My computer won't POST + Logitech Illuminated keyboard

[mrochester]

Hello

My computer won't POST unless my Logitech Illuminated keyboard is connected to one specific USB port on the back panel of the motherboard. Even then, no other device can be plugged into the second USB port at the same time. I have now run out of USB ports. Has anyone got any idea why this would happen, and how to resolve it? I want to be able to permanently wire in my new iPad dock!

Many thanks

Michael.

I have connected a bluetooth dongle, monitor hub, mouse, remote control receiver, iPhone dock and the keyboard. I don't think any of them would suck much power other than perhaps the iPhone when docked and charging, and the keyboard, since it is backlit. I am beginning to think that the keyboard simply sucks too much power to work alongside another device.

Hi again

I'm still having this issue. Now I have to disconnect my iPad to get the computer to boot, but once it has POSTed, I can connect the iPad again, and everything functions as normal. What gives, why won't it boot with all devices plugged in?
