Energy Saving Functions; Energy-Saving Modes - Fujitsu Siemens Computers Lifebook E Series Easy Manual

Energy saving functions

The notebook uses less power when the power management features are enabled, which allows
you to work for longer before having to recharge the battery.
Never switch the notebook off with the Suspend/Resume button while the notebook is in
i
one of the energy-saving modes.
If you will not be using the notebook for a longer period, first switch the energy-saving
mode off and then press the ON/OFF switch.

Energy-saving modes

You can set two energy-saving modes with your notebook.
Suspend mode
In this mode (Suspend to DRAM/Standby) all current data (active programmes, files) are buffered in
the main memory and in Save-to-Disk mode (Save to Disk/HibernateMode) all current data are saved
on the hard disk. Then the notebook is switched off. After the notebook is switched on, you can
continue working from the point where you finished.
In Suspend to DRAM or Standby mode the power-on indicator flashes (1 second on; 3
i
seconds off).
Save to Disk/HibernateMode mode is not indicated.
Do not use an energy-saving mode when you will not be using the notebook for a long
time, switch it off instead.
When using an integrated LAN/Modem, a PC-LAN card or a PC modem card connection,
we do not recommend switching over to an energy-saving mode, as this may lead to an
interruption in the network connection.
When you press the Suspend/Resume button for more than 4 seconds, your notebook will
switch off.
If your notebook is in an energy-saving mode mode:
•
Do not connect any external peripheral devices.
•
Do not disconnect any external peripheral devices.
•
Do not attempt to switch the notebook on if the built-in battery is flat.
•
Do not change or remove the floppy disk, if inserted.
•
Do not add or remove RAM.
•
Do not add or remove a PC card.
Suspend to DRAM
In this mode the current data in the main memory (DRAM) is stored for as long as the notebook is
supplied with energy. If the battery is full, the data is stored for a matter of days. Without a battery
and without a power supply the current data is lost.
