4-2 Upgrading Your Compaq Internet PC
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.
To reduce the risk of electrical shock and damage to the computer, BEFORE
REMOVING THE COVER always ensure the following:
x
The computer is turned off.
x
The computer power cord is unplugged.
x
The modem line is disconnected from the telephone jack.
x

x
All cables and power cords are disconnected from the computer.
CAUTION: To prevent damage to the computer by electrostatic discharge, you must
become static-free before removing the cover. To become static-free, touch an
