Using Low Battery Save to HDD and Instant On
I The ActionNote 890 series hard disk drive is partitioned at
the factory so that these options can be used. A 25MB area
is set aside for the saved data; this ensures that there is
enough space for all memory configurations.
I To prepare the hard disk drive, run the PHDISK utility,
located in the C:\PM directory. You also need to run this
utility if you upgrade your system memory. Type the
following command at the DOS prompt and press Enter:
PHDISK/CREATE
I If you install a new hard disk drive and
want to
use the
Low Battery Save to HDD or Instant On options, you need
to leave sufficient space on the disk unpartitioned. The
amount of space should equal the system memory plus
2MB. After you run FDISK to partition the drive, you need
to run the PHDISK utility to configure the storage space on
the drive.
I In Windows 3.1, when the computer is turned on after
using the Low Battery Save to HDD or Instant On options,
the PCMCIA services are not reinitialized. The computer
recognizes SRAM PC cards, but does not recognize most
other PC cards. You must reboot to reinitialize the services.
Using an External Monitor
When you connect an external monitor, make sure you turn it
on before you turn on the computer. The ActionNote
automatically detects the external monitor and displays data
on its screen. Press Fn F10 to switch your display from the
monitor to the LCD screen or to display on both screens
simultaneously.
Using a Serial Mouse
If you connect a serial mouse, you must use the Setup
program to disable the built-in touchpad.
