Operation The battery
The battery
The notebook is fitted with a nickel metal hydride battery that provides it with power
during mobile use. You can increase battery life by enabling the notebook's power-
management features.
You can use the notebook with an additional battery. To do so, you must change
the built-in floppy disk drive against the additional battery. This will double battery
life in mobile use.
The battery charge is indicated by the BATTERY LED and the battery symbol in
the function display (see the section "Displays and input devices"). When you
switch on the notebook, it takes a few seconds before the battery status is
displayed.
The battery will last for roughly 500 charge/discharge cycles.
Deep-discharge and recharge the battery at regular intervals to utilize the
i
optimum capacity of the battery (see "Deep-discharging the battery").
Charging the battery
Only charge the battery when the ambient temperatures is between 5 ˚C and
35 ˚C.
When the notebook is not in use, the battery will charge in roughly two hours. If the
notebook is switched on, it will trickle-charge in roughly five hours. If the notebook
is fitted with two batteries, charging will take twice as long.
You can charge the battery by:
– connecting the notebook to the power supply unit
– connecting the notebook to the auto adapter
– connecting the notebook to a docking unit
– connecting the notebook to a station box
