Computer Checkup (TEST) Error Codes
Computer Checkup (TEST) error codes occur if the system recognizes a problem while
running Computer Checkup. These error codes help identify possible defective
assemblies. Table 2-4 through Table 2-14 list Computer Checkup error codes, a
description of the error condition, and the recommended action for resolving the
condition. For removal and replacement procedures, refer to Chapter 5, “Computer
Removal and Replacement Procedures.”
IMPORTANT: Run Computer Checkup each time you complete a recommended action
step. If the problem is resolved when POST and Computer Checkup are rerun (in other
words, with no error codes), do not perform the remaining recommended action steps.
NOTE: The error codes in the following tables are listed in an “AYE-XX” format,
where:
A or AA = Number that represents the faulty assembly
YY = Test or action that failed
XX = Specific problem
Table 2-4

Memory Test Error Codes
Error Code Description Recommended Action
200-xx Memory machine ID test failed. The following steps apply to error codes 200-xx
and 202-xx:
202-xx Memory system CMOS checksum failed.
1. Flush the system CMOS and retest. See note.
2. Replace the system board and retest.
203-xx Write/Read test failed. The following applies to error codes 203-xx
through 215-xx:
204-xx Address test failed. Remove and replace the SODIMM memory board
or system board (if the memory on the system
board is faulty) and retest.
211-xx Random pattern test failed.
214-xx Noise test failed.
215-xx Random address test failed.
