In the Windows 7 Power Options, under "PCI Express", I can adjust "Link State Power Management". The options are:
What do these settings do? Is there any reason to enable it when my laptop is plugged in?

Link state power management: PCI Express needs a continuous stream of data from the PCI Express device to the computer to keep them in sync. If the link state power management setting is set to conserve power the PCI Express device will basically power down and stop the continuous stream of data but it will need to power back up and sync before you can use it again.
