this mode. The system remains in auto-suspend mode until
activity is detected on a monitored device defined in Setup
or until the Auto Wakeup Interval (selected in Setup) expires.
When the Auto Wakeup Interval expires (5 to 20 minutes),
the system returns to normal operation for the duration of
the selected System Timeout Interval (1 to 15 minutes), at
which time the system again enters the auto-suspend mode.
Real-Time Power Savings
Your computer has a special power-saving feature that can
activate in real time while you are running your
application. This feature is implemented by a special device
driver called
BATTERY.PRO in the CONFIG.SYS file:
DEVICE=C:\UTILS\BATTERY.PRO [/Ln] [/Sn] [/MAP]
where:
/Ln specifies the power-savings level (0 through 4)
described elsewhere in this chapter. If the /Ln switch is
omitted, the default value of 2 is used.
/Sn similar to /Ln but tells the system what to use under
Windows when the computer is powered by AC. Mainly for
sound software that doesn’t use Application Program
Manager (APM).
/MAP moves the extended
BIOS data area within the base
640 KB system memory. The upper 1 KB of system memory
is mapped to provide a corrective 640 KB of system
memory. This
switch should be used with applications such
as
QEMM to enable them to manage the high memory area
more efficiently.
BATTERY.PRO must be the first device driver
in the
CONFIG.SYS file to effectively use this switch.
