I'm using Windows 7 64bit on a Vostro 430 desktop computer. With my laptop, there is a power notification icon the system tray I can click to change power plan. On this desktop, the notification icon does not appear, and the option to turn it on is greyed out.
Is there any way to turn this option on? I change power plans regularly depending on what I'm doing. Downloading large files for instance requires the computer to not sleep, whilst watching movies, I generally like the brightness turned up.
On Microsoft Windows Forums > Windows 7 Forums > Performance and Maintenance a question was asked: power icon from the task bar is missing.
The answer states that Check boxes may be disabled and greyed out probably due to third party drivers that want to show manufacturer's icon instead.
They suggest you go to http://support.microsoft.com/kb/945011 Most Microsoft articles get moved on a daily schedule to prevent anyone finding an answer, but with a little luck you might find it.
Power Options are usually meant only for laptops, where you want to save battery power.
You can find some options in the Control Panel, but most are not available because you don't need them.

Surely a desktop should have all the software options of a laptop, even if they aren't particularly needed? I find that even on my desktop, I am missing Windows Mobility Centre and the ability to quickly change power options.
Anyway, thanks for the answers, I'll guess I'll just have to do it the manual way from now on.
Desktops usually do not have the hardware connections needed to support all the possible power configurations of a laptop. I (and many others) have had mucho problems trying to run even sleep and hibernate smoothly on desktops, This not just with Dell but other brands. Most functions are designed to reduce power drain during battery operation. You still have screen shut off and sleep mode/
I hope I can revive this thread so late after the last post - I am in the same situation.
I use my XPS 8100 Desktop (W7-64) to run audio production software and want to be able to switch to my "Disks On" power profile without having to go into the Control Panel. I used to be able to do this on my old XP machine via the Power icon in the system tray but on this one the option to enable it is greyed out.
I have also discovered that this may have been disabled by the manufacturer and I have read the above discussion. I understand the argument that power-saving options are not as important to desktop users but we also get electricity bills! I want to normally run under the Dell default setting but change to "Disks On" when needed.
Can someone confirm whether this is a Dell setting and describe how to undo it?
Thanks and regards,Swatcher
Swatcher - I'm yet to try this solution, but others on the Microsoft forum have verified it worked for them. It's been a long time since this thread was started so you may have fixed the issue already.
