies".  The Apple TV update removed the ability to see home movies in the "computer" option in Apple tv.   I can see them on my iMac, but no longer have access thru my Apple tv.  I can still see the few that are physically in "movies" in iTunes, but the Apple TV will now only show them.  Thanks

    Hello bernsteinr,
    It sounds like an issue with Home Sharing. Check out the article below for more information on getting Home Sharing working again so you can see all the movies that you have on your iMac show up on your Apple TV.

  • HT4946 How do I get what is on my devices back onto the computer?

    My Ipod, Ipad 2 each are working fine but my computer died and new OS installed, the computer is now blank, I downloaded Itunes onto the computer. How do I get what is on my devices back onto the computer?
    Thanks,
    Craig

    Sync is only oneway, from PC to your device. Unless you have the music on your PC, iTunes is going to wipe out what you have on your device if you are syncing to a new library.
    You can only transfer Purchased music over to Itunes on your PC.
    iTunes Store: Transferring purchases from your iOS device or iPod to a computer

    As for you own music, you may have to use a third party software. A good Free one is called Sharepod which you can download from Download.com here:

    Take note that sharepod does not support iPad at the moment.

  • Lightroom opens fine initially, but when trying to open a different catalog it will go through the process but never reopen again. I can't get it to open at all until the computer is reset.

    Lightroom opens fine initially, but when trying to open a different catalog it will go through the process but never reopen again. I can't get it to open at all until the computer is reset. I have been using Lightroom 4 for 18  months now and this problem just started happening in the last month.

    No error messages. It acts totally normal but just never reopens when I try to reopen a new catalog. I create a catalog for each of my clients....I have done this since I started using lightroom as it seems tidy to me. But, I have never had this problem until now. I am using a pc and vista and Lightroom 4. Thanks.
