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 2.5 hours
Complete discharge: Approximately 2 hours
When performing “Battery Recalibration” without shutting down Windows, it may take more time to charge / discharge.
n
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 conditions, the results
should only be used as a reference.
The acceleration sensor, gyro sensor, and magnetic sensor are located at the bottom left of the LCD. The detection results of
each sensor may vary depending on how you are holding the computer, the application software you are using, and other factors.
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
Touch
(Start) - [Control Panel] - [Hardware and Sound] - [Power Options].
B
Touch [Change plan settings] for the power plan currently used.
C
Touch [Change advanced power settings] and double-touch [Display].
D
Double-touch [Enable adaptive brightness], make necessary settings, and touch [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.
l
Magnetic sensor
The magnetic sensor on the computer operates by detecting geomagnetism. Therefore, the magnetic sensor may
not function properly and it readings may be inaccurate, especially in the following environments.
Inside or near steel structures such as buildings or bridges
Inside or near automobiles, or near train power lines
Near metallic furniture or appliances
When the AC adaptor or other peripheral devices are brought closer to the computer
Near magnets, speakers, or other objects with strong magnetic fields
The magnetic directions indicated by the magnetic sensor may not be accurate immediately after purchase or in
environments with poor magnetic fields.
In such cases, turn on the computer and move it as follows.
A
Hold the computer so that its screen side is facing upward and level.
B
While keeping the computer level, rotate it 90 degrees or more clockwise.
C
Return the computer to position
A
, and rotate it 90 degrees or more counterclockwise.
D
Return the computer to position
A
.
E
Tilt the computer 90 degrees or more to the left so that the left side of the computer tilts down.
F
Return the computer to position
A
, and tilt it 90 degrees or more to the right so that the right side of the computer tilts down.
CAUTION
● Hold the computer firmly when moving it. Strong shocks from dropping the computer may result in damage.
Maintenance
If drops of water or other stains get on the surface of the LCD panel, wipe them off immediately. Failure to do so may result in staining.
To clean the LCD panel
Use the soft cloth included with the computer. (For further information, refer to “Suggestions About Cleaning the LCD
Surface”
è
Reference Manual
“Screen Input Operation”.)
To clean areas other than the LCD panel
Wipe with a soft dry cloth such as gauze. When using detergent, dip a soft cloth in water-diluted detergent and wring it thoroughly.
CAUTION
l
Do not use benzene, thinner, or rubbing alcohol since it may adversely affect the surface causing discoloration, etc.
Do not use commercially-available household cleaners and cosmetics, as they may contain components harmful to the surface.
l
Do not apply water or detergent directly to the computer, since liquid may enter inside of the computer and cause
malfunction or damage.
