Opening and Closing the Computer

When you access memory modules, add-on cards, and hard disks inside your computer, you need to remove and replace 
the top panel beforehand and afterward.

Opening the Computer

If you remove the top panel immediately after you shut down your computer, the internal components may be too hot to touch. Wait about one hour to 
let the components cool down before you attempt to remove the panel.

To remove the top panel

Shut down the computer and turn off all peripheral devices, such as a printer.

Unplug the computer and disconnect all peripheral devices.

Remove the two screws from the back of the computer.

Slide the top panel toward the back of the computer, lift the panel, and set it aside.
