I have a Windows7 laptop with two external 2.5" HDDs and a cooling pad connected through USB ports.
When I put the laptop to sleep, these devices are still powered on - the fan in the cooling pad is still spinning, the drives are still spinning.
I want to set it all up so that they power down when in sleep.

I tried setting the Allow the computer to turn off this device to save power option in the USB Root Hubs' Properties in Device Manager and enabling USB selective suspend in power options - it didn't work.

As it's a laptop, BIOS options are extremely locked down, so I can't even see anything relevant to sleep in there.

Is it even possible to do this?
