To Use Additional Batteries; To Get The Most From Your Batteries - HP OmniBook xt6050 - Notebook PC Manual

To use additional batteries

If your model supports a secondary battery, you can install a secondary battery in your
computer's plug-in module bay. See "Using Plug-In Modules" on page 76 for
information about installing plug-in modules.
For instructions on replacing the main battery, see "Step 1: Install the battery" on
page 21.

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 98 or 2000, use the lower speed on battery
power (the default settings conserve battery power)—see "How the computer
manages power automatically" on page 52.
• 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.
• 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.
• Install another battery—see "To use additional batteries" on page 57.
• If your main battery is rated at 11.1 volts (check its label), purchase a replacement
main battery, which is rated at 14.8 volts.
