Figure 1-3. Indicator Panel

The portable computer has nine indicators: six on the display assembly's indicator panel and three on the keyboard assembly. Each of the six indicators on the display assembly has an identical pair of LEDs: one is visible on the indicator panel when the display is open, and the other is visible through an aperture on the outside of the display assembly when the display is fully closed. The subsections that follow describe the functions of the indicators.

Power/Suspend Indicator

The power/suspend indicator is a green LED. After the computer is turned on, the power/suspend indicator lights up constantly to indicate that the computer is receiving stable power. When the computer enters suspend mode, the indicator blinks once approximately every 8 seconds.

Diskette-Drive Access Indicator

The diskette-drive access indicator is a green LED. The indicator lights when data is being transferred to or from the diskette drive.

Hard-Disk/CD-ROM Drive Access Indicator

The hard-disk/CD-ROM drive access indicator is a green LED. The indicator lights when data is being transferred to or from the hard-disk drive or the CD-ROM.

PC Card Access Indicator

The PC Card access indicator is a green LED. The indicator lights when data is being transferred to or from an installed PC Card (also known as a PCMCIA card).

Low-Battery Indicator

The low-battery indicator is an amber LED. This indicator is used in conjunction with the speaker to indicate either of the following low-battery conditions:

• The first low-battery warning occurs when the main battery's charge has been depleted to 8 percent of its fully charged condition. The low-battery indicator turns on and the speaker emits five beeps.

• The second and final low-battery warning occurs when the main battery's charge has been depleted to 3 percent of its fully charged condition. The speaker beeps twice every 1 to 2 seconds for 15 seconds; then the system does a suspend-to-disk operation automatically before shutting down.

Charging Indicator

The charging indicator is an amber LED. The indicator turns on when the main battery begins charging and blinks to show the battery is fully charged.

Keyboard Indicators

The keyboard controls the operation of the numeric lock (Num Lock) indicator, the capitals lock (Caps Lock) indicator, and the Scroll Lock indicator, all of which are visible through apertures at the top of the keyboard. These indicators are associated with the <NUM LOCK> key, the <CAPS LOCK> key, and the <SCROLL LOCK> key; when lit, the LEDs indicate the active state of these keys.
