The battery is a Lithium-Ion "smart" battery. It contains a temperature
sensor and a memory device that stores information about the battery, such
as how much charge is left and how many times it has been recharged. The
parameters for the "management" of the battery are also kept in the
battery's memory. The life expectancy will depend strongly on the care of
the battery, the individual usage pattern and the GoBook Tablet PC specific
configuration.
CAUTION Shutdown the computer and remove from external power before
removing the battery to prevent potential loss of data.
The battery pack is most efficient at room temperature. However, its
efficiency fails as the temperature varies from that range. The chart below
shows approximate capacity values with respect to temperatures.
To prevent damage, the charge circuitry is turned off for temperatures that
are too high (above approximately 115°F or 46°C) or too low (below
approximately 32°F or 0°C). Your GoBook Tablet PC is equipped with a
Thermal Grate to remove heat from the processor.
CAUTION The Thermal Grate gets warm during use of the GoBook Tablet
PC. Do not block the flow of air to the Thermal Grate.
NOTE A "cold-soaked" battery of 0°C only has about 10% capacity and
may not power a unit.
Monitoring Battery Power
There are two ways to monitor how much power the battery has left:
1. Hovering your digitizer pen over the battery icon in the
taskbar
,
without selecting anything, is the simplest way to check on battery
power status. The status will show as a pop-up.
2. Alternately, tap Start, Control Panel. If you are in Category View
select Performance and Maintenance, then Power Options. In Classic
View simply select Power Options. Then tap the Power Meter tab to
see how much battery power remains.
NOTE If you do not see the battery icon, enable it in Start, Control Panel,
Power Options. Choose the Advanced tab and select "Always show icon on
