power cord information.
To reduce the risk of electrical
shock, fire, or damage to the
equipment, do not use
converter kits sold for
appliances to power your
Notebook. Use only the
Compaq adapter that came
with your Notebook or a
Compaq replacement part.
Plugging and Unplugging AC Power
Do’s
• Ensure that you can reach the
electrical socket easily.
• Unplug the AC adapter from
the electrical socket when you
want to disconnect AC power
from your Notebook.
• To unplug from the electrical socket, grasp the cord by
the plug.
Don’ts
• Do not leave the AC adapter plugged into the electrical
socket when it is not connected to your Notebook.
• Do not place anything on power cords or cables. Arrange
them so that no one accidentally steps on or trips over them.
Surge Protectors
Using surge protectors and line conditioners can substantially
reduce the risk of electrical shock and aid in protecting your
Notebook from power-source problems.
During a power surge, the voltage level of electricity coming
into your Notebook can increase and cause data loss or system
damage. Protect your Notebook and peripherals by connecting
them to a surge suppresser, which absorbs voltage surges and
prevents them from reaching your Notebook.
<
Caution: High voltages can enter your Notebook through the
phone line connected to the modem. To protect your Notebook
during electrical storms, use a telephone line surge protector.
