Power Management Features
The power management features are designed to save as
much electricity as possible by putting components into a
low-power consumption mode as often as possible. This
low-power mode is referred to as “suspend” mode.
Full Power Mode
The WorkPad z50 operates in Full power mode when power
management is disabled and the AC Adapter is connected.
