    A friend of mine has an older HP desktop and is having a problem with it. She is getting a beep code 1-3-1-3 when she tries to boot it up. I know this is a phoenix bios beep code and the description in hp.com basically says to troubleshoot the keyboard, keyboard controller and motherboard.

    Can someone give me some easy to follow instructions on how to do this? I would like to take a look at it fo rher this weekend and would like to at least know a little bit about what I am doing.

    Explanation: The keyboard controller is a chip on the motherboard that communicates with your keyboard. It also controls the A20 gate that provides access to the high memory area (HMA). There is a failure somewhere in this part of the system.
