To interpret the power and battery lights

Power Light (on hinge)
Steady green light.
Blinking light.
No light.
If ac power is off, a blinking light indicates that the OmniBook is in Suspend mode.
Battery Lights (on battery). The battery itself has four square lights that indicate
charge status when you press the square black button on the battery. Each light
represents 25% charge.

To replace the battery

You may never need to replace the rechargeable battery in ordinary use. Just
connect the ac adapter to the OmniBook and recharge the battery while you work.
However, you can replace a low battery with another that is more fully charged.
Caution
If you have any unsaved data, it (and your current work session) will be lost
when you remove the battery, unless the computer is connected to ac power
or a secondary battery is installed.
Do not mutilate, puncture, or dispose of the battery in fire. The battery can
burst or explode, releasing hazardous chemicals. A rechargeable battery pack
must be recycled or disposed of properly.
1. Important
Save your work. Turn off (Start, Suspend) the OmniBook.
2. Plug in the ac adapter. (If you do not, the computer will restart when you turn it
back on.)
Meaning
