My Computer Won't Stay Shut Down!

Hi,

I have a brand new Dell desktop (got it Friday) with Vista Home Premium 32-bit SP1 on it. The problem I'm having is that I'm not able to shut the computer off.

I'm going to the start menu, using the right arrow to display the full list of options (sleep, change users, restart, etc) and selecting Shut Down. Vista goes through the normal routine (shutting down, please wait, etc). After a couple of seconds the fans and hard drives shut down in the CPU and my monitor goes into sleep mode because it's not getting a signal. HOWEVER, in another second or two, the fans and hard drives spin back up, just like I'd pressed the power button on the CPU and the PC boots back up!

It was happening before I applied SP1, so that should not be the problem. I can't say for sure that it has been happening from the very beginning, but I think it has been. The first few times it happened I thought that maybe I had put it in sleep mode by accident (I typically hit shut down and leave the room before it's done). I haven't had time to reinstall any of my software yet, so it is pretty much as delivered from Dell.

Has anyone else experienced this problem? And more importantly, does anyone have any suggestions on fixing it? Right now the only way I can shut off my PC is to catch it on the reboot and hold in the power button on the CPU until it powers off.

Thanks for your help!

Disable Wake on LAN (WOL) in BIOS. Make sure the power management setting are also disabled.

Would you first try the remote shutdown command to check if reboot comes from vista or bios.

Start/Run and type in: shutdown /s

Does the computer reboot?

Hi JSW (Frustrated), My PC won't stay shut down!

See if this tutorial can help you. I would be sure to also check your "Wake on ..." options to disable them in BIOS and for the Network (LAN) device.

Hope this helps,

This one turned out to be a BIOS setting. The Wake on LAN option was disabled, but in Power Management the 'Remote Wake Up' and 'Auto Power On' options were both enabled. I disabled them and the PC shuts down normally now.

Thanks to everyone for their help!

Your welcome JSW. I'm glad to hear that it is wroking properly now. Thank you for the feedback.
