When to Troubleshoot
Listed below are some tips on before parts replacement and after parts replacement. It is als o important to avoid replacing parts jus t in case,
or just to be safe.
Before parts replacement
1. Before opening a part's sealed packaging.
2. When you have received more than one part and are able to troubleshoot prior to
replacement.
Action:
Verify the failed component prior to opening sealed box or electrostatic bag. Check in a logical order b ut generally in the order of commodity
value.
For instance, if dispatched an LCD cable, inverter, and LCD panel--check
each in that order--working from the least expensive to the most expensive
item.

NOTE:
Troubleshooting prior to parts replacement is not always an option. Always follow regional process and dispatch instructions.
After parts replacement
1. When the dispatched part did not solve the customer's problem, it may be
necessary to troubleshoot.

Packaging: You should always verify you need to replace a part before opening its sealed
packaging. For many components, this is an electrostatic bag or envelope.
Is it the right part?: Often, there is enough information on the packaging to identify the partspecifically. For instance, if you are replacing a 450 watt power supply and the
replacement part's packaging label s ays it's a 250 watt-you have been sent the wrong part
and should not open it.

Labels: If you have been suppl ied with labels to identify unused or good/bad parts, apply
them prior to parts return. Different regions us e different labels . Here are some examples.Click high resolution image

Parts Return Process
Parts return process for EMEA (Europe, Middle East, and Africa)
All parts (opened or not) must be placed in an antistatic bag and returned to any PUDO by the technician the next day after the
intervention same as the parts used.

07/10/2012 Dell - On-Site Troubleshooting - Printer-Friendly Format
The Yellow Label is the normal Partner "Good Part" label. This label must be us ed in the following
circumstances only - "Use this label to return a part if the Outer packaging seal (box) is broken, but
the inner packaging seal (anti static bag) is unbroken".
This indicates to Dell that the part has not been used. Therefore the part is Good and does not
need to go through Dell's testing process .
The Red Label is the normal Partner "Defective" label. This label mus t be used in the following
circumstances only -"Use this label to return a part if both the Outer (box) and the inner (anti staticbag) packaging seals are broken".
This indicates that the part has been us ed and should go through Dell's repair and test process.
Use this label even if the part has only been used for diagnostic purposes.
If neither of the seals are broken (the part has not been removed from any packaging) then there is no need to fix either a Red or Yellow label. The part will automatically be returned as "Good".

oa
Avoid replacing CPUs needlessly. It is a good idea to keep in mind that processors rarely fail. Greater than
60% of all processor returns have "no trouble found". On many high volume products it is over 80%.
Applicable Products
All
Things you can do:a. Ensure through event logs (either in BIOS, or the OS) that the system is not shutting down due to
thermal issues.
If so, resolve the thermal issues by cleaning heat sinks.
Ensure fans are operational.
Thermal material is in place.
b. In systems that have an on-board speaker you should be looking for any beep codes. This means inducing a problem what would
cause the system to beep (for example removing memory DIMMS).
If the system beeps, the processor is performing basic functions and can likely be ruled out as the source of the issue.
If there are two processors in the system be sure to remove the 2nd processor when testing for beep codes. If you do
hear beep codes, swap proc 1 with proc2 and test again.
c. If unsure between the system board and the processor(s), replace the system board first.

No Boot / OS Not Found
Goal
Before requesting a repeat dispatch for a hard drive, run the hard drive self-test. Hard drive self tests are resident on the system board
in PSA diagnostics (Pre-boot Self Assessment) and do not rely on an operating system. Running PSA will take less than 6-7 minutes,
regardless of hard drive size.
Instructions
a. Power on system and press for BIOS.
b. Arrow down to hard drive field.
c. If HDD is not detected, reseat connector.
d. If yes, Power off and run the HDD Short Test, steps 5 through 9.
e. Power on the system.
f. At the Dell splash screen press until the one-time boot menu appears. The user
will be provided a menu.
g. Arrow down to "Diagnostics" and press . PSA Diagnostics is now launched.
h. At about 1 minute, 15 seconds from power up the user will hear a beep and be asked if colors are displayed properly. Press
for yes and to continue. The hard drive self test is running during this time.
i. A memory test will start and run in parallel to the hard drive test. This takes a few more minutes (approximately 5 minutes total).
When the memory quick test finishes the hard drive self test results are displayed.
j. If PSA says that the hard drive passes and the system will not boot, a likely problem is a corrupt or missing operating system.

