Operating Basics
Power supply mode settings
There are several USB Sleep and Charge function modes.
"Mode 1 (default)" should normally be used. Set one of the other modes if
the charge function cannot be used in "Mode 1 (default)".Change the mode
from Mode4 to Mode1 to find the suitable mode for your USB device to
charge.
This function may not be able to be used with some connected external
devices even if the appropriate mode is selected. In this situation, clear the
check box and stop using this function.
Battery Settings
This utility can be used to specify the lower limit of remaining battery life for
USB Sleep and Charge. Move the slider bar to specify the lower limit. If the
remaining battery life falls below the setting, the USB Sleep and Charge
function will be stopped. Selecting the "AC only" check box sets the utility to
only charge when the AC adaptor is connected.
Heat dispersal
To protect against overheating, the processor is equipped with an internal
temperature sensor which activates a cooling fan or lowers the processing
speed if the computer's internal temperature rises to a certain level. You are
able to select whether to control this temperature by either turning on the
fan first, then if necessary lowering the processor speed, or by lowering the
processor speed first, then if necessary turning on the fan. Both of these
functions are controlled through the Power Options.
When the processor's temperature falls within normal range, the fan will be
turned off and the processor operation returned to its standard speed.
If the processor's temperature reaches an unacceptably high level with
either setting, the computer automatically shuts down to prevent any
damage. In this instance all unsaved data in memory will be lost.
