Checking The Remaining Battery Life - Fujitsu Laptop User Manual

Critical Point
The battery runs down in a relatively short time when it is used in a cold place.
The chargeability of the battery degrades over time and its life shortens accordingly after it
has been used over an extended period of time. If the battery goes dead soon, replace it with
a new battery.
A rise in battery temperature may slow down the operation of your computer. If this happens,
connect the AC adapter to your computer.

Checking the Remaining Battery Life

The remaining battery life is displayed on the operating status indicator LCD when the battery
is being charged or your computer is turned on.
Indication of the remaining battery life
The remaining battery life is approximately between 100% and 76%.
The remaining battery life is approximately between 75% and 51%.
The remaining battery life is approximately between 50% and 26%.
The remaining battery life is approximately between 25% and 13%.
(During charging, it indicates that the remaining battery life is approximately between 0%
and 25%.)
Indicates that the battery is weak (remaining life: 12% or less).
Indicates that the battery is completely exhausted (remaining life: 0%).
Critical Point
For reasons of lithium-ion battery properties, the battery life indicator may not correctly indicate
the remaining battery life under some circumstances (temperature conditions, number of
times the battery has been recharged, and so on).
When the battery is still 90% or more charged, it cannot be recharged even if you connect
the AC adapter to your computer. The battery can be recharged when its remaining life is
89% or less.
