Trackpad, Keyboard, USB mouse/keyboard don't do anything
I can boot using the power button, and I get to my login screen, but I can't move the cursor with the onboard trackpad or keyboard or with any USB device. Curiously, if I plug in a non-input USB device like a hard drive or an optical drive, it does draw power from the computer.
