Hi KeithVenable,

Check boxes may be disabled and greyed out probably due to third party drivers that want to show manufacturer’s icon instead.

You can go to the link mentioned below and run “Fix it”.

http://support.microsoft.com/kb/945011

After the process is complete, please restart your computer and enable the power option in notification area.

You can refer the following link for more information:

Hope this helps.

Regard,

    I'm running Windows 7 64bit Home Premium

    I performed all these steps (that BTW are detailed in a Microsoft KB article) and it helped clean up old junk but didn't restore the Power icon. I also run the Microsoft Fix-it program.

    I found the problem was a driver from an APC UPS. I went to batteries in device manager and uninstalled the entry for the third party device. I took the precaution of first finding out what the .inf file was (you can find this in the details section of the device properties under inf name). Again being carefull I didn't check the delete driver file from the uninstall pop-up, I just renamed the inf file(s) in the Windows\inf directory. This did the trick after restart!. The power icon showed up again and now Windows was effectivelly managing the power as in the batteries section of the device manager the APC device was replaced by a HID UPS entry which uses the Windows battery.inf file.

    Hi Job,

    This is a new computer build.  The power icon never appeared and was always grayed out.

    Gigabyte Z68

    Intel 2500K

    Windows 7 professional 64

    Administrator account.

    I followed Method 1 and there were no files which needed to be replaced.

    I followed Method 2 and the power icon and action center icons were grayed out.

    When I booted up this morning (prior to running the Methods above) my action center icon was not grayed out.

    After I followed the Methods and returned to my account, the action center icon was also grayed out. 

    Thanks for your help.

    Chris

    Hi Chris,

    Have you made any changes to your computer recently?

    I would suggest you to follow the steps and check if it helps.

    Method 1: Run System File Check (SFC) scans and checks if it helps.

    **How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7**

    Note: System File Checker gives an administrator the ability to scan all protected files to verify their versions. If System File Checker discovers that a protected file has been overwritten, it retrieves the correct version of the file from the cache folder (%Systemroot%\System32\Dllcache) or the Windows installation source files, and then replaces the incorrect file. System File Checker also checks and repopulates the cache folder. You must be logged on as an administrator or as a member of the Administrators group to run System File Checker. If the cache folder becomes damaged or unusable, you can use the sfc /scannow, the sfc /scanonce, or the sfc /scanboot commands to repair its contents.

    Method 2:

    Step 1: Create a new user and then check if it helps.

    **Create a user account**

    Step 2:

    If it works fine in new account, then your current account might be corrupted.

    To fix a corrupt account, please follow the steps in the link and then check if it helps.

    **Fix a corrupted user profile**
