Severity: A

When waking up from sleep mode with a dual monitor setup, the computer does not display anything either monitor and has to be manually shut down. The problem does not seem related to motherboard settings such as Wake-On PCI-E, Spread Spectrum, or changing the suspend mode between S1/S3/S1 & S3. The cause of this problem began from a video card upgrade from a BFG 7600GT to an Asus HD4850. The problem can be repeated with the following steps:

1.) Load Windows Vista after shutdown and don't log into a user account
2.) Wait at the login screen and then time 15-30 seconds before pressing the power button (assigned to sleep on press)
3.) Wait 15-30 seconds before pressing the power button again
4.) If computer woke-up, check off success on paper and repeat steps 2-3. If not, follow to step 5.
5.) Hold the power button and shut down the computer manually. Logged how many tries before it "craps out" from wake-up.

Some system info: Windows Vista Ultimate 32-bit SP1, Catalyst 8.8, Samsung SyncMaster 710M LCD, Samsung SyncMaster 765MB CRT, Asus EAH4850 512MB, two DVI to VGA converters.

The expected result would be to have the computer wake-up no matter how many times the user put it to sleep mode from the login screen. The actual results are that it varies on how many "Sleep sessions" occur before the system becomes completely unresponsive and has to be shut down. My results showed that performing the previous steps @ 15 second intervals it would crap out between the 1st and 3rd wake-up attempt (tested 5 times). Performing them @ 30 second intervals would also crap out between the 1st and 3rd wake-up.

So far there's absolutely no link between how long I wait before waking-up and the number of tries it takes to crap out the Sleep system. Its still totally random. Any help?

Safe to assume youve applied all the latest updates/patches for vista? This is apparently a known issue, where the computer resumes from standby but the display doesn't. it doesn't seem to be limited to ati or nvidia cards.

[Edit 1.6] MS acknowledges some issues in dual processor machines, worth a try HERE

[Edit 1.5] Also, have you tried disabling the ati hotkey poller in services? that solve a few power related issues on an xp system for me, it might be worht a try for you as well, unless you actually use any ati-specific hotkeys.

[Edit 1.4] Are you using UAC? some report that disabling that can fix resume issues.

[Edit 1.3]
There apparently exists a fix, but i cant find a link to it yet.

Thanks for the help harmavoidance0, but I've honestly tried all those workarounds and fixes and have had zero luck with the problem. I also followed a thread from vistax64 and had no luck again.

And yes its safe to assume all my drivers are latest from the manufacturers of my parts. Here's a little more detail from the notes I've been keeping on my issue:


1.) Notes related to my issue:

2.) S1 and S3 are supported on my system:



3.) Devices allowed to wake up system:

I dont see it listed in your specs, what sound card are you using?

Also, ive been reading up on an unrelated forum, theres a tool called the "mce standby tool" that apparently solves these problems in xp and vista, but the downside is that you have to keep it running. It can be found Here

Some users have found that lengthening the standby time gives programs a better chance of ending properly.
