In order to complete this project very few tools are required.
Philips Screw Driver (with a small head)
Flat Head Screw Driver (size doesn't matter, its used more as a pry-bar anyways)
Warning Before Attempting This:
This may void some warranties.
Step 1: Step 1 (optional): Remove Battery and Hard Drive
REMEMBER: Keep all of your screws organized and somewhere where they wont be knocked over.
Once the cover is out, the hard drive should be able to be removed. One end of the drive should be completely free and the other should be attached by a single plug. Unplug the plug and place the hard drive aside.
