Win7 Home Premium no longer entering sleep mode

Hello,

I've recently started having issues when putting my desktop into sleep mode. Whenever I attempt to put it to sleep, either by the start menu or via an elevated command prompt, the screen goes off as it usually does, but the fans stay spooled up and the screen instantly comes back on about a second or two later, back to where I left off.

There are no requests in the powercfg command, and there are no devices that are armed to wake. I've also made sure that there are no media sharing options keeping it awake.

Any more tips, short of an OS reinstall (something I'd like to avoid), would be appreciated. I can provide any more information if you need it.

Thanks in advance :)

Quick question about you're setup. Are you using an SSD and if so did it come with any software. I know with my Samsung Pro, the software it comes with auto sets some of the power settings to prevent it from being able to go in to sleep mode. Even if I go in to power settings and try and over ride it, it doesn't let me, changes have to be made in the SSD software.

Also whats your system config, it may be as simple as something funky in the bios but no way to know without your specs.

Strange you should say that actually, I'm using a Samsung 840 (not the pro). Here are the full specs:

Asus P8Z77-V motherboard
Intel i5 3570k with stock cooler
Corsair Vengeance 16GB 1600mhz
Gigabyte Radeon HD7950 3GB GPU
1TB Seagate HDD for storage
120GB Samsung 840 SSD
XFX 650W Semi Modular PSU

I believe it did come with software, but I don't recall installing any since I put a fresh OS on it immediately.

Cursory search for your board and sleep issues comes up with you not being the only person with this issue. This obscure reference that may have some bearing.

As for your SSD. The software for the 840 (Samsung Magician) isn't a bad idea. It provides Over Provisioning for maintaining the health of the SSD, allows you to update the firmware and might actually help with your power settings since it apparently overrides anything you put in to the Control Panel Power Settings.

Grabbed the Magician software off the internet, which led to some interesting information about the actual speed of my SSD which I'm looking into now. I fixed it, but I'm not sure what I did. I believe the problem was that the power settings were allowing USB Selective Suspend. Disabling this seems to have fixed it.

Thanks for your help! :)
