WARNING: To reduce the risk of electric shock and damage to the equipment:
Do not disable any 3-prong grounding plug. The grounding pin on a 3-prong plug is an important safety
feature. Removal of the grounding pin increases the risk of computer damage. If you cannot fit the plug
into your electrical outlet, contact an electrician for information on having grounded outlets installed.
Use only grounded electrical outlets when plugging in your computer. These outlets should be easily
accessible at all times.
When connecting a power cord to a grounded electrical outlet, ensure that nothing rests on the power
cord.