System Slow / Shuts Down
Issue:
Overheating and intermittent shut down may be noticed on various Latitude, Inspiron, Vostro, XPS and Alienware systems due to
heat sink intakes or fan(s) getting clogged with dust and debris.The above issue is especially noticed on systems operating in a high dust environment.
Solution:
Clean the debris/dust clogged on the heat sink by blowing air directly into the fan exhaust port (either by blowing with mouth or
using some sort of canned compressed air).
The air must be sent directly into the heat sink port located on the side of the machine. This port is always on one of the sides or
back of the machine.
NOTE:
Limit duration of the compress ed air (short 2-3 second intervals), so as to avoid excessive spooling (RPM) of thefan.
On high performance machines such as XPS and Alienware, there may be more than one heat sink/fan.
If you cannot get compressed air into the exhaust port, place a vacuum hose to the intake port to extract the debris from the
bottom of the system. Limit the duration (short 2-3 second intervals) so as to not cause excessive spooling (RPM) of the fan.
Issue:
Insufficient Thermal Bonding
If the system's thermal solution has been disassembled, ensure that all thermal interface material is in place:
a. Between the CPU and heat sink
Either thermal grease or a thermal pad
b. Between the heat sink and the graphic processor units (GPU) - Portables Only
Ensure that the "colored" pads are in place.
GPU pads are different from CPU pads and are only supplied on replacement heat sinks. They are not separately
orderable. They are spongy and resilient, and can be reused. Shown here is a technician cleaning the CPU pad. To
the right is a red arrow pointing to a GPU pad. There can be several of these on some systems and they can be
green, white or blue.

Solution:
Replacing Thermal Material for Desktops and Servers
Under normal circumstances, Dell supplies thermal grease and an alcohol swipe in service kits.
1. Use the alcohol swipe to clean the old material from the processor and heat sink surfaces. You may need
to use a plastic scribe to remove hardened material.
2. Use the syringe to apply thermal grease in a swirl pattern as shown here.
Applying Thermal Pads to CPU/Heat Sinks
1. The thermal pad is located inside the white envelope. A cleaning pad is usually shipped with the thermal
pad; however, you can also use isopropyl alcohol and a lint free cloth.
NOTE:
The envelope can be easily mistaken for a label and thrown away. Always look carefully for the thermal pad inside the parts
package.

4. Repeat for the second liner. One side of the thermal pad is now completely exposed.
5. Place the exposed side onto the processor and apply even pressure across the pad.
6. Remove the remaining two liners and then assemble the heat sink to the processor.
NOTE:
You MUST remember to remove all liners prior to assembly.
Some portables us e thermal grease instead (for instance, ruggedized). Always use what is dispatched.

After Isolating PSU
At this point, you have tested the power supply (P.S.) and then subsequently plugged each component back into the power harness, yet you still
have a no post and no one component seems to be at fault.
Power Supply is Good. What Now?
At this point, you need to try and eliminate the I/O or control panel board.
I/O and Control Panel Boards
1. Remove any power connectors from I/O or Control Panel board and also disconnect these boards from the system board.
2. Remove the coin cell from the system board.

System Board Errors
After ensuring that the power supply, power supply harness, I/O or Control Panel boards are not the issue, we are left with the system board.
There are numerous LED and Power Button error code combinations. Below are the ones most commonly displayed when there is a systemboard failure.
NOTE:
One quick way to verify a bad system board is to remove the DIMMS. If 4 beeps are not heard during power on, the system board is bad.

