Unique Vista Sleep Issue

I had this issue on Vista x64, and attributed it to a corruption during uninstalls/reinstalls/tweaks that I had done. I did a little troubleshooting and came up with this: http://support.microsoft.com/kb/927821/en-us The description is exactly what happens. The screen will fade to black, as if the computer is about to sleep, then the machine will not sleep, and as soon as you move the mouse the screen comes back on.

However, the resolutions did not correct the issue.

I performed a completely fresh Vista x86 install with a retail disc. The computer went to sleep just fine.

Here is the interesting part...after changing the power plan to "High Performance", the computer no longer sleeps. As soon as I change it back, it will sleep again. I changed it according to a recommendation that it will improve gaming performance (I have a desktop, so no battery issue), as the cpu does not have to throttle as much. Things work fine on "Balanced" but the sleep issue when on "Hight Performance" is bugging me.

I cannot find any documentation on this issue, and I can find no difference in the power plan settings that would create this phenomenon. I have not done any tweaking that would cause this. Does anyone have any ideas?

Here is the setup:

Vista 32-bit
2gb 800mhz DDR II RAM
2x WD1600YS HD in RAID-0
C2D 1.86ghz
ATI Radeon x1950 Pro **with latest Catalyst driver**
Intel DG965WH motherboard **with latest BIOS**

 

Nobody has any ideas? I've checked the "wake-on" settings for USB hubs, and disabling them will only prevent the monitor from turning back on. The computer will still not sleep on "High Performance". My current solution is to keep it on "Balanced" but it's hard to believe nobody else has had this issue.

 

Do you have intel turbo memory installed? This totally knackered my pc going to sleep in High Performance mode. I found that the drivers needed a lot of rebooting to adjust to the turbo memory module before it all started playing ball again.

 

I am running a desktop...and do not have Turbo Memory installed. When I was running x64, I installed the latest chipset driver for my board, but it did not make a difference.

So you got your machine to sleep on High Performance mode after updating a driver? Which driver, specifically, did you update (or was it several)? I am fairly certain mine are up to date, but there may be a few that are not.

 

Sorry, my drivers were the Intel Turbo Memory ones. Call me stupid but I thought that as this is "http://forum. notebookreview.com/" tha you were talking about a laptop.

 

You said you checked 'USB Hub' in Device Manager, but did you change the setting on your mouse? Even if it's a USB mouse, you still have to change it under the mouse setting.

 

Don't knock me for looking for advise on a HIGHLY trafficked, and very helpful forum. I can't help it that I like it here.

Plus, I mentioned that it was a desktop right off. Since it is a Windows software issue, I figured this is the place it belongs. I thought if it had happened to someone else, I'd get a response here.

That is a good idea. The strange thing is that it does not affect the "Balanced" power plan. I will look into updated drivers. The likelihood is that this is a symptom of running a KVM switch. I'll try updating some drivers.

 

Is your motherboard "Vista ready"? I have a D865PERL motherboard, and Intel advertises it as Vista ready, but in reality they don't offer much in the way of Vista drivers. In fact, the onboard sound drivers that ship with Vista cause problems, so I had to use another provider's drivers.

If your motherboard doesn't provide the same number of Vista drivers as they do XP drivers, then it might be an issue that you will have to live with. If you haven't already done so, try googling for the motherboard model + sleep. You might find others with the same or similar problems.

 

Sorry I wasn't mocking you more just pointing out that my particular fix would be of no use to you. . Had I known that you have a desktop I wouldn't of bothered telling you what fixed mine, just that you aren't alone wil sleep problems.
EDIT: By the way SP1 is supposed to fix some of these misterious non sleep issues.
