1. LENOVO DIAGNOSTICS OVERVIEW
1.1 What is Lenovo Diagnostics?
Lenovo Diagnostics is a diagnostic tool that tests various devices in Lenovo computers providing feedback to the
users about their machines health. Lenovo Diagnostics is composed by Modules that allows performing diagnostics
for a group of devices and by Tools to create custom executions (diagnostic script), see detailed information about
each device (system information) and consult the results for the tests performed in a machine (Log History).
1.2 Understanding the diagnostics
Each module contains one or more tests that may be performed under one or more devices resulting in a diagnostic.
This structure is displayed in the image below:
When a diagnostic is finished, Lenovo Diagnostics displays the results for each performed test and create two results
codes resuming the test execution.
8
Lenovo Diagnostics v4.39.0 – User Guide
The tests on Lenovo Diagnostics may have the following statuses:
Passed
When the test algorithm is executed and no failure is found.
Failed
When the test identifies the diagnosed device is defective.
Warning
When the test indicates the diagnosed device may have some defect but the
result is not conclusive.
Canceled
When the test is canceled in the middle of test execution.
Not Applicable
When the test is not applicable for the selected device.
The generated codes are:
Result Code
Contains information about the machine serial number, system platform and test
execution status and date. This code is generated for each tested device.
Final Result Code
Contains information about the machine serial number, system platform and execution
date. This code reports also the module where the tests were performed and the tests
with failed status.
On the next section, you will learn how to use Lenovo Diagnostics to perform the diagnostics.
1.3 Data Collection
Lenovo Diagnostics tool perform collect anonymous data regarding tests execution for the purpose of improve
hardware's diagnostics. You are able to enable or disable that function in accordance to your preferences.

Quick Random Pattern Test
The test consists of filling the memory with a random generated pattern and then checking that the pattern was
correctly written. When checking, it writes the pattern's binary complement and checks again. The test is repeated
twice. By default, 15 random patterns are used, therefore, the test runs once for each of these patterns.
Advanced Integrity Test
The test is based on the March C- enhanced algorithm. This test consists of filling the accessible memory with a
pattern, checking it, and writing its complement in an 8 bytes block size (64 bits) and then checking it again. This
procedure is repeated twice, being the first one addressing the accessible memory from the highest position to the
lowest and the second time by doing the inverse path. This test is intended to cover Stuck-At Faults and some
Coupling Faults and Transition Faults.
Address Test
This test consists of writing each memory address its own address. After that, the algorithm reads the memory
previously written and checks if they still store their own address. This test is intended to cover any addressing fault
in the accessible memory range.
Bit Low Test
This test consists of filling the memory buffer with a pattern where all bits are 0 and then checking it. When checking
for this pattern, it writes its binary complement, and finally checks if the complement was stored accordingly. Such
process is repeated 4 times. This test is intended to identify the most serious Stuck-At Faults, some cases of Transition
Faults and some cases of Read Random Faults.
Bit High Test
This test consists of filling the memory buffer with a pattern where all bits are 1 and then checking it. When checking
for this pattern, it writes its binary complement, and finally checks if the complement was stored accordingly. Such
process is repeated 4 times. This test is intended to identify the most serious Stuck-At Faults, some cases of Transition
Faults and some cases of Read Random Faults.
Walking Ones Left Test
The Walking Ones Left Test consists of writing a pattern where only the rightmost bit is set (e.g. 00000001), then
shift this pattern to the left (e.g. 00000010) until the end of the size of a byte, writing it again at the same memory
25
Lenovo Diagnostics v4.39.0 – User Guide
address each time such pattern is shifted. Therefore, the test is intended to cover most of the Stuck-At Faults and
some cases of Coupling Faults, and also testing the data bus by confirming that every bit can be written.
Walking Ones Right Test
The Walking Ones Right Test consists of writing a pattern where only the leftmost bit is set (e.g. 10000000), then
shift this pattern to the right (e.g. 01000000) until the end of the size of a byte, writing it again at the same memory
address each time such pattern is shifted. Therefore, such test is intended to cover most of the Stuck-At Faults and
some cases of Coupling Faults, and also testing the data bus by confirming that every bit can be written.
Modulo-20 Test
The test consists of writing into an interval of 20 memory locations for each block with a pattern and filling all other
locations with its complement 6 times. Unlike the other tests, the Modulo-20 test is not affected by buffering or
caching, so it is able to detect most of the Stuck-At Faults, Coupling Faults, Transition Faults and Read Random
Faults that are not detected by other testing approaches.
Moving Inversions 8Bit Test
The test consists of filling the memory with the 8 bit wide pattern: 10000000 and then checking that the pattern was
correctly written. When checking, it writes the pattern’s binary complement (01111111) and checks it again. The
procedure described earlier is repeated 8 times, one for each pattern right shifted: 10000000, 01000000, 00100000,
00010000, 00001000, 00000100, 00000010, 00000001.
Moving Inversions 32 Bit Test
This test fills all the accessible memory with a shifting pattern, that is, a value which is binary left shifted as it is
written out through the accessible memory of every memory block. Once the pattern reaches 0x80000000 (a value
with the left most bit set to 1 only) then the pattern is reset to 0x00000001. After that, it checks the written values
and writes their binary complements, starting from the first memory address to the last one. Finally, the algorithm
checks the memory for the complements written in the previous step, being this checking starting from the last
element down to the first one. Such process is repeated 2 times. This test presents a more thorough approach
intended to cover most of the Stuck-At Faults and Transition Faults and some cases of Coupling Faults and Read
Random Faults...
Random Pattern Test
The test consists of filling the memory with a random generated pattern and then checking that the pattern was
correctly written. When checking, it writes the pattern's binary complement and checks it again. This process is
repeated twice. By default, 50 random patterns are used, therefore the test runs once for each of these patterns...
Random Number Sequence Test
The test consists of filling the memory with one different random generated pattern for each memory address and
then checking that the pattern was correctly written. In order to check it, the test must generate these numbers
based on a seed that may be reset to reproduce the sequence. When checking, it writes the pattern's binary
26
Lenovo Diagnostics v4.39.0 – User Guide
complement and it checks again. Such process is repeated several times. This test is intended to cover most of the
Stuck-At Faults. Coupling Faults, and some cases of Transition Faults and Read Random Faults.
Block Move Test
The test consists of moving memory data around within memory blocks. It repeats the movements described above
80 times. Finally, the test checks every memory address to verify if it is consistent.
Nibble Move Test
This test consists of writing to a nibble (a nibble is a group of four bits) a pattern value in each memory address,
then it validates every nibble individually. It repeats this process until all nibbles in every address are checked.
