Exploring Your Computer’s Features
Using the eSATA/USB combo port
Using the eSATA/USB combo port
(Available on certain models.)
Your computer includes an eSATA/USB combo port, which can be 
used with both eSATA (external Serial Advanced Technology 
Attachment) devices and USB devices. The eSATA interface 
supports fast data transfer rates, which is especially useful for 
transferring and storing large files such as digital photo, music or 
video files. Like the USB interface, the eSATA interface supports 
hot swapping (connecting and disconnecting devices while the 
computer is on). eSATA devices require an external power source.
Your eSATA interface supports USB Sleep and Charge. For more 
information about USB Sleep and Charge, please se
Using the Ambient Light Sensor (ALS)
The Ambient Light Sensor (ALS) can sense light levels in the area 
of your computer and automatically adjust the brightness of the 
built-in-display, in order to improve screen visibility in low-light 
and high-light conditions
The ALS is enabled by default, but is automatically disabled when 
you are using the TOSHIBA eco Utility™.
To enable or disable the ALS function, click StartControl Panel
Hardware and Sound, and then Location and Other Sensors
Do not cover the ALS as the sensor will automatically adjust the 
computer's built-in-display’s brightness to low-light conditions. 
The ALS controls your computer's built-in-display's brightness. It 
does not control the brightness of external display devices.
