Before using wireless LAN/Bluetooth/Wireless WAN, make the appropriate security settings
such as data encryption.
Battery Recalibration
l
The battery recalibration may take a long time due to the large battery capacity. This is not a
malfunction.
<When performing “Battery Recalibration” after shutting down Windows>
Full charge: Approximately 4 hours (max.) (Approximately 3.5 hours (max.) for models with
Smart Card slot) (with CF-VZSU81EA)
Complete discharge: Approximately 3 hours (max.) (Approximately 2.5 hours (max.) for
models with Smart Card slot) (with CF-VZSU81EA)
When performing “Battery Recalibration” without shutting down Windows, it may take more
time to charge / discharge.
Sensors
This computer is equipped with four sensors (acceleration sensor, gyro sensor, magnetic sensor,
ambient light sensor), and you can use these sensors with any software that is compatible.
As the accuracy of each sensor output is dependent on the operating environment and other con-
ditions, the results should only be used as a reference.
The acceleration sensor, gyro sensor, and magnetic sensor are located under the keyboard. The
detection results of each sensor may vary depending on the display mode, how you are holding
the computer, the application software you are using, and other factors.
l
Display rotation
When the computer is in the Tablet mode, and the automatic rotation is on, the built-in accel-
eration sensor detects the computer’s inclination, and the screen display rotates automatically.
When an external display is connected, the display does not rotate.
Note also that some application programs may not support the primary and secondary Por-
trait angle display. For such programs, use the computer in primary or secondary Landscape
angle.
l
Automatic brightness adjustment
The computer is equipped with an automatic brightness adjustment function that adjusts the
display screen based on the ambient light sensor. You can configure the automatic adjustment
function as follows.
A
Display “Charm”, and click - [Change PC Settings] - [PC and devices] - [Power and
sleep], then set [Adjust my screen brightness automatically] to [On].
A
Click (Start) - [Control Panel] - [Hardware and Sound] - [Power Option].
B
Click [Change plan settings] for the power plan currently used.
C
Click [Change advanced power settings] and double-click [Display].
D
Double-click [Enable adaptive brightness], make necessary settings, and click [OK].
Set each item to ON, and the brightness of the screen display will adjust automatically.
The ambient light sensor is located at the top of LCD.
The ambient light cannot be detected properly if this area is obstructed or dirty.
