Using The Function Buttons - Toshiba PSU9CU-00F00C User Manual

Power supply mode settings
There are two USB Sleep and Charge function modes. "Mode 4 (Default)"
should normally be used. Set "Alternate Mode" if the charge function
cannot be used in "Typical Mode(Default)". This function may not be able to
be used with some connected external devices even if the appropriate
mode is selected. In this situation, uncheck the "USB Sleep and Charge"
checkbox 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 before the setting, the "USB Sleep and Charge"
function will be stopped. Unchecking the "Enable under Battery Mode"
checkbox sets the utility to only charge when the AC adaptor is connected.
