Installation/Support Tips

Using Low Battery Save to HDD and Instant On

IThe 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.

ITo 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

IIf 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.

IIn 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.
