Hi, I have a problem with my Toshiba Laptop keyboard. Satellite A200-192 It starts typing Z or / or \ by itself. Sometimes it is ZZZZZZ (tens of Z) of \\\\\\\ (tens of \). For example if I try to type "Hello" it will type as "Hezzzzzzzzzzzzzzzzzzzlzzzzzzzzzlzzzo". Sometimes the up arrow or down arrow or pagedown is pressed continously. I have Norton Antivirus. I have run 10-20 antivirus, spyware and Malware tools. They could not find anything. In a forum they said that this might be a Keyboard hardware problem. The KEYBOARD is NOW ultimately shutdow....Presently i am using a external keyboard, but now and then the right click of the mouse is activated.... Can you please let me know what should be done?
