Texas Instruments 3000 WinSX - Manual (Page 54)

Handling the Battery Pack
1. Install the internal battery pack in your computer (if not already
installed) as described earlier in this chapter,
2. Unplug the AC Adapter and use your computer on battery power. The
battery eventually will discharge and the Low Batt indicator will start
blinking. Save any work in progress and exit to the MS-DOS prompt.
(Press the Fn-Ctrl-F4 keys to turn off the beeper if it irritates you.)
You have from I to 10 minutes of battery charge life remaining. When
the Caps Lock, Num Lock, and Scroll Lock indicators come on, the
battery has reached the point where it does not have enough power to
reliably power the system and the computer automatically shuts down.
Every five to seven battery charge cycles, you should use the computer's
automatic discharge feature. Leave the computer on until all indicators
turn off. Ms deep discharges the battery pack. Otherwise, you can turn
your unit off now, or start recharging the battery.
3. To recharge the battery, connect the AC Adapter as described earlier in
this chapter. The AC Adapter's amber indicator glows while the battery
is fast charging. The green indicator comes on when the battery is at
least 90-percent charged. The green indicator turns on after about 3
hours of charging.
If the batteries are fully discharged and the amber indicator turns off less
than 2.5 hours after the start of a fast charge while the computer is
turned off, the batteries may need conditioning.
