IT SUPPORT TO THE RESCUE

Windows XP and your Dell are more than capable of connecting an external keyboard. 9 times our of 10, the problem is the ps/2 to usb adapter. You should have one PS/2 port on that computer. Try connecting the keyboard directly into the PS/2 port and see if that works. If so, your problem is the adapter. If not, I would get myself a USB keyboard. Also make sure you have the latest XP service pack. That might ("might") help.

As for Seattle IT volunteer work. How much time do they need? I might be able to work something out. Email me with greater details.
