Compaq 1800 manual Maximizing Battery Operating Time, Battery Charging Time

Page 90

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.

7-6 CARING FOR YOUR BATTERY

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.
