When I place my Windows 7 SP1 Pro machine into sleep mode or if it goes into sleep mode after 30 minutes of inactivity then it causes the machine to shut down. No Blue Screen, No Error, just shuts down. When you start up you get the screen that says, Windows was shut down improperly how would you like to start windows. etc. This started happening recently as my computer would go to sleep normally and I was able to wake it up, now it is impossible. My BIOS is up to date and my power management settings doesn't allow hibernating. Any suggestions or fixes so that I'm able to put my machine to sleep again? Thank you!

Using Windows 7 Ultimate SP1 (can't install SP2 - installation fails. Every.time.I.try) and I have the same problem. Replaced the fan because it was bad - thought this was part of the problem. Still happening. If I leave laptop running, it runs normally until I resume use. If I hibernate, it hibernates properly. If I put it to sleep, it shuts down improperly. No help, but thought I'd echo that I am having the same problem.

Hi, According to your description, this issue did not occur before; I suggest you try system restore to get back to a previous time point to check if this issue persists. Meanwhile, you could update the latest chipset driver for test. In addition, you could try to install the following hotfix to check how it works: Sleep and hibernation do not work or a crash memory dump file is not created after you install Service Pack 1 for Windows 7 or Windows Server 2008 R2 You cannot make a computer that is running Windows 7 shut down or sleep Hope it helps.
