Texas Instruments 5000 - Manual (Page 87)

The Low Battery indicator glows red (and the alarm sounds if enabled
using the Setup Program) when the battery charge is low to warn of an
impending low battery condition (approx. 1 to 10 minutes of charge
remaining in battery). Both the alarm and indicator remain on until the
computer shuts itself down.
c
Caution: Update all work as soon as possible after the Low BAT indica-
tor comes on.
3.2.3.4 Battery Charge Condition LEDs
Each notebook battery pack has a set of four Battery Charge Indicator LEDs
along the front bezel and a Charge Display Button as shown in Figure 3-3.
The more LEDs on, the greater the remaining charge capacity on the battery
pack (all LEDs lit indicate batteries are 90 to 100% charged).
NOTE: When battery is 100% charged, all
LEDs extinguish; also LEDs extinguish when
battery is removed from unit.
