POWER MANAGEMENT OVERVIEW
Power Management in the NEC Versa lets you conserve energy, save battery power, extend the life of your LCD backlight, and protect against data loss due to low battery power. Set some features to function automatically or activate them manually with the keyboard or a button. It is wise to keep Power Management features enabled, even when using AC power. The system ships with many power-saving features already enabled. See the following table.
Table 1-5 Automatic Power-Saving Features
Device Idle Mode Standby Timeout Default Timeout On 4 minutes Comment Idle mode slows down the CPU during brief periods when the system is not busy. Specifies how long the system is in Idle mode before entering Standby mode. Standby turns off various system devices including the screen. This setting specifies how long the system remains in Standby mode before entering Suspend. Stops the hard disk motor when the hard disk is not accessed for the specified timeout. Shuts off video screen after the timeout specified elapses. Specifies how long the CD-ROM reader remains inactive before being turned off.

Technical Information

System Power Management
NEC Versa system power management consists of the following operation modes. These modes are:

T Active Mode · In active mode, the system uses no power management. It
operates with the default clock speed. The system continues to run at this speed unless overwritten by the power management features.

T Standby Mode · The system switches automatically to Standby mode.
This eliminates unnecessary power consumption when you operate the system on battery power or AC. Standby mode shuts down the LCD panel, providing privacy as well as power savings.

T Suspend Mode · Suspend mode causes the CPU to power down, local
devices to shut down, and register values to be stored in RAM. System RAM is put into a slow refresh state. The system resumes Active mode when you press the Suspend button, or the system is set to resume at a certain time of day. Suspend mode lets you save power without first saving the working data. Press the Fn-Esc keys simultaneously to enter Suspend mode when you need to be away from the system for a short period of time and want to return to where you left off. In addition, to quickly activate the Save to File feature, press the Fn-Power Button buttons simultaneously. This shuts down the system, and saves the current working data to a file.

Local Power Management
Use Auto Setup to select one of four power management settings for local devices. These include Longest Life, Maximum Performance, Customize, and Power Management Off. The power management levels are also available during AC operation. The NEC Versa computer ships with Longest Life as the default power management setting. See Section 2 for specific procedures on using Auto Setup to select the power management settings. When set to Longest Life, CMOS will set local device timeout values, a local standby timeout value, and a suspend timeout value to ensure the longest battery life. The Maximum Performance setting selects CMOS values that will provide minimal energy savings and a shorter battery life. The customize settings enable end-users to set the timeout values of their choice. The Power Management Off selection terminates all power management timers. Local device timers in the system control power consumption in the LCD and Hard Disk Drive. Table 1-6 shows NEC Versa Series Maximum Performance default power management timers.

PLUG AND PLAY
The NEC Versa features Plug and Play functionality. Plug and Play is the ability of the BIOS and/or operating system to dynamically assign system resources to a newly installed device without user intervention. For example, you can suspend the system, add a monitor or device to the VersaBay, and when you resume working, the NEC Versa recognizes the devices that have been connected to it. Similarly, you can remove external devices in Suspend mode and the NEC Versa detects the status when resumed. The NEC Versa is capable of having a keyboard or mouse added or removed while in the Power On mode. This capability is known a Hot Swap. Changes made while in Suspend Mode are classified as a Warm Swap.
