Field reports indicate that when some HP printers are attached to the parallel port, the
computer hangs/malfunctions during power on. Investigation has verified these reports.
This situation can be quickly diagnosed, and corrected by following the procedure
below.
Description:
When the HP Laserjet is powered on and the printer cable is attached to the notebook
the computer may hang or malfunction during power on.
Corrective Measure:
When the cable is not attached and the printer/computer are powered on to a ready
state and then the cable is attached, the units functions normally. The notebooks will
also power on properly if the printer/computer are attached and the notebook is
powered on first.
Conclusion:
The issue reported was easily duplicated on the AN-500C. However, the AN4SLC
varied depending on which BIOS version was being used. If the older 2.06s BIOS
version was installed, there was no problem. With the 2.07S version of the BIOS,
follow the power on procedure listed above.

(Normal is black characters on a white background).
Q18. What type of microprocessor does the ActionNote 4SLC/25 use?
A18. The ActionNote 4SLC/25 comes with either a TI (Texas Instrument ) or Cyrix
486SLC/25 microprocessor. This processor is an advanced 32-bit, X86compatible processor offering high performance and integrated power
management on a single chip. The 486SLC is 486SX instruction set
compatible and 386SX bus compatible. It features a 1KB internal,
two-way set associative cache. In the future, a 33MHz. version may be
offered.
Q19. Can I upgrade my ActionNote 4SLC/25 by using an Intel Overdrive Chip?
A19. The Intel Overdrive Chip is not compatible with the Epson ActionNote
4SLC/25.
Q20. What type of System BIOS is in the ActionNote 4SLC/25 and how do I
run the SETUP program?
A20. The SYSTEM and VGA BIOS conform to Seiko Epson BIOS specifications in
a single 1024KB (OT) EPROM. It supports Shadow Ram. To run the SETUP
program, you need to briefly press the delete key when the ActionNote
4SLC/25 is booting. While the ActionNote is counting the memory, you will
see a message to hit the ‘delete” key to run setup. If you pressed the delete
key, you will see the ‘BIOS Setup Program - AMI BIOS SETUP Utilities (C)
1990 American Megatrends Inc, All Rights reserved” screen.

Q21. What Real Time Clock chip does the ActionNote 4SLC/25 use?
A21. The Dallas RTC ( DS 1287 ) chip is soldered on the system board, which
includes the Lithium backup battery.
Q22. What software and documentation is included with the ActionNote
4SLC/25?
A22. Currently we are offering MS-DOS Version 5.00, MS Windows Ver 3.1, the
ActionNote User’s Guide, Quick Reference Guide, Reference Diskette,
Logitech Trackman Trackball software and User’s Guide.
If the unit was purchased with the optional internal modem, Winfax Lite and
Bitcom software are included.
NOTE: MS-DOS Version 6.0 will be included when available.
Q23. What about power management software?
A23. On the ActionNote Reference Diskette, under the Utils sub-directory you will
find the file VGACONF.EXE. One of the selections available in
VGACONF.EXE is the Standby Timer option. This feature sets the LCD
power shutdown time when there is no keyboard or display activity.
Whatever time is set by this option, will override any time set in the SETUP
utility.
Q24. Are there any special power saving features to help prolong battery life?
A24. Yes. One way to help prolong battery life is to select the “Advanced Chipset
Setup’ in the SETUP program and enable the Power Management Function
and the other is to manually put the computer is “Suspend Mode”.
The Power Management Utility in SETUP turns off the LCD and hard drive to
reduce battery drain when the system is inactive and running off the
rechargeable battery pack. The three devices you can select for the time of
inactivity timeout are 1) the Display Timeout Counter; 2) Hard Disk Timeout
Counter and 3) System Timeout Counter. This is in addition to the “display
timeout option” discussed previously with VGACONF.EXE.

Q25. How do you manually put the ActionNote 4SLC/25 in ‘suspend mode”?
A25. This can be accomplished by sliding the ‘Suspend/Resume” button to the
right or by closing the ActionNote 4SLC25 LCD.
Q26. How do you “resume” the ActionNote 4SLC/25?
A26. A keystroke should “wake-up” the ActionNote. Preferably, the spacebar
should be used.
Q27. What if the computer has entered the Standby timeout mode and a
keystroke doesn’t bring it back to normal operating mode?
A27. There are some applications that may intercept any keystrokes before they
can be seen by the system BIOS. You may have to disable the timeout in
SETUP (or VGACONF.EXE ) to use the problem application on battery
power.
Q28. Any other power saving tips?
A28. One more - with the keyboard NUMLOCK on, use the keyboard command
<Ctrl>-<Alt>-<+/-> [ on the embedded numeric keypad ] to change the CPU
speed from 25MHz to 8MHz. This can save a significant amount of power
and, with several types of applications (such as word processing), the system
will not appear to be appreciably slower.
Q29. How’s the software compatibility with the Epson ActionNote 4SLC/25?
A29. Very good. Almost every type of software that’s been tried on the Epson
ActionNote 4SLC/25 has worked as it should. You may need to experiment
with the different display options for a given package - some will work fine as
standard VGA, others will have a special option for an LCD display. You can
also experiment with reversing the display mode and enabling contrast
enhancements using the VGACONF.EXE utility found on the Reference
Diskette.
Q30. How well does the ActionNote 4SLC/25 work with local area networks?
A30. Very well. Novell has certified the ActionNote 4SLC/25 as a workstation and
in-house testing has been completed for several other networking
environments as well.

Product Support Bulletin
Subject: Proper Method for Running Benchmark and Diagnostics Programs
Date: 06/04/93
Page(s): 1 of 1
PSB No: S-0158
Originator: MWT
This bulletin describes the proper method for running any benchmark or diagnostics
programs. This applies to any computer system.
In most cases, the computer should be started using an MS-DOS boot diskette
that’s ‘clean’ - in other words, one with no CONFIG.SYS or AUTOEXEC.BAT files.
The appropriate executable can then be run, either from diskette or hard drive.
There will be some exceptions to the above rule. In attempting to benchmark or
troubleshoot any add-on that requires a device driver (CD-ROM, local area network,
etc.), obviously the necessary device driver(s) must be loaded. Also, some
programs will require a minimum number of FILES or BUFFERS to be defined in
the CONFIG.SYS file. Such programs will usually display this requirement if they
are run without the necessary CONFIG.SYS file.
For the most consistent results, use the absolute minimal boot configuration that’s
allowed by the hardware being tested.
