HP Laserjet Printers Cause The ActionNote 4SLC series and ActionNote

500C Units to Lock-up During Power On When Attached.

Date: 07/26/95

Page(s): 1 of 1 PSB No: S-0185

Originator: AV

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.

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.

Subject: Proper Method for Running Benchmark and Diagnostics Programs

Date: 06/04/93 PSB No: S-0158

Page(s): 1 of 1 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.
