Windows Vista - Sleep issues.

Priapus · 16 Jul 2007 at 14:31

Afternoon Guys.

I've been running Windows Visya Ultimate since the start of the year and it's been fine except for games and a few minor things. However, I cannot get Vista to sleep. If I set it to sleep, my screen goes off, power and HDD lights go out, however my CPU and GFX fans stay on!

. The I press any key and it wakes up again.

If I set it to hibernate, the system just restarts it self. Any ideas why it's doing this, and more importantly how to fix the issue?

Many thanks all!

Have you checked your Bios settings?

Priapus · 16 Jul 2007 at 14:40

Yes, I have. I have tried two power options, S1 and S3; not 100% what both do though.

Vista sleep issues....ahhhh....where do I start?

Are you overclocking?

I had sleep issues in Vista but they related to when I tried to get Vista back out of sleep. It would hang on resume requiring a reboot. This I narrowed down by trial and error to the fact that I was running my memory (Corsair XMS2 PC6400) above stock speed. For some reason, when the timings where anything better than the standard Gigabyte 5-5-5-18 on my P35C-DS3R, I could not run above 800 MHz. When I changed the timings to 4-4-4-12 it was still ok at 800 MHz but would not wake from sleep at 900 MHz. All other normal operation was fine. It passed memtest, stable 24/7 etc etc. Gigabyte just suggested I restore optimal settings in BIOS and start again, which I'm yet to try but I seriously doubt that this will fix the problem since no BIOS setting is causing any strange operation...but it's something I'm certainly going to try.

I have also heard about the 5V rail on some PSUs being insufficient to deal with the load required to bring certain components in and out of sleep.

Regarding S1 and S3 as I'm sure google will tell you, S3 suspends to memory and S1 suspends to HDD...I think that's the way round it goes anyway.

Anyway, please tell us your PSU for starters as well as motherboard and BIOS version (whether it's the latest or not). Also, in Vista's power management, there are many settings that can be changed. I think the three profile are performance, normal, or saver or something similar, but within each there are many settings that can be tweaked and in some cases need to be in order to get Vista's sleep and hibernate to function properly.

Other issues known to cause this are graphics drivers so please also tell us your graphics card.

When I get home tonight I'll tell you my power saver settings as my Vista sleep now works perfectly (Ultimate x64) as long as my memory is 4-4-4-12 @ 800 MHz.

I had nothing but problems getting vista to wake up from sleep, until my PSU blew and I got a new CPU/RAM and motherboard at the same time. Works flawlessly now. Not using a Hiper PSU are you?

Priapus · 16 Jul 2007 at 18:25

Thanks for the replies guys.

Okay, well for starters I am not overclocking at all - Actualy, yes, I am, memory speed is a few mhz above stock; doubt it's that causing it?

Secondly, my stsrem specs are:

Shuttle XPC SN85 G4
AMD A64 3400+ 2.4Ghz
2 x 1GB DDR 400 Memory.
2 x 160GB SATA HDD's
GeGube X1950Pro 256mb

I think I have had Vista sleep correctly before once, not too sure. Also, bios version is the latest the board can have I think, checking on the Shuttle web site.

What should the power option be under the control panle?

Many thanks all!

sounds just like what sleep is supposed to do, what were you expecting?

Sleep in vista, at least for me, sticks everything in RAM and powers the machine off, leaving a small amount of power to keep the ram alive. To look at the machine you'd think it was off or hibernating. I would imagine he's epecting that. Hybrid Sleep I think it's called.

What, with the CPU and GFX fans still running full pelt?? What part of a normal sleep does that sound like to you?

Did you read my post? That's exactly what caused my machine to fail to awake from sleep so I would at least rule it out as a possible cause by dropping it back to stock. Also, you still didn't say what PSU you are using despite me asking the question. I really hate it when you go to the trouble to help someone out and they can't even be bothered to read your post properly. Looking at the specs of your case on google it seems that you have a 240W power supply, which is pathetic. This could be an issue.

Correct, and the PSU issue you had is a common cause of these problems due to the 5v rail voltage required to wake these components.

Not sure what it should be, but I can tell you what mine is and mine is working fine. It's just set to the default high performance settings with display switch off after 20 minutes and sleep never.

I suggest flashing your BIOS (and you haven't damn well answered that question either) and seeing if it makes any difference.

Yes, I did read your post correctly, so sorry I didn't respond in the correct manner. I will try that now.

Well I assumed that from my specs you'd see I can only have one type of PSU. Again, sorry.

It's not an issue of waking the machine up. It wakes up just fine. Also, if you knew Shuttle PSU's, you'd know they are very good PSUs and can't judge them by their voltage rating.

Again, I assumed that since I said I did try changing BIOS settings you would know I have done that. But, I will set it back to stock now. Sorry.

Well I resetted the CMOS I changed power settings with in windows and in the BIOS.

Still no go.
