While laptops are wonderfully convenient, the portability comes with a drawback: a smaller hard drive than in an equivalently priced desktop PC. If you intend on installing a lot of programs or storing a lot of data on your laptop, you probably need to remove the old hard drive and install a new one. The process is quite easy, especially on laptops like the Dell Vostro 1000, a fast machine aimed at small business environments.
Turn off your Dell Vostro 1000 laptop.
Unplug the battery by pushing the buttons on either side towards the "Unlocked" position. A tiny open padlock icon imprinted in the plastic denotes this position.
Slide the battery free from its housing.
Turn the computer so it is resting upside down, with the screen hinge facing away from you. On the right-hand edge of the laptop, right below the battery housing, is the hard drive. Unscrew the two screws that hold it in place.
Pull the hard drive free by gently sliding it out of the laptop. It should disconnect rather easily.
