Solved Change in Sleep Behaviour after re-install of Windows

[HairyScot]

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...

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.

You're welcome.
Glad you got it sorted.
