Notes on service and maintenance work
Only experienced electronics personnel should open the computer housing. Do not open the housing. It does not contain any parts that can be maintained by the user. Opening the housing will void the warranty. Always completely remove the power cable from the case when working with the hardware. Always ground yourself to remove static charges from your body before touching internal parts. Modern electronic devices are very sensitive to electrical charging. As a safety precaution, always use a grounding bracelet. Place all electronic components on a static-dissipative surface or in a static-shielded bag if they are not inside the housing.
