If the Time Remaining for the battery is not correct
•
The Time Remaining is an estimate, not a precise value, and is based on the rate at
which the computer is using power at the moment. This value therefore depends on
your current task, and assumes that you will continue using power at the same rate
until the battery runs out. So, if you check the Time Remaining while the computer is
performing a task requiring a good deal of power (such as reading from a CD or
DVD), the value will probably show less time remaining than you really have, since
you will probably later switch to tasks that require less power.