Most Latitudes, PWS, XPS, Studio, Inspiron, Alienware and Vostro products have an LCD BIST. If there is doubt, boot to PSA diagnostics
(directions below). LCD BIST is on the system if the system runs a color bar test and asks "WERE COLOR BARS DISPLAYED?"(y/n).
What is in it for me?
Using an external monitor is NOT adequate troubleshooting. Running the LCD BIST will best determine if the LCD is functional.
There are two ways to run the LCD BIST:
1. Through PSA Diagnostics.
2. Standalone LCD BIST.
Through PSA (begin with system powered off)
1. Hold down FN key while pressing the Power Button. Release the keys when the DELL splash screen appears.
Another way: tap the F12 key during boot and arrow down to Diagnostics.
2. After about 45 seconds, the screen displays "WERE COLOR BARS DISPLAYED?" (y/n)
Intentionally fail it to initialize the LCD BIST (choose N). Flashing color patterns and loud beeps follow.This entire sequence takes less than 2 minutes, and the BIST portion itself lasts only a few seconds.
At the end of the test, a message appears: "Error detected, continue testing? Yes or No or Retry" This does not by itself mean the
LCD failed, remember the BIST was deliberately activated by pressing N (in step a).
NOTE:
You will always get the error codes 3-3-3 or 3-3-4 for deliberately having failed the BIST. When you get these codes, do not
replace any hardware.
If the color patterns do not appear, the beeps are very low or inaudible, or the video issue is clearly seen during the BIST (i.e.,
lines on screen), the LCD BIST fails and you can replace the LCD.
If the beeps and flashing color patterns appear without any distortion, the LCD should be fine. Do not replace the LCD. Provided
that software, settings, and other factors are ruled out, the root cause then could be the video card or motherboard.
3. Prior to LCD replacement, always check LCD cables for good connection. If in doubt, re-seat and re-check.
4. If you were shipped an inverter or converter board, they should be tried prior to LCD replacement. As with all multi-part dispatches, try
and eliminate the least expensive commodities first.
5. It is not typical to have multi-part failure. If the LCD BIST fails, do not replace the motherboard unless it also clearly fails a diagnostic test,
or thorough logical troubleshooting identifies some other fault with it. Avoid replacing multiple parts "just in case."
NOTE:
For the Latitude E-series, if the LCD BIST passes, but the PSA specifically fails only during the inverter test, you can replace just the
inverter.
Standalone LCD BIST (begin with system powered off)
1. Hold down the "D" key and press the power button.
2. The system will immediately launch the LCD BIST.
NOTE:
If LCD BIST does not launch, the system does not support this entry to LCD BIST. See Through PSA above.

ePSA Overview
Dell has introduced a new version of the Preboot System Assessment Plus (PSA+) Diagnostics called the Enhanced PSA Diagnostics. While the
PSA+ Diagnostics concept is not new, the functionality of the ePSA version is.
NOTE:
ePSA began shipping on new products, generally from March 2011, and is embedded in BIOS. For older products, a version of ePSA can
be used from a bootable USB key. Please refer ePSA on a USB Key for instruction and download files for the USB key version.
When launched, ePSA will automatically do a quick test of all system components in 5-7 minutes.
The following tabs provide an overview of the New features, steps to run the test and Modes in ePSA Diagnostics.
New features Launching ePSA Testing Devices using ePSA ePSA Diagnostics demons tration - Video
Dell ePSA (Enhanced Pre–boot System Ass essment) introduces the following new features over the existing PSA+.

For systems containing the diagnostics embedded in the ROM or on an internal storage, access them via boot menus.
Power the system ON and then press the F12 key (F10 on servers) during the boot process to get to the BIOS Boot Menu. It may be necessary to
repeatedly press the key during the boot process to get the BIOS to recognize the key at the correct time.
Use the keyboard up and down arrow keys to select Diagnostics on the menu and press the Enter key. ePSA begins by checking an area in
system m emory to ensure it is suitable for loading and execution. ePSA then loads itself into the verified memory area. Once loaded, ePSA beginshigh level diagnostic algorithms on all system m emory to ensure integrity. ePSA next creates a graphical menu lis ting all dis covered devices in the
system.
NOTE:
Once user exits the diagnos tics, a system restart may be required.
If you would like to use the diagnostics from external media, you will first need to create bootable USB key media (typically a USB key).
ePSA can be launched by any of the following methods -
Tap F12 during startup
Scroll down and select Diagnostics
or, Scroll to and select USB Storage Device (make sure the key is inserted first)
A Notebook Diagnostic menu is shown below -

