Checking the Status of the OmniBook

The main OmniBook status lights, located at the front-right edge of the display bezel at the top of the
display, indicate power status and drive activity. (These lights are on the LED strip cable.)
The keyboard status lights, located above the keyboard, indicate the states of the keyboard locks.
(These lights are on the VGA PCA for the OmniBook 4100, and on the motherboard for the
OmniBook 4150 Series.)

In addition, the battery module has five lights that indicate its charge level. To view the lights, you
have to remove the battery and press the pad on the back next to the connector. The number of lights
that turn on indicates the charge.
