Warning!

Prevent static electric damage. Static charges can cause severe damage to microcircuits, but here are some easy ways to see that it doesn't happen:

• Don't touch edge connectors or exposed circuitry.

• If possible, ground your body. A metal power supply in your computer is generally considered the best place to ground yourself.

• Make as few movements as possible to avoid building up static electricity from your clothing, carpets and furniture.

1. Switch off your computer and all external options (printer, display, and others) and unplug all power cables from the electrical source.
   
   
2. Remove the cover mounting screws and save them for later.
   
   
3. Remove the cover of the computer.
