Allegro DOS Owner’s Manual 83
In On/Off mode, the system clears and reboots when the On/Off key
is pressed. If external power is connected to the Allegro, the Allegro
goes into a semi-low power state where it appears to be off, but it is
actually on. Any event that normally causes the Allegro to turn on
(pressing the On/Off key, com port ring in, etc.) causes the Allegro to
reboot. When the external power is removed, the Allegro powers off.
Auto Suspend: Disable or 5 to 75 Minutes
If Auto Suspend is turned off, the Allegro stays on until you turn
it off or the batteries are drained. If Auto Suspend is assigned a
time limit, the Allegro turns off when the time limit passes with no
activity.
❖ Note: Lynx mode must be turned off to use Auto Suspend. Refer to
Setting up Communication, Adjusting the Allegro Communication
Parameters earlier in this chapter of the manual for details.
PC Card Suspend: On or Off
This setting determines whether the PC card remains powered on
when the system is suspended, allowing ATA Flash cards and other
I/O cards to operate in Suspend/Resume mode. If you are using one
of these cards and want to use Suspend/Resume mode, Select On for
this setting. For SRAM cards, this can be set to Off.
CPU Performance: Hyper, High, Medium, Low, Miser
This function sets the 486 processor clock speed for varying levels
of power/performance. When the processor runs faster, it requires
more power and drains the battery more quickly. For maximum time
between battery charges, set this function to the lowest level that still
gives adequate performance for your application. If battery charge is
not a concern, set Performance to High or Hyper.
Power Manager: On or Off
The Power Manager can help extend battery life by automatically
speeding up and slowing down the 486 processor based on system
activity. Activities include key presses, serial port transfers, and
video updates. The Power Manager should work fi ne for most
applications, but in some cases it may need to be turned Off. For
example, for applications that control their own power management,
we recommend that you set the Power Manager to Off.
