4 – 3. System Diagnosis
System Diagnostics Card
The Diagnostics Card shows the system operations during the POST (Power On Self Test) in a 2 digit
hexadecimal number by connecting the cable to the 10 pin connector below the PCMCIA slot after separating
the Top part. The card is used to evaluate the reason for the malfunction without disassembling the system
when the system malfunctions and to test if the system operates normally after replacing a defective FRU.
X360 use Diagnostics card that is used for UMPC series.
Debugging Code
In general, if a defect of the circuit or part is detected during the system test, the system stops at a
particular code. The error codes for each part of the system are listed in the following table.
