Mobile Computing Charging the battery 67 Wall Outlet-The fastest way to charge your tablet is with the included USB/AC adaptor plugged into a wall outlet. Charging the RTC battery Your device has an internal real-time clock (RTC) battery. The RTC battery powers the System Time Clock and BIOS memory used to store your device's configuration settings. When fully charged, it maintains this information for up to a month when the device is powered off. The RTC battery may have become completely discharged while your device was shipped, resulting in a CMOS error message during startup. The error message may vary by device model. NOTE Depending on your system, the RTC battery may only charge while the device is turned on. To recharge the RTC battery, plug the device into a live electrical outlet via the USB/AC adaptor and leave the device powered on for 24 hours. NOTE It is seldom necessary to charge the RTC battery because it charges while the device is on. If the RTC battery is low, the real-time clock and calendar may display the incorrect time and date or stop working. The device can be used while the RTC battery is being charged, although the charging status of the RTC battery cannot be monitored. Determining remaining battery power NOTE Wait a few moments after turning on the device before trying to monitor the remaining battery power. The device needs this time to check the battery's remaining capacity and perform its calculations. Touch the power icon in the notification area. (See "Finding your way around the desktop" on page 77 for more information on the notification area.) The window displays the remaining battery power as a percentage.

Charging the battery
Wall Outlet
—The fastest way to charge your tablet is with
the included USB/AC adaptor plugged into a wall outlet.
Charging the RTC battery
Your device has an internal real-time clock (RTC) battery. The
RTC battery powers the System Time Clock and BIOS
memory used to store your device’s configuration settings.
When fully charged, it maintains this information for up to a
month when the device is powered off.
The RTC battery may have become completely discharged
while your device was shipped, resulting in a CMOS error
message during startup. The error message may vary by
device model.
Depending on your system, the RTC battery may only
charge while the device is turned on.
To recharge the RTC battery, plug the device into a live
electrical outlet via the USB/AC adaptor and leave the device
powered on for 24 hours.
It is seldom necessary to charge the RTC battery
because it charges while the device is on. If the RTC
battery is low, the real-time clock and calendar may
display the incorrect time and date or stop working.
The device can be used while the RTC battery is being
charged, although the charging status of the RTC battery
cannot be monitored.
Determining remaining battery power
Wait a few moments after turning on the device before
trying to monitor the remaining battery power. The device
needs this time to check the battery’s remaining capacity
and perform its calculations.
Touch the power icon in the notification area. (See
“Finding
