Notes on the LCD Brightness Control
The LCD screen brightness can be adjusted either manually or automatically.
Under certain operating conditions, e.g., very high ambient temperatures, your tablet
might automatically dim the LCD brightness in order to maintain a reasonable system
temperature. This is a normal protective feature and you might not be able to manually
adjust the LCD brightness during the auto dimming period.
Charging the Battery
When the battery power becomes low you must recharge it to avoid losing any
data.
Procedure
You can charge the battery when the tablet is either on or off by connecting the AC
adaptor.
■ Off
An icon shaped like an actual battery - a battery meter with flashing borders appears
in the center of the screen allowing you to keep track of the battery level. When the
battery is fully charged, the meter reaches its full capacity.
■ On
Likewise, a battery meter on the right side of the System Bar indicates the battery
level.
Charging time
The following table shows the approximate time required to fully charge a
discharged battery when the AC adaptor is connected to the tablet.
Charging time
Battery type Time
Battery (3 cell, 37.2Wh) about 8 hours
Please be aware that the charging time when the tablet is on is affected by
ambient temperature, the temperature of the tablet and how you are using the
tablet - if you make heavy use of external devices for example, the battery
might scarcely charge at all during operation.
Battery exhausted time
The following table shows the approximate exhausted time of a fully charged battery.
Battery exhausted time
Battery type Time
Battery (3 cell, 37.2Wh) about 12 hours (in use)
about 7 days (sleep mode)
Please be aware that the battery exhausted time will be affected by how you
are using the tablet.
