Let see, pretty much you will have to tear your computer apart, I mean disemble it by taking the bottom cover, all the screws around the edge on the bottom, take the battery out, and there might be few smaller screw that needs to be taken out, then the optical cd-drive needs to be taken out, then there are like 2 or 3 small screw there located where the cd-rom slot is to be screwed off. Then on the other side, pry the top half of the laptop where the power button is off, then unscrew the screw holding the keyboard out, take out the keyboard, and slowly disconnect all cables to the keyboard. I'm not sure where the Cmos battery is located anymore since it's been 2 years since I took this model laptop apart, but then I think there some sticky cover near the palm rest that need to be pull out, and if I remember the cmos battery is there, if not it somewhere around the motherboard, but what you want to look for is a silver round battery that looks about the size of a nickel out. You'll have to take it out for a few minutes and then put it back it. This will allow a hard clearing of the Cmos bios which will reset it to original default value. Just becarefully since there is alot of screw and cable to take out to just to get to the battery.
