Help! I've got a problem with my laptop keyboard. The touchpad works fine but every time I try using the keyboard, everything freezes. Even the volume control buttons on the side of the laptop won't work. Right now the keyboards are disabled, saying that they've been disabled since the drivers may be corrupt or missing. I've been using the on-screen keyboard, but it's so hard to type documents. I hope you can give me advice on how to resolve this. Thanks much! BTW, my laptop's model is ze4908us (i mixed 8 & 0 on the title) ==sorry!
