Hello,
I have a problem with my keyboard I have a Toshiba Satellite A135-S2286 laptop around two years old it has functioned well with little problem until now the keyboard was wiped down with a dry cloth but the laptop was left on several keys were pushed all at once and it started beeping as if some function was activated it was shutdown and restarted after restart the number keys from 5 through 0 and the plus and minus keys no longer function also the letter keys Q . T . Y . U . I . O . H . no longer function it is as if they have been turned off I am now using the onscreen keyboard to type please help if anyone has any ideas I had a Dell Latitude notebook years ago and it did the same thing a friend at the time did something by pushing a combonation of keys and it beeped the keyboard worked fine after that again thanks for any ideas. my operating system is windows vista basic
