To Use Additional Batteries; To Get The Most From Your Batteries - HP omnibook xt6200 Reference Manual

To use additional batteries

You can install a secondary battery in your computer's plug-in module bay. See "Using
Plug-In Modules" on page 72 for information about installing plug-in modules.
For instructions on replacing the main battery, see "Step 1: Install the battery" on
page 20.

To get the most from your batteries

Follow these suggestions to make your battery's power last as long as possible.
• Plug in the AC adapter, especially when using a drive in the module bay, or any
external connections such as a PC Card or a modem.
• Set the display brightness to the lowest comfortable level (Fn+F1).
• Put the computer in Standby mode whenever you are not using it for a short while:
press the blue sleep button for approximately one second, or click Start, Shut Down
(or Turn Off Computer), Standby.
• Put the computer in Hibernate mode whenever you want to save your current session,
but will not be using the computer for a day or more: press Fn+F12.
• Set the automatic timeout settings to emphasize saving power. If your computer has a
multispeed processor and uses Windows 2000, use the lower speed on battery power
(the default settings conserve battery power)—see "How the computer manages
power automatically" on page 50.
• If your computer has a wireless on-off button, turn off the wireless function when
you're not using it. Press the wireless on-off button so the light turns off.
• Check that the display is using the Powerplay option. In Control Panel Display, on the
Settings tab click Advanced, then on the Powerplay tab check whether Powerplay is
enabled. This allows the computer to save power when it's not needed by the display.
• If you have an I/O PC Card—that is, a PC Card having an external connection, such
as a network card—remove it when you're not using it. Some I/O cards use
significant power even while they're inactive.
• If you work with an application that uses the serial port or an I/O PC Card, exit the
application when you finish using it.
