i've had two laptops so far, one twinhead and one toshiba portege. i experienced keyboard problems with both. the keys would get stuck and i would end up not being able to type anything. i would try to restart the computer but it would make this awful beeping sound (kind of like a particular key getting stuck) and it would refuse to do anything. for my twinhead, i tried having the keyboards replaced twice. i even had it reformatted once. it would work for a few months and then the same problem would reccur. i finally gave up on it. with my toshiba laptop, the technician just cleaned the keys and it went back to normal. but problem's back and i have no idea how to fix it. thecan someone please tell me why i keep on having the same problem?
