That is use to power the USB and other logic to enable the pc to boot. Disconnect other USB device on your pc.

One of the fans in the pc/server has failed and the bios has detected this and pops up a message during post for your information. The reason you can't do press a key, is probably your KVM is USB and the ports haven't been initialised, thus they aren't detected. You will need to replace the faulty fan or disable detection in bios as temp fix. | Report abuse shovenose Power supply Master June 2, 2010 1:53:20 AM i thouhght he said he replaced the fan? | Report abuse Register or log in to remove Ask the community Publish Tom's Hardware>Forum>Components>Keyboard and mouse not detected> Related ressources: Forum"No Keyboard Detected ", but all 3 of keyboard 's LED lights are open?!
