7-6 CARING FOR YOUR BATTERY PRESARIO NOTEBOOK BEYOND SETUP GUIDE
1800 SERIES
If you will not be using your
Notebook for an extended
period of time, Compaq
recommends that you unplug
the electrical cord from the
socket and remove the
battery while your Notebook
is not in use.
The battery will charge
whether your Notebook is on
or off, and will continue to
charge until the battery is
fully charged or AC power
is disconnected.

Battery Charging Time

Battery charging time will vary based on the initial battery
charge, the type of battery, and the activity of your Notebook
while charging.

Purchasing Spare or Extra Batteries

Over time, all batteries lose the ability to operate at full capacity
and the battery will have to be replaced. To purchase a new
battery, contact your Compaq-authorized dealer or access the
Compaq Web site at: www.compaq.com/athome.
Maximizing Battery Operating Time
The battery operating time depends on your power management
settings. Your Notebook components, the options, and the
applications that you use also affect the operating time. This
section of “Caring for Your Battery” shows you how to increase
the length of time you are able to operate under battery power.
The display, processor, CD/DVD drive, and hard drive use the
most battery power. To maximise the battery operating time,
perform one or more of the following actions:
•Reduce display brightness and select a short wait for your
screen saver.
•Select a screen saver that does not generate a lot of graphics
or motion.
•Reduce audio volume or use headphones.
•Exit modem programs when you are not using them.
•Remove PC Cards when you are not using them.
•Remove CDs or DVDs when you are not using them.
•Use Sleep or Hibernation mode to turn off your Notebook
when you are not using it.
