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.

Q25. What type of System BIOS is in the AN-4SLC/33 and how do I run the SETUP

program?

A25: The SYSTEM and VGA BIOS conform to Seiko Epson BIOS specifications in a

single 1024-Kb (OT) EPROM. It supports Shadow Ram. To run the SETUP

program, you need to briefly press the delete key when the AN-4SLC/33 is booting.

While the AN-4SLC/33 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

Rights

reserved " screen.

Q26. What Real Time Clock chip does the AN-4SLC/33 use?

A26. The Dallas RTC ( DS 12 7 ) chip, which includes the lithium backup battery, is

socketed on the system

and Bitcom

software are included.

Q2 . What about power management software?

A2 . On the AN-4SLC/33 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 over ride

any time set in the SETUP utility.

POWER SAVE FEATURES

Q29. Are there any special power saving features to help prolong battery life?

A29. 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 rechargable 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 3) System Timeout Counter. This is in addition to the "display timeout

option" discussed

previously with VGACONF.exe.

Q30. How do you manually put the AN-4SLC/33 in "suspend mode"?

A30. This can be accomplished by sliding the "Suspend/Resume" button to the right or by

closing the

AN-4SLC/33 LCD.

Q31. How do you "resume" the AN-4SLC/33?

A31. A keystroke should "wake-up" the AN-4SLC/33. Preferably, the spacebar should be

used.

Q32. What if the computer has entered the Standby timeout mode and a keystroke

doesn't bring it back to

normal operating mode?

A32: 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.

PSB No: S-0169

Page: 7 of

Q31. Any other power saving tips?

A29. One more - with the keyboard NUMLOCK on, use the keyboard command <Ctrl>-

<Alt>-<+/-> [ on the embedded numeric keypad ] to change the CPU speed from 33

MHZ to MHZ. This can save a significant amount of power and, with several types

of applications (such as word processing), will not appear to be appreciably slower.

COMPATIBILITY

Q30. How's the software compatibility with the Epson AN-4SLC/33?

A30. Very good. Almost every type of software that's been tried on the Epson AN-4SLC/33

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.

Q31. How well does the AN-4SLC/33 work with local area networks?

A31. Very well. Novell has certified the AN-4SLC/33 as a workstation and in- house testing

has been completed for several other networking environments as well.

MISCELLANEOUS

Q32. What is the difference between the AN-4SLC/25 and the AN-4SLC/33 notebook

computers?

A32. There are a few minor differences between the two models as listed below.

The AN-4SLC/33 motherboard has a 4 6SLC/33 CPU, a crystal oscillator running at

66.67 MHZ,

and a resistor and capacitor has been added.

PSB No: S-0169

The variable speed math coprocessor from Intel only goes up to a speed of the 25 MHZ.,

therefore we only recommend the Cyrix CX 3S 7-33 math coprocessor for use in the AN-

4SLC/33.

Additional configurations have been made available with the 33 MHz version. Unlike

the 25 MHZ

version we are offering a 170 MB configuration (without a 2400/9600 data/fax

modem ) and 170 MB

configuration (with the 2400/9600 data/fax modem).

Although the AN-4SLC/25 and AN-4SLC/33 LCD's are functionally equivalent, the

AN-4SLC/33 LCD

assembly has a separate p/n of 2010993/33 whereas the 25 MHZ LCD assembly is

2010993. This is

because of the label that is on the LCD. The 25 MHZ version says ActionNote

4SLC/25 and the

33 MHZ version says ActionNote 4SLC/33.

Q33. How do I get an external keyboard or numeric keypad to work ?

A33. You must have external keyboard/mouse adapter attached to the port for the

keyboard or numeric keypad to work. Attach the keyboard or numeric keypad to the

bottom connector with the keyboard

icon on it. With the Epson numeric keypad, you must use the "pigtail" that comes

with the option and

you must hit the numlock key on the keypad if numlock is not on at boot.
