Texas Instruments 3000 WinSX - Manual (Page 132)

Care and Handling of the Battery
Note: The battery is fully charged when the AC Adapter's amber light goes off and its
green light comes on and remains on for at least 1 1/2 hours.
q All batteries naturally discharge if unused for a long period of time. If
you are not going to use your TravelMate 3000 WinSX for an extended
period, be sure to recharge the battery every 3 to 6 months.
q When using the computer for the first time, or after prolonged storage in
temperatures above 95' F (35' C), a battery charge may not last as long
as normal. This condition disappears after a few full discharge/recharge
cycles. See "Conditioning the Battery" in Chapter 3 for details.
