What If Your Computer Does Not Work?
What If Testing Cannot Find the Problem?
If the test programs do not find the problem, use the following troubleshooting charts:
Battery Power Problems
Problem
Action
The battery pack starts
discharging automatically,
even if the AC Adapter is
connected.
When the AC Adapter is connected, and the remaining power of the installed
battery pack is less than a certain amount, discharging and then charging of the
battery pack starts automatically.
When you are using OS/2
or Windows, the message,
“Please discharge battery”
appears on the screen.
Discharge the battery pack; then recharge it (see page 100).
The computer does not
operate with a fully
charged battery pack.
Discharge the battery pack; then recharge it (see page 98).
If there is still a problem, have the computer serviced.
A fully charged NiMH
battery pack discharges
too soon.
The battery pack is either old or its operation time has been shortened by
repeatedly charging it when it was not completely discharged.
Action:
1. Check if the battery pack you are using has been charged for more than 2
hours by the power-off charging method.
2. If so, repeat the complete discharging and charging procedure three to six
times (see page 98).
Note: A fully charged battery gradually loses its power when not used for a
long period of time. If the battery pack is not used for a long period
of time, or if it is new, the battery does not reach full charge with
only one charging.
3. If the battery pack still discharges too soon, replace the battery pack with a
new one.
If there is still a problem, have the computer serviced.
The battery-power status
indicator has turned off
although a fully charged
battery pack is installed in
the computer.
The over-current protection device inside the battery pack has been activated.
Wait for several hours and try to use it again. If there is still a problem, replace
the battery pack or have the computer serviced.
