1-36 General Description
LED Displays
Caps Lock indicator. This LED indicates that the keyboard is locked in
the uppercase mode. To switch to the lowercase mode, press the Caps
Lock key.
Num Lock indicator. This LED lights when you press the Fn-F7
(NumLk) keys to toggle on the numeric keypad lock function. When the
LED is On, the embedded numeric keyboard keys generate AT-keypad
characters and functions when pressed in conjunction with the Fn key.
When the indicator is Off, pressing the Fn key with the appropriate keys
provides cursor movement, paging and other functions in the normal
mode. When the indicator is blinking, the embedded numeric keypad
becomes a temporary numeric keypad that does not require you to
press any other key.
Scroll Lock indicator. This LED lights to indicate that the keyboard is
locked in the scroll mode.
Power/Standby Indicator. This is a dual-color LED that glows green
when the Power switch is set to the On position. If the LED does not
come on, the AC adaptor may not be connected or the batteries may be
discharged.
Low Batt indicator. This LED glows red (and the alarm sounds if
enabled using the Setup Program) to warn of an impending low battery
condition (approximately 1 to 10 minutes of charge remaining in
battery). Both the alarm and indicator remain on until the computer
shuts itself down.
Floppy Disk indicator. This LED indicates the computer is reading from
or writing to the floppy diskette drive.
Hard Disk indicator. This LED indicates system disk drive activity, such
as when the computer is writing to or reading from the drive.
Turbo Indicator. This LED lights when the computer is operating in its
high speed mode. The LED extinguishes during reduced speed
operations, when the notebook is in Standby mode, or when accessing
the Floppy Drive and the Auto Speed mode is active.
