Running the computer on battery power
The computer contains a removable lithium ion (Li-Ion) battery
pack that provides power when you are away from an AC outlet.
This is the main battery. You can recharge it many times.
In addition to the main battery, you may also have a second battery
installed in the SelectBay. If you travel and need to work for many
hours without an AC power source, you may purchase a battery
module for use in the computer’s SelectBay, or carry additional
charged battery packs with you.
The computer has two other batteries: an internal backup battery
and an internal real-time-clock (RTC) battery. These are nickel
metal hydride (NiMH) batteries.
The backup battery provides the power to store information about
the system when you suspend the computer using the Windows 98
Second Edition Standby command or Windows NT Suspend
command. The backup battery maintains this information for up to
eight hours after the main battery discharges completely.
The RTC battery powers the RTC memory that stores your system
configuration settings and the current time and date information. It
maintains this information for up to a month while the computer is
turned off.
Charging the batteries
To charge the main battery while it is in your computer, plug the
computer into a live electrical outlet. The battery charges whether
the computer is on or off. It takes approximately three hours to
charge the battery with the computer turned off, or up to 10 hours
when the computer is on.
The main battery light (
) glows amber while the battery is
being charged, and glows green when it is fully charged.
