Computer won't sleep.

Hi All

I'm still trying to get my computer to sleep. I'm using Vista and Windows XP. When I click on sleep on XP or Vista, machine shuts down, power/hdd light off however case fan stays on and GFX fan stays on!

If I select hibinate, the machine just restarts normally. So I fugure it's to do with BIOS?

There are few options for power managment in there. S1 and S3 and Video off mode. blank screen, DPMS (or something) and another option i can remember.

This PC used to sleep. Now wont.

Shuttle XPC SN85 G4 V2.
AMD A64 3400+ 2.4Ghz
2GB DDR 400
X1950Pro
2 x 160GB SATA drives.
Any ideas guys?
Latest BIOS as well. I think

Thanks!!

Hi

Tried S1 and S3, no difference. PC either restarts or just keeps fans running. When fans are running it is in sleep, just fans on. As I press a button and it comes back on as it should.

Okay, will have a look tonight. I also have video off mode: Blank Screen, DMPS VHS or something no idea what that is, HDD power down and a few otherthings...

Any ideas guys?

It used to work.

Board is made by Shuttle. FN85. The Shuttle is a SN85G4 V2.

So you have it set to S1 & S3, then enable hibinate...I will try tonight, but doubt it will make much difference. It's not a Windows Vista Ultimate issue as it does the same thing in Windows XP Professional.

Tell me, having high end parts in the system, won't cause this as well? :confused:

Well in any case, I can't get either of them to work!

Priapus · 29 Jul 2007 at 16:21

No, I haven't. Should they be enabled? And how many minutes? As it's 1 to 15 minutes for HDD susspend time, I think...

Okay, done some more testing.

Windows XP Professional:

Hibernate: Will Hibernate just fine, fans go off ect.

.
Sleep: Screen goes off, HDD powers down. CPU fan stays on, GFX fan remains on. However PC comes out of sleep like it should do and goes into sleep like it should do. Except the fans running.

Windows Vista Ultimate:

Hibernate: I can't see how to get it into Hibernate now as the option has dissapered.

Sleep: This causes the system to restart then give and error message upond booting up, saying Windows wasn't shut down correctly.

No idea what else to do now though.

Yes, unplugged all USB devices that were not needed.
