Enable under Battery Mode
You can enable to use Sleep function(s) only with the embedded battery
pack (without AC adapter connected) by marking the “Enable under Battery
Mode” check box and clicking the Apply button. “Enable under Battery
Mode” check box is not available when both of “Sleep and Charge” and
“Sleep and Music” are disabled. Even if “Sleep and Charge” or “Sleep and
Music” is enabled, if the remaining battery life falls below the lower limit of
remaining battery life setting, the Sleep function(s) will be stopped and your
device will no longer be charged or play sound. The usable time of Sleep
function(s) with battery depends on the device connected, the battery
charge capacity and the configuration/settings of PC.
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.
