Note:
The Extensa Series Notebook Computer User’s Reference Manual con-
tains descriptions of keyboard special function keys.
1.4.3.1 Controls and Indicators
The Extensa 57x contains a Power Button and a Status LCD just above the
keyboard. All notebook functions (except the power On/Off function) are
controlled by keyboard keys in conjunction with the
Fn
key.
1.4.4
Standard Power Features
Notebook power for the Extensa 57x Series Notebook Computers is provided
by an AC Adapter and a rechargeable nickel metal hydride (NiMH) battery
pack that installs in a power bay near the front of the notebook (right side).
A second lithium ion battery may optionally be installed in the Floppy Drive
bay when the Floppy Drive is removed from the Notebook.
All members of the Extensa 57x family feature a power management
subsystem (hardware and software) that provides for longer portable
operation and protection of files during low battery conditions.
n
Note
: The Nickel Metal Hydride (NiMH) battery requires periodic battery con-
ditioning in order to charge to full capacity. To accomplish this, remove the
AC Adapter and the secondary battery pack (if installed). Allow the notebook
to deep discharge. Then, recharge to full capacity. The secondary battery
pack is a Lithium-Ion type that does not require conditioning.
