Checking operational charging

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 does not turn on, remove the battery pack and let it

return to room temperature. Reinstall the battery pack. If

the charge indicator or icon still does not turn on, replace

the battery pack.

If the charge indicator still does not turn on, replace the

system board. Then reinstall the battery pack. If it is still

not charged, go to the next section.

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.

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), 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 charge. 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, do the following:

1. Power off the computer.

2. Remove the battery pack and measure the voltage

between battery terminals 1 (+) and 5 (−). See the

following figure:

5(-)

1(+)

Terminal Voltage (V dc)

1 + 0 to + 12.6

5 Ground (−)

3. If the voltage is less than +11.0 V dc, the battery pack

has been discharged.
