Flip the laptop over. On the back, you will see a cover with a bulge on it, secured by 2 screws. It should be the biggest bulged cover on the back, the smaller one is the modem. Also, it should have the HDD symbol on it (couple of discs stacked or it may say HDD). Remove the screws and there it is. Remove any additional screw that holds the bracket in place, then gently pull sideways on the HDD until the pins come out clear. Only then, take the HDD out. Careful not to bend any pins.
