S3 Standby/Sleep not even available but S1 and S4 are?
I am testing Windows 7 RC on an old Dell Optiplex GX260 with a 3.06 Ghz CPU and about 1.5 GB RAM. So far I've been very impressed at how well it runs on this old box! My biggest challenge has been getting S3 Standby (Sleep) to work. Unlike most posts I've found on the net, my challenge is that S3 isn't even available. Note that S3 worked fine under XP. When I type "powercfg /a" it tells me that S1 and S4 are available but for S3 it says:
"The system firmware may support this standby state, but it does not work properly."
Some things I've tried:
I think it's great that the powercfg tool tries to tell you why a particular sleep state is not available but I'd love to know what triggers the code to spit out the statement that the firmware does not work properly? Is it getting confused by something? Is the 'check' for S3 more rigid now than in XP?
- I have the latest BIOS offered from Dell (A09- hasn't been offered for many years)
- Definitely made sure the S3 option is set in the BIOS (in fact, didn't make any BIOS changes from the settings that work fine under XP)
- Tried various Intel Chipset Drivers (845G) that I could find although it appears this driver has not been offered for a very long time (not surprisingly). I can get the old XP drivers from Intel to install and work fine but it doesn't alleviate the S3 option not being offered.
- Tried stripping the computer down to bare bones hardware without any PCI and other various peripherals attached (exception being the Logitech wireless keyboard and mouse plugged into the USB port)
- Tried various clean installs (not upgrades)
- The only thing that might be slightly less common is that I installed Windows 7 from a USB key rather than a DVD. I can't imagine this could trigger the issue but figured it was worth mentioning.
Any tips or suggestions for next debugging steps would be greatly appreciated.
