Hook up an external ps/2 (not USB) keyboard to your laptop and reboot your machine to see if windows may bypass your laptop keyboard on bootup. If it does and everything works fine then chances are the only thing affected by the fluid spill is the keyboard and youll at least be able to back up your data. New keyboards are about $60-$90 for new replacements. Have a geek install it for about $45. Most keyboards come out fairly easy from the top if you want to replace it yourself.
