Operating Basics
Enabling USB Sleep and Charge
This utility can be used to enable and disable the USB Sleep and Charge
function in groups. USB Sleep and Charge compatible USB ports are
assigned to each group.
Check the check boxes for each group to enable the USB Sleep and
Charge function for the USB ports assigned to that group. In the default
state all groups are disabled.
Power supply mode settings
There are several USB Sleep and Charge function modes.
"Mode 1" should normally be used. Set one of the other modes if the
charge function cannot be used in "Mode 1". The selected charge mode will
be applied to all groups.
Some groups may be grayed out and not able to be selected for some
modes. This indicates that those groups are not compatible with the
selected mode and the USB Sleep and Charge function cannot be used.
In this situation, either select a different mode, or set one of the selectable
"Groups". This function may not be able to be used with some connected
external devices even if the appropriate group is selected. In this situation,
uncheck the check boxes for each group 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. Checking 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.
