CAPS lock light turning on when computer is off

[dredd2929]

When I turn my computer off, the CAPS lock light on my Saitek Eclipse keyboard keeps blinking, flickering, or staying on for a few seconds. There is no pattern, it just keeps turning on and off erractically.

Here's the pertinent specs:
PC Power and Cooling 1kW PSU
ASUS P5Q motherboard
Saitek Eclipse

I have everything plugged into an APC surge protector. I have no idea when this started; for all I know it's been doing this for a while, but I doubt it. Is this something I should be worried about?

Most motherboards have a bios setting that allows the USB ports to remain active/powered after shutdown. My guess is that your keyboard is buggy and its still getting power after the computer shutdown. I think the setting is something like +5vUSB, or USB standby, or something like that.
