On some laptops, the screws on the underside are noted as to whether they are for the Keyboard or some other item, like hard drive. If they don't mark them, the first thing would be to visit the manufacturer's support web page and search for a manual for your model. I was there and I saw MANY different Presario 3000 models, so make certain you search for the correct model #.
Typically, however, the keyboard is kept on by 3-4 screws.
