Battery Power
NOTE

This computer prevents overcharging of the battery by recharging only when the
remaining power is less than approx. 95% of capacity after the battery is fully charged.
There are three methods to check the remaining battery power.

hibernation mode) (
NOTE
z
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.
z
The remaining battery power and remaining time indicated in the Windows battery
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

is calculated differently, so
displays may differ to some degree. This is not a malfunction.
