The Floppy Disk Drive Access indicator tells
you a floppy disk drive is being accessed. The
Floppy Disk Drive Access indicator will flash
when your software tries to access a floppy disk
even if no floppy disk is installed.
PC Card Access Indicators
The PC Card Access indicators tell you when
an installed PC Card is being accessed. Card 1
is the bottom connector inside the slot and
Card 2 is the upper connector inside the card
slot. Type III cards are always Card 1 only.

The NumLk indicator tells you the internal key-
board is set in ten-key numeric keypad mode.
(See page 28 for more information on the numeric
keypad.)
You can activate the NumLk mode by

down the Shift key. Deactivate the mode the
same way that you activated it.

board is set for all capital letters. Activate the all

same way that you activated it.

is active. You can activate or deactivate the
scroll lock by pressing the
NumLk/ScrLk key.
Deactivate the mode the same way that you
activated it.
BATTERY
The Lithium ion battery is rechargeable, and the
operating time will vary depending on active
power management features and user activity
levels. If the internal Lithium ion Battery goes
dead, you must install the AC adapter or shut
down and install a charged battery.
(See page 49
for replacing the battery.)
The Lithium ion battery operating time may
become shorter than the reference value if it is
used under the following conditions:
■
When used at temperatures that exceed a low
of 5°C or a high of 35°C. High temperatures
not only reduce charging efficiency, but can
also cause battery deterioration. (The Charg-
ing icon on the Status Indicator panel will
flash when you try to charge a battery that is
outside its operating temperature range.)
■
The battery charging capacity is reduced as
the battery ages. If your battery is running low
quickly, you should replace it with a new one.
■
When using a high current device such as a
modem, a LAN card, the DVD/CD-ROM
drive, or the hard drive frequently.
Using the AC adapter will conserve your bat-
tery when using a high current device such as a
modem, a LAN card, the DVD/CD-ROM drive,
or the hard drive frequently.
