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 overdischarged.
1. Turn off the computer.
2. Make sure that the 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 a new battery pack.
The battery operating time
indicated by the
Fuel-Gauge program or
the battery status indicator
is much longer or shorter
than the 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.
The computer does not
operate with a fully
charged battery pack
installed.
The over-current protective function in the battery pack might be activated. Turn
the computer off for 1 hour to reset the over-current protective function, and
then turn it back on again.
