Clicking the battery icon on the Windows Taskbar Battery #1 refers to the battery pack inside the tablet computer. Battery #2 refers to the second battery pack inside the keyboard dock. Via the Battery Status (average remaining battery power of Battery #1 and Battery #2) in the Windows Mobility Center window When you use the tablet computer with the keyboard dock, the second battery pack is the first source to provide power. Wait several seconds to monitor the remaining operating time because the computer needs time to check the remaining capacity of the battery pack and then calculate the remaining operating time, based on this together with the current power consumption. Be aware that the actual remaining operating time might differ slightly from the calculated time. With repeated discharges and recharges, the battery pack capacity will gradually decrease. In view of this, it is noted that an often used, older battery pack will not operate for as long as a new battery pack even when both are fully charged. Maximizing battery operating time The usefulness of a battery pack depends on how long it can supply power on a single charge, while how long the charge lasts in a battery pack depends on: Processor speed Screen brightness System Sleep Mode System Hibernation Mode Display power off period How often and for how long you use the internal storage and external disk drives, for example, optical disc How much charge the battery pack contained to begin with How you use optional devices, such as a USB device, to which the battery pack supplies power Whether you enable Sleep Mode, which can conserve battery power if you are frequently turning the computer off and on Where you store your programs and data Whether you close the display screen when you are not using the keyboard - closing the display screen saves power. The environmental temperature - operating time decreases at low temperatures. User's Manual 4-18

Clicking the battery icon on the Windows Taskbar
Battery #1
refers to the battery pack inside the tablet computer.
Battery #2
refers to the second battery pack inside the keyboard
dock.
Via the
Battery Status
(average remaining battery power of
Battery
#1
and
Battery #2
) in the
Windows Mobility Center
window
When you use the tablet computer with the keyboard dock, the second
battery pack is the first source to provide power.
Wait several seconds to monitor the remaining operating time because
the computer needs time to check the remaining capacity of the
battery pack and then calculate the remaining operating time, based
on this together with the current power consumption.
Be aware that the actual remaining operating time might differ slightly
from the calculated time.
With repeated discharges and recharges, the battery pack capacity
will gradually decrease. In view of this, it is noted that an often used,
older battery pack will not operate for as long as a new battery pack
even when both are fully charged.
Maximizing battery operating time
The usefulness of a battery pack depends on how long it can supply power
on a single charge, while how long the charge lasts in a battery pack
depends on:
Processor speed
Screen brightness
System Sleep Mode
System Hibernation Mode
Display power off period
How often and for how long you use the internal storage and external
disk drives, for example, optical disc
How much charge the battery pack contained to begin with
How you use optional devices, such as a USB device, to which the
battery pack supplies power
Whether you enable Sleep Mode, which can conserve battery power if
you are frequently turning the computer off and on
Where you store your programs and data
Whether you close the display screen when you are not using the
keyboard - closing the display screen saves power.
The environmental temperature - operating time decreases at low
temperatures.
