Local Stand-by Mode
after a period of inactivity.
When the LCD times out automatically, it returns to active mode when system
activity resumes, (i.e. pressing a key or using the VersaTrack).
n
Suspend Mode
Automatic Suspend mode after a specified amount of time (default timeout is 10
minutes). This shut-down mechanism conserves system power while allowing the
user to return to complete the work at any time.
Or, the system can be put into Suspend mode. Press the suspend button located
below the power button on the system's keyboard assembly to initiate Suspend
mode. Press it again to resume Normal mode.
Suspend mode causes the CPU clock to stop, local devices to shut down, and
register values to be stored in RAM. System RAM is put into a slow refresh state.

Plug and Play

While in Suspend mode, the Plug and Play feature allows the user to add or remove an ex-
ternal mouse, keyboard, monitor, or diskette drive without damaging the system. When Ac-
tive mode resumes, the Versa P system recognizes the newly installed option.

Local Power Management

Use Auto Setup to select one of four power management settings for local devices. These
include High, Custom, Low and Off. The power management levels are also available dur-
ing AC operation. See Section 2 for specific procedures on using Auto Setup to select the
power management settings.
When set to High, CMOS will set local device timeout values, a local stand-by timeout
value, and a suspend timeout value to ensure the longest battery life. The Custom setting
enables end-users to set the timeout values of their choice. The Low setting selects CMOS
values that will provide minimal energy savings and a shorter battery life. The Off selection
terminates all power management timers.
Local device timers in the system control power consumption in the LCD and Hard Disk
Drive.
Some system components can be individually turned off
When the system is powered on, but not in use it enters into
CAUTION: Do not add an external mouse,
keyboard, or monitor while the Versa P is in Ac-
tive mode. This could cause system damage.
