Removing the case panels:

Next remove the Top and the side Panels on the computer. With this case I removed two screws from the top panel and then the side Panels slide up and out. You may have to use your screw driver and remove the screws that hold the Panels to the back frame of the computer and then side them towards the back of the computer. Check your computer manual on how to remove the Panels. If this is a new computer, there might be a sticker or piece of tape that says, if you cut this your warranty is voided, you may want to wait until your warranty period is over or call and ask if you can cut the tape to clean the computer. This is a picture of the Top and main Panels being removed.
