Battery Power
Check the Remaining Battery Power
There are three methods to check the remaining battery power.
Press the Fn+F9 key. (After logging on to Windows)(
Check the Windows Power Meter. (After logging on to Windows)(
Check the number of bright LEDs. (When the power is off or in standby/hibernation
mode)( page 39)
NOTE
In the following cases, there may be a difference between the remaining battery
capacity displayed on the indicator and the actual remaining battery capacity. To
correct this, perform the "Battery Recalibration." (
• The battery indicator light remains red
• The "battery remaining" displays 99% and the indicator light is orange for a long
period of time
• Low battery warning appears after a short period of time
This may be caused by the use of standby mode for long periods of time. The
battery is discharging while the computer is in standby mode when the AC adaptor
is not connected.
The remaining battery power and remaining time indicated in the Windows Power
Meter ([Power Meter] in [Power Options Properties]) are calculated based on the
computer's usage conditions at that time, so these displays may change when usage
conditions change. (These displays are only a guide)
The remaining battery power displayed using the Fn+F9 key is calculated differently,
so displays may differ to some degree. This is not a malfunction.
