Windows 7: Change in Sleep Behaviour after re-install of Windows

Change in Sleep Behaviour after re-install of Windows

Further to my previous thread about problems getting PC out of sleep I have noticed a change in how the PC behaves when in sleep mode.
Before the re-install I am sure the PC became totally dormant, but now the system fans continue running (haven't checked CPU fan) and the power LED keeps flashing.
Or am I delusional?

It sounds like your sleep state is now S1, and previously it was S3.
Check your BIOS settings.

I use S3, and don't like S1 for the reasons you see...fans run, light blinking...
Here is a link about sleep states.

Thanks David.
During all my fiddling over the previous problem I must have inadvertently switched ACPI suspend from STR to POS.
Everything back to normal now.

If it's not Windows it has to be fingers.
