Windows 7: Problem with sleep.

Home built computer running Windows 7 Utimate 64-bit. Intel i7930 - 6"GB Triple
Channel 3x2GB-2 - 2 Seagate Barracuda 500GB set to Raid 0 - and 2
additional 1TB hard drives. The computer has been running rock solid for
nearly a year.

Up until recently I have never used computer sleep, however, the way I use
the computer has changed, and I would like to set sleep to come on after a
delay of 30 Minutes. I set this up in Control Panel/Power Options/Create a
Power Plan.

Things work fine until I wake up from sleep - The problem is that the hard
drive indicator remains full on, doesn't blink just a steady full glow.
Everything continues to work correctly, I can use the internet and all the
software programmes that I've tried work.

Resetting the computer doesn't fix the problem a complete shut down and
re-start is the only way to get the hard drive indicator to show correctly.

Task Manager doesn't show any application’s being processed other than the
task manager - Processes doesn't show any disk activity.

I've turned sleep off and tried using the sleep button, the problem remains
the same.

Any help would be appreciated.

Check the ACPI settings in BIOS: Power Management Settings : BIOS for Beginners

Once the BIOS is set correctly with all ACPI-compliant hardware, the next thing to focus on is display adapter. Make sure you have the latest driver from the Support downloads webpage for the computer maker and/or adapter maker. Check all available drivers back to and including Vista. You can roll them back on Driver tab in Device Manager as well as "Look at a list" of available installed drivers.

Next check the Performance log to see if it is logging hangs at time of suspend: Win7 troubleshooting

I'd especially resolve all repeat errors in logs listed, run a clean boot to see if it will suspend, and clean up the startup list.

If this gets nowhere, use the tool used by the pros to troubleshoot these issues: Trace Windows 7 boot/shutdown/hibernate/standby/resume issues - MSFN

This tool solved all of my problems with sleep. Give a bit more fine control over things.
