Power Management - Stand By and Hibernate
Power management settings can be found in the Windows control panel.
The following shows the power options properties in Windows ME. You
can define Stand By or Power Off for closing the display panel, pressing
the power button, or activating sleep mode. Basically Stand by and Hiber-
nate saves power when your Notebook PC is not in use by turning OFF
certain components. When you resume your work, your last status (such
as a document scrolled down half way or email typed half way will reap-
pear as if you never left. Power Off will close all applications and ask if
you want to save your work if any are not saved.
Stand By is the same as Suspend-to-RAM (STR). This function stores your
current data and status in RAM while many components are turned OFF.
Because RAM is volatile, it requires power to keep (refresh) the data.
Hibernate is the same as Suspend-to-Disk (STD) and stores your current
data and status on the hard disk drive. By doing this, RAM does not have
to be refreshed and power consumption is greatly reduced but not com-
pletely eliminated because certain wake-up components like LAN and
modem needs to remain powered.
Restarting or Rebooting
After making changes to your operating system, you may be prompted to restart the system. Some
installation processes will provide a dialog box to allow restart. To restart the system manually:
Click the Start button and select Shut Down | and choose Restart.
In case the operating system hangs (stops, freezes, crashes), try the following in this order:
1. Try a “warm boot” by pressing the [Ctrl][Alt][Del] keys simultaneously. (You may try a few times.)
2. If warm booting fails to work, you can press the reset button located in a small hole on the bottom
of the Notebook PC with a pen, mechanical pencil, or paper clip. (Do not use a standard pencil
because the tip may break off in the hole.)
Powering OFF the Notebook PC
For operating systems equipped with ACPI (Windows ME/2000), the Notebook PC can be powered
OFF by using Start | Shut Down... | Shut down. For operating systems without proper power manage-
ment (DOS, Windows NT), you must power OFF the Notebook PC by holding the power switch for 2
seconds (as opposed to 1 second to power ON) after closing applications and exiting operating systems.
This is necessary in order to prevent accidental power-OFFs.
