Or better yet, find the little jumper inside on the motherboard and pull the little colored connector off of it and move it to short out the next pin on it and clear the cmos, it takes about 5 seconds and you wont have to take out the battery.It usually is by iteself and has 3 pins, 2 are usually connected, 1 isnt.Is usually labeled in super tiny print on the board itself.
That's harder to do, this way is equally effective
Step 1: Turn off the computer with the big switch on the back of the power supply
Step 2: Make good contact with the metal on your computer case, this is to make sure you dont have a static charge.
Step 3: Open up the computer case, and locate the BIG board.
Step 4: Pop out the battery, it looks like your average watch battery
