Mac Mini power/sleep light won't turn off.

Hi folks, I'd like to share my little problem with you [don't you just love to share?].

I have this Mini whose light won't turn off when I shut it down. It goes into *blinky-blinky* mode when at sleep but when I shut down it just stays on.

****
Even if I unplug it?!!!!!!!

I was thinking this maybe a hardware issue warning and that even if it isn't it could deplete the battery on the mainboard. So I thought that if its some kind of firmware I may be able to resolve it by reset the firmware blabla.

Do you people know any good sites for such kind of info?

I have no idea why that would be happening, but if there is a fix for it, you will find it here:

Well folks seems like I found out what causes this, although, I can't fix it.

It's caused by some USB hub with its own power. When I turn the mini off and disconnect the hub it will turn off.

weird!
