Texas Instruments 51X - Manual (Page 38)

3.3.4 Responding to Low Battery Conditions
The computer generally will notify you when you are reaching a low battery
condition by the following actions:
•
Four short beeps per minute (unless battery warning is disabled)
•
The battery low warning is automatically disabled when the AC Adapter
is installed on the notebook, regardless of the charge condition of the
battery pack.
•
If the AC adapter is not plugged in within three minutes of a detected
battery low condition, the notebook enters Suspend mode (if low battery
suspend is specified in setup). When the notebook enters Suspend
mode, it issues one beep, saves contents of RAM to disk and powers
down the unit.
•
The Notebook returns to the normal operating mode when the power
switch is activated. The unit then recovers RAM information from the
hard drive and restores the unit to its previous "On" condition.
3.3.5 Minimizing Power Usage
The following actions can minimize power usage and protect your work
during the critical minutes before you shut the system down or replace on
the battery packs with a fully charged pack:
•
Press Ctrl-Standby to shut off the alarm (if its enabled)
•
Save RAM Disk (if using RAM Disk feature)
•
Press Standby/ Suspend button to put the computer in
Standby/Suspend mode whenever you are not actively using the
computer. This will save all your work and remember the application
and file you were previously using when you return to the On condition.
•
Power down the system if you do not need the computer
3.3.6 Recharging the Battery Packs
The battery pack may also be charged in the notebook as follows:
1. Install the battery pack in your computer (if not already installed).
2. Connect the AC Adapter as described in Section 2.
3. To fully charge the battery pack, leave it charging in the Notebook
until the Charge LED extinguishes (approximately 90 minutes).
