Important Notes on Using a Battery Pack
Recharging and Discharging
Recharging will not start if the battery's temperature is below 0 C (32 F) or
above 45 C (113 F) for NiMH batteries and 40 C (104 F) for Li-ion batteries.
Also, during recharging, the recharging will stop if the battery's temperature
gets above 60 C (140 F). To avoid problems caused by temperatures, make
sure the battery is not too hot before you begin to recharge or discharge the
battery. Follow these general guidelines:
When the battery is being recharged, keep the notebook power off and
wait until it is fully recharged to achieve the fastest charge times.
When the battery is fully charged or discharge, allow a brief cooling
interval to maintain the charge capacity and extend the useful life of the
battery.
During recharging, in order to maintain fuel gauge accuracy, do not disconnect
the AC adapter before the battery has been fully charged.
After the battery has been fully recharged, do not repeatedly disconnect and
reconnect the AC adapter to charge the battery again. Doing so may damage
the battery pack or reduce its charge capacity and useful life potential.
Do not leave the battery completely discharged for too long as this may affect
the battery's performance.
A DOS utility named "4dischrg.com" is included on your Utility CD-ROM. It is
used to disable all system power saving functions and allow you to calibrate
the battery fuel gauge. Before running this utility, it is important that you save
all files and close all applications.

Problem Solving

If the difference between the actual operating time of a battery and the
expected operating time is too large, you can fully discharge and recharge the
battery several times to solve the problem.
