I am in the process of repairing a Dell Mini 9 netbook. Apparently the keyboard seems to be stuck, as every once in a while it will an "a" will appear where I am typing, even when I am not pressing the a key. I have removed the keyboard and reinserted it several times. I pressed and held "FN + B" and then inserted the power and booted. After doing this and then powering the computer back down, the computer is silent when booting up (before it would beep like crazy and get hung). It will boot to Windows XP, but I might have plans for it to do something else OS-wise. What else should I try to prevent it from displaying an "a" when I am not pressing the a key? Thanks in advance for your help!
