Hi there, Can anyone help me? I'm quite desperate here. I'm having problem with my keyboard/USB. When I press any key on the keyboard, that instant all USB devices are disconnected. And soon after I unpress it, the system will detect all USB devices like they were just plugged in. I say all USB devices, cause it doesn't matter USB mouse or USB drive, they all get disconnected. It's frustrating me cause I can't use a USB mouse. Please help I'm using a Lenovo 3000 N100 0689GRA.
