Some advice on Sleep problems please
I had given up on sleep working right. I can put it to sleep using a shortcut but then during the night it would wake. I finally gave up on solving this.
Then 2 days ago I updated my soundcard drivers and that night the system went into sleep on its own and was still asleep when I got up. I thought "GREAT!". It didn't last though and last night it did not go into sleep on its own.
Other than trying out some software yesterday, the only thing different from the night before was that my USB connected printer was on. Could that have been the culprit? I don't really know how to check this. I did run the Powercgf -ENERGY command and posted below are the errors it notices. Could someone that understands this stuf take a look and offer some advice or a good troubleshooting guide for me?
Sincere Thanks
Jess

Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.
S1 Sleep Supported: true
S2 Sleep Supported: false
S3 Sleep Supported: true
S4 Sleep Supported: true
