test. You may refer to the computer manual, check it from the CMOS chip on the

mainboard or the screen when system is starting, or contact the BIOS supplier.

The code meanings of this booklet are only for your reference.

2. The POST Code Table shows code values in ascending sequence, and

coding order on the card is decided by BIOS. Please pay attention that the POST

code values are usually continuous for common BIOS.

3. The mainboard pass the self test if the PC Diagnostic Card shows “FF” or

“00” after a series of codes. The mainboard doesn’t run if it stops and shows “no”,

“no-c” or “no-CPU” (“no” for short below). Is the CPU broken or is it correctly set?

Is the power supply normal? Does the battery goes moldy? Refer to the 2

clause of Chapter 10 for treatments when New Generation PC Diagnostic Cards

and Kingnostics Cards show “no”.

4. The PC Diagnostic Card shows normal when the mainboard which works

wrong, probably the reason is that you have set no warning on CMOS, so the card

will go on showing “00” or “FF” until it has found critical failure. Solution: Reset the

CMOS and make it give warning for all failures, and then restart the computer. The

PC Diagnostic Card will stop coding and show failure codes for all failures. The user

can make relative treatment according to the failure codes.

5. For the four digit PC Diagnostic Cards such as KPI4, KLPI4, KL4 and KLP4,

the kilobit and the hundreds on the LED show POST codes of the test computer,

and the tens digit and the unit digit show the one that is before the failure code, as

below:

Figure 1: Four Digit POST Code Display

For example: If the LED shows D0, D1, D2, D3, D4, D5, D6, D7, D8, D9, DA, Db,

DC and stops when testing a computer, the four digit card will show below as

Figure 2, press the check switch once, it will go on to show as Figure 3.
