Checking the battery pack
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.
Tap the battery icon in the icon tray, and the percentage of battery power
remaining is displayed. To get detailed information about the battery, tap Battery
under Settings In the applications list, to enter the battery information interface.
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.
To check the battery pack, follow the steps below:

Turn off the computer. Follow the removal steps in "1020 Battery pack" on page 29
in "Removing and replacing an FRU" on page 26.
Measure the voltage between battery terminals 1 (+) and 6 (-). See the following
figure:
If the voltage is less than +3.4 V DC, the battery pack has been discharged.
Note: Recharging will be continued for at least 3 hours, even though the indicator
does not light on.
If the voltage is still less than +3.4 V DC after recharging, replace the battery.
