IBM THINKPAD S05L-1270-01 - Manual (Page 655)

Diagnostic Error Codes
A detected error is shown as in the following example:
A large X to the left of the device icon
Device ID (three digit)
Error code (two digit)
FRU code (four digit)
The device ID and error code are used to indicate the
detail portion of the FRU that caused the error. If
replacing a FRU does not correct the problem, see the
device ID or error code from the previous failure. If they
have changed, the cause might be because the new FRU
is defective or that the FRU was incorrectly installed.
Device ID: If an error is detected by the diagnostic
tests, a three digits device ID is displayed. The device ID
indicates the suspected device:
