I kindly want to ask why the laptop keyboard always give key problems with many laptops that I have used. I am living at sea side near coastal area of Mumbai (India). In past I had HP netbook which similarly problem with the some keys of the keyboard not working. I then at that time sold that HP netbook and than purchased a laptop then the laptop was working fine suddenly after few months of use the "z-key" start to type itself at random times when I type a document or url in the browser . I had opened the laptop back screw and removed the keyboard from the laptop. But I don't know if the laptop keyboards are repairable ? I work as part time at home as computer hardware technician. I did removed the keyboard from laptop but before doing any further repair with keyboard is it possible that the keyboard pad and the keyboard plastic sheet which is sandwich between the keyboard will survive. And had anybody have heard or done laptop keyboard repair "random key " press repair successfully?
