32 Chapter 1
Maximum input current (A,
@90Vac, full load) 2.25A @ 90Vac
1.125A @ 180Vac
Nominal frequency (Hz) 47 - 63
Frequency variation range (Hz) 47 - 63
Nominal voltages (Vrms) 100- 240
Inrush current The maximum inrush current will be less than 50A and 100A when the adapter
is connected to 115Vac(60Hz) and 230Vac(50Hz) respectively.
Efficiency It should provide an efficiency of 83% minimum, when measured at maximum
load under 115V(60Hz).

Power Management
Power Saving Mode Phenomenon
Standby Mode
Waiting time specified by the System Standby value
or the operating system elapses without any system
activity.
Or
When the computer is about to enter Hibernation
mode (e.g. during a battery-low condition), but the
Hibernation file is invalid or not present.
The Sleep indicator lights up
Hibernation Mode
When customized functions for power management
are set to Hibernation and the corresponding action is
taken.
All power shuts off
Display Standby Mode
Keyboard, built-in touchpad, and an external PS/2
pointing device are idle for a specified period.
The display shuts off
