Bad battery-- over charge When battery power is critically low, the OmniBook automatically shuts off, preserving your current status and all information. Before this occurs, however, you receive a battery warning message, and then the speaker beeps periodically. By connecting the ac adapter or installing a fresh battery, you can continue your work uninterrupted. Caution Once the OmniBook turns itself off, you have from several hours to several days to restore power or recharge the battery. Otherwise, the battery will run down completely, which can corrupt any open files.
Also, if you continue writing to a disk when the power warning period expires, you could corrupt open files if the battery runs down completely. After the warning period, the OmniBook automatically turns off to preserve your current session as long as possible—you won’t be able to turn it on again until you restore power. The battery is able to provide the small amount of power required to preserve memory for several hours or more. If you try to turn on the OmniBook again without restoring power, it beeps and refuses to turn on (to preserve memory). However, if you do this repeatedly, you will exhaust the remaining power and lose your current session.
To replace the battery If the battery goes bad (as indicated by the "bad battery" warning symbol ), you will need to replace the battery pack. 18
