PC-Diag Diagnostic Card
For use only in a laptop model computer with mini-PCI slot or LPT (printer port) connection. (Device must be powered by USB). User’s Guide
The Dual Notebook Diagnostic Card is a powerful diagnostic tool for technicians and administrators to troubleshoot various problems of notebook PC PII/III/ P4 by using a mini-PCI and LPT (printer port) Bus. It is easy to install, yet extremely powerful to use. With this card in hand, you no longer have to go through tedious and time-consuming process of trying to figure out what is wrong with your hardware. Notebook Diagnostic Card will indicate exactly what is wrong with your notebook in just seconds. It saves you r time and money.
Our new and improved design of Diagnostic Card, it can work with almost all popular types of CPUs, Motherboards, and BIOS.
All though we try, it is not possible to update this manual every time a new motherboard is made by the manufactures. It is always advised to visit the bios manufacture website, and download the latest codes per bios revision. Or visit bioscentral.com for an online reference.
The Dual Notebook Diagnostic Card itself only requires an empty mini-PCI slot or LPT port connection. It is not necessary to install memory chips to perform analysis. “POST Codes” can be
displayed through the hexadecimal display panel.
; Works with Laptop Only Motherboards
; Troubleshoot your dead motherboard.
; External display to easily view POST codes.
; Includes onboard speaker for BEEP codes
This product troubleshoots laptop style motherboard through the mini-PCI or LPT port. Your PC or NOTEBOOK may not support POST CODES from the printer port. Please check with PC or Laptop vendor before you purchase! This is the best tool for laptop troubleshooting. If you work on older laptop equipment, mini-PCI access is generally a guaranteed way to extract the bios code. If your fortune enough to be working on a newer laptop that support the LPT port for post code, this card work great for those as well.
Use this card to troubleshoot your motherboard problems. Sometimes your computer will not boot. Use this diagnostic card to see the POST (power on self test) codes that the BIOS commands the motherboard to perform. Each motherboard has a BIOS, which is a device that initializes all hardware components on the motherboard such as CPU, memory, video card, etc. During the boot up sequence, your BIOS will also generate what is called POST80 code. Each code can be referenced in a manual supplied to help determines the problem with the motherboard.
If your code is NOT LISTED in our manual, chances are you have a newer motherboard. Visit the manufacture of your BIOS and download the manual of your BIOS direct. In most cases, where the last post code is displayed on the POST card is generally the problem area. For example: If you have an Award Bios on your motherboard, and you install this card. Turn on the power to your computer. Your computer stops booting, but the POST card shows a code of "01". This could mean you have a faulty CPU on your motherboard because the BIOS told the CPU to start, but the CPU did not respond. If a piece of hardware does not respond during a boot sequence, then the motherboard will not finish POSTing. Kit Includes: 1 -

Dual Notebook Diagnostic Card INDICATORS
„Indicators‟ are any light emitting diodes (LED) or hexadecimal display panel is mounted on
extended cable. This section discusses the following indicators that appear on the Notebook

POST Code Display
The POST Code Display is made up of a dual; dot matrix hexadecimal read -out that displays Power

Power On Self-Test (POST) Codes
This card can test the AMI/AWARD/PHOENIX BIOS, while it can be used in wide model of notebooks. During system booting up, this card displays can show the post codes. Refer to Appendix A, it shows almost POST codes provided by BIOS manufacturers.
PCI Signal Definition:
CLK Motherboard Clock Signal. Should be on when power is supplied to the
motherboard even without CPU.
+3.3 Motherboard Clock Signal. Should be on when power 3.3V is supplied to
the motherboard even without CPU.
INSTALLING Dual Notebook Diagnostic Card
TO INSTALL A Diagnostic Card:
1) Install the Notebook Diagnostic Card in mini-PCI slot or LPT Printer Port 2) Power on the machine and monitor the code shown on LED
3) When using the LPT printer mode, USB cable must be used to supply power to PC Diagnostic card. USB cable not required when using mini-PCI slot mode.
The Feature of 4-Digits
-PCI or LPT Printer port
step by step.
-Checking Remote Display Function
1. Insert the post code card in PCI or ISA slot. Power on the machine. The post code will show on display. The left Post code display monitor the real time and right post code is for previous one. After the machine booting up complete, press S1 button about 2 seconds, then it can be checked the previous post code by pressing S1 or S2 button. 2. If S1 button is pressed 2 more seconds, it shows the testing speed rate which represents the PCI clock frequency. For example, if the display show F-33, which represent PCI clock 33 MHz.
3. If S1 button is pressed 2 more seconds for next stage, it has self -checking function from 0000 to 9999. To return original status is just by pressing S1 button again.
When the machine is turned on, the hexadecimal display should show the various POST codes (Post 80H + 84H) as the system executes (unless it has a rare BIOS that does not display POST codes).
If the machine does not boot, system POST has detected a fatal fault and stopped. The number showing in the hexadecimal display on the Notebook Diagnostic Card is the number of the test in which POST failed. Refer to Appendix A for a listing of POST codes.
Troubleshooting During POST
After initial power up, Power -On Self-Test (POST) codes begin displaying on the Notebook Diagnostic Card‟s hexadecimal displays (for most machines).
NOTE: A few machines use the parallel port to display POST codes instead of the Diagnostic Card.
THE POST PROCESS
The ROM built onto the motherboard of the computer rums its built-in POST (Power-On Self-Test) when you switch power on to the computer, press the reset button on the computer, or press Ctrl-Alt-Del (warm boot). POST performs a tightly interwoven initialization and testing process for each of these methods, but it typically does not test or initialize memory above 64K for warm boot. You can get an even better idea of the detailed process by studying the POST code listings in Appendix A.
