Checking the battery pack

22
To check whether the battery charges properly during operation, use a
discharged battery pack or a battery pack that has less than 50% of the total
power remaining when installed in the computer.
Perform operational charging. If the battery status indicator or icon is not lit,
remove the battery pack and let it return to room temperature. Reinstall the
battery pack. If the charge indicator or icon is still off, replace the battery pack.
If the charge indicator is still not lit, replace the system board.
Battery charging does not start until the Power Meter shows that less than 95%
of the total power remains; under this condition the battery pack can charge to
100% of its capacity. This protects the battery pack from being overcharged or
from having a shortened life.
To check your battery, move your cursor to the Power Meter icon in the icon
tray of the Windows® taskbar and wait for a moment (but do not click it), and
the
percentage of battery power remaining is displayed. To get detailed information
about the battery, double-click the Power Meter icon.
Note: If the battery pack becomes hot, it may not be able to be charged.
Remove it from the computer and leave it at room temperature for a while. After
it cools down, reinstall and recharge it.
