Charging The Battery/Ac Operation - Texas Instruments TravelMate 2000 User Manual

The AC Adaptor supplied with your TravelMate 2000 can be used to charge both the internal battery and the
optional Add-On Battery Pack, as well as to operate the computer on ac power,
Caution: Use only the AC Adaptor supplied with your TravelMate 2000. Using another
adaptor can damage your computer. Be sure to plug the AC Adaptor into a grounded outlet or use a
grounded plug adaptor.
It takes about 2 hours to fully recharge the internal battery with the power to the computer turned off. The
Add-On Battery Pack takes about 3.5 hours to recharge. The batteries are also being slowly charged while
you operate the computer on ac power.
A fully charged internal battery allows the computer to run for up to 2 hours. The Add-On Battery Pack
provides approximately 3 hours of operation and the add-on battery/internal battery combination can provide
up to 5 hours of operation.
NiCad batteries tend to lose capacity if they are never fully discharged. An unconditioned battery-one that is
brandnew, one installed in a computer that has not been used for a long time, or one that has sat uninstalled
for a long time must be conditioned before it will achieve maximum life. Otherwise, your battery will hold a
shorter charge than it is capable of holding.
To condition and charge the battery, follow these steps.
1. Install the internal battery if it is not already installed in your computer.
2. Allow the battery to fully discharge by using the computer on battery power.
