What If Your Computer Does Not Work?
What If Testing Cannot Find the Problem?
If the test programs do not find the problem, use these 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 in 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 95).
The battery status
indicator has turned off
although a 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.
The battery pack cannot
be fully charged in 3
hours by the power-off
charging method. The battery pack might be over-discharged.
1. Turn off the computer.
2. Make sure that the over-discharged battery pack is in the computer.
3. Connect the AC Adapter to the computer and let it charge.
If the battery pack cannot be fully charged in 24 hours, use the new battery
pack.
If a Quick Charger (available as an option) is available, use it to charge the
over-discharged battery pack.
The battery operating time
indicated by the
Fuel-Gauge program or
the battery status indicator
is much longer or shorter
than actual operating time. Repeat discharging and charging of the battery pack at least three times.
The operating time for a
fully charged battery pack
becomes shorter. Repeat discharging and charging of the battery pack three to six times. If there
is still a problem, use a new battery pack.
