The computer will turn on if the Esc/On key is pressed,
regardless of the options enabled.
To switch off:
press and hold the Fn key, then press the Esc/On key. Or,
tap the Suspend icon in the Start menu. You can switch
off at any time, but first save any open files.
Note: If you do not use the NETBOOK PRO, it will automati-
cally switch off after a few minutes to save battery
power. To continue using the NETBOOK PRO where
you left off, switch the NETBOOK PRO on again using
the Esc/On key. Power saving options are available
via the Control Panel/Power Properties/Power
Schemes menu. The automatic switch-off time may
have different settings, depending on whether the NET-
BOOK PRO is connected to an external electrical sup-
ply.
The NETBOOK PRO can be configured to turn off when the
case is closed. This is the default setting. See the Advanced
menu in Control Panel/Power Properties to disable the fea-
ture.

2.9 First Steps

When you first switch on the NETBOOK PRO, you will see
the Windows CE .NET desktop. At this time it is a good idea
to set the date and time. To do this, go to Start/Settings/Con-
trol Panel/ Date/Time Properties. The Date/Time Properties
dialogue box appears.
1. Set the Time Zone and click on Apply before
changing any other settings.
2. Set the desired date and time values.

3. Click the OK button in Time/Date Properties
menu to close and save your changes.

2.10 Power Management

The NETBOOK PRO is powered by a lithium-ion rechargea-
ble battery pack. The NETBOOK PRO will warn you when
the main battery charge is low.
Note: How long your batteries last will depend upon how
you use your NETBOOK PRO. The NETBOOK PRO
will use considerably more battery power when you
have the brightness turned up, are using files stored
on a memory card, or are using infrared or a
communications card.
You can take steps to help prolong your battery's life:
• Turn the screen brightness down.
• Set automatic switch-off in the Power menu.
• Use files on the internal storage instead of a
memory card, as the NETBOOK PRO requires
more power to write to the memory card.
The NETBOOK PRO can be powered from AC when con-
nected to the AC adaptor. When the NETBOOK PRO is
powered from AC, it will also charge the battery pack.

2.10.1 Battery Calibration

In order to provide an accurate estimate of the remaining
battery capacity, the NETBOOK PRO must see a full charge/
discharge or discharge/charge cycle in order to learn the char-
acteristics of the battery and calibrate the battery gauge.
