Hi all,
I upgraded to Windows 7 when it was first released and for some reason cannot use the sleep function. My power options in the control panel are set to "Balanced." I've opened up every menu I can think of and changed the settings but can't figure out why I can only use hibernate. Any ideas?
Hello Jay, and welcome to Seven Forums.
You might double check you BIOS sleep state settings to make sure that you have S3 selected using STEP THREE in the tutorial below.
Power Options and Sleep Mode Problems - Vista Forums
As a test, disable hibernation and only have your power plan options set for sleep to see it that may help as well.
Hope this helps,
Shawn
Thanks Shawn. The command prompt brought up this message:
The following sleep states are available on this system: Hibernate
The following sleep states are not available on this system:
Standby <S1> The system firmware does not support this standby state. The VGAPNP.SYS display driver does not support standby. Please consult your hardware vendor for an updated display driver.
Same thing for S2 and S2.
I attempted to use the command prompt as your link stated to disable hibernation but it said I don't have permission even though I'm the administrator
What's weird is sleep worked fine when I was on Vista. I guess my video driver isn't good enough for 7.
Update your chipset, BIOS and other drivers. Use driver sweeper for the gpu + sound drivers.
Running a SFC /scannow in command line never hurt anyone in the end
Agreed, but this seems to be a driver issue.
Perhaps, but wouldn't the scannow command look for invalid drivers also and try to replace them with a native driver perhaps?
It would look for corrupt system files.
Thanks for the input guys. I ran the scan and it did not find any integrity violations.
Shawn, I didn't (wasn't paying attention) but did now. It successfully took the hibernate option away but Sleep was still greyed out.
If it makes a difference, some of the new Windows 7 Features like Aero haven't worked. When I search "aero" on the comp, it runs a diagnostic and comes up with "The current video card may support Aero with a driver that is compliant with the Windows Display Driver Model (WDDM). Contact the manufacturer of your computer or video card for a WDDM-compatible driver."
I contacted Sony to see if there are any updated drivers but there aren't.
