P O IN T
The use of a weak battery may result
in lost of data you are currently working
on. When the battery runs low, connect
the AC adapter to your notebook as
soon as an external power source is
available or immediately save the data
you are working on, exit all applications
and turn off the notebook.
Accessing data on the hard disk
consumes a lot of power. Therefore
when the battery is weak, connect an
AC adapter to the notebook before
accessing data on the hard disk.
If a battery is weak and there is no
system activity, the notebook may
go into standby (i.e. suspend) mode.
However, if there is system activity, the
notebook will go into standby mode only
after the system activity has completed
its processing.
The notebook will go into standby mode
when the indicator reaches 3%. This is
the default setting of the notebook.
NOTE 1:
Battery temperature alarm is to stop
charging with battery protection function
when temperature of built-in battery pack or
extended built-in battery unit becomes too high
or too low due to battery heat or cooling down
of the battery.