The following lis t shows the tests that ePSA is capable of running. However, some tests are applicable to portables and som e to desktops.
Desktops and Notebooks ePSA screens have three (3) windows:
1. Device Tree Window
On the left side of each is a pale blue window called the Device Tree. This window dis plays all devices in the system and can be us ed to selectsystem devices.
2. Control WindowThe Control window is near the bottom-right of the screen. The Control window has a sm all check box labelled Thorough Test Mode. Checking this
box maximizes the intensi ty and length of the diagnostics. To the left is the Completion Bar which fills from 0% to 100% as tests run to completion.
The Run Tests button is clicked to start selected diagnostics. The Exit button will exit ePSA and allow a reboot of the system. At the lower-right is a
box with the ePSA Build version number.
3. Status WindowThe Status area is the large pale green window with selectable tabs. The tabs present depend on the system. Clicking these tabs will dis play thedata associated with the tab. Clicking on the tabs in the Status window wi ll show the following:
Configuration Tab - This window displays detailed configuration and s tatus information about all devices that ePSA has discovered about
the system.

8/19/2019 Dell - On-Site Troubleshooting - Printer-Friendly Format.pdf
34/64
System Health Tab - The System Health tab is usually the default tab that is active when the diagnostics are started and provides an up-to-
moment overview of how the system is performing. Typically, this display will contain information about the battery (or power supply), fans,
and thermal data. ePSA displays the Current reading along with the Highest and Lowest readings observed for the sensor.
Event Log Tab - This tab appears when the system contains at least one of the event logs that the diagnostics can detect.
The Status column contains a green check mark for informational items or a warning icon if the item needs additional attention.
The Source column indicates which log the item was taken from. EPSA can read:
BIOS - System log available on many notebooks and desktops
DIAG - Diagnostic log supported on many systems. Many diagnostic products can write to this log.
IPMI - Intelligent Platform Management Interface typically found on server systems.
DMI - BIOS log exposed via SMBIOS.
BSM - System BIOS log supported on some server systems.
SPD - Serial Presence Detect found on memory dimm s. The log depends on the BIOS.
The TimeStamp column helps to determine the order that the items were created in the log. Note that items are collected from m ultiple
sources, s o they may not be in order. Some event logs also have special values s uch as "boot time" that do not translate to a specific date
and time.

ePSA on a USB Key
ePSA on a USB key is used for older systems that do not have ePSA in BIOS. To know if a system has ePSA in BIOS, interrupt the boot sequence
with the F12 key and select "Diagnostics." If the system does not have the ePSA graphical user interface it has PSA. In this case you should use
ePSA on a key.
NOTE:
You will need to have local administrative rights in order to create the key.
Creating an ePSA key destroys any data already on the key.
ePSA on a key is not supported for release to customers at this time, it is only for Dell representatives.
Some customers may not allow a USB key on premises. In those cases, you must use diagnos tics available on the system or a
resource DVD.
Virus and Malware ProtectionIt is the technician's responsibility to protect themselves and the customer from viruses and malware when using USB keys. The key should be
scanned between uses. If there is any doubt about the integrity of the key, use the Key Creation process below to reformat the key.
TroubleshootingIf you run the key creation process and the key does not work:
You cannot call tech support, you must run through the Create Key process again.
If you suspect a bad key, use normal OS tools to format and write to the drive. If it works properly, run through the Create Key process
again.
The following tabs provide more information on ePSA Diagnostics.

Fan Speeds and Thermal Readings: These readings are different from model to model and we do not provide good/bad readings. For field
service, if the fans speeds show good variance, they are likely working properly. If you see varying CPU temperatures and they level off,
again, likely good.
The configuration tab is very useful for seeing what is installed.
You can select any commodity on the left and then run Extended Tests.

Depending on the system, PSA versions have a GUI look and feel very similar to the Dell™ 32-bit Diagnostics while others still have the same
text-based interface as the original PSA Diagnostics.
Launching the PSA+ Diagnostics
Launching the PSA+ Diagnostics does not change from the original version. There are two ways to launch this utility:
Hold down the key while pressing the power button to turn on the system.
Press at the welcome screen for the boot menu, and then select Diagnostics from the list.
PSA vs PSA+
Aside from the obvious differences of the look and feel discussed earlier, there are some other differences between the PSA+ Diagnostics and
the original PSA Diagnostics:
Version Numbering - PSA+ Diagnostics has version numbers starting with 4, as in: 4xxx. The standard PSA Diagnostics has version
numbers starting with 3, as in: 3xxx.
Error Numbering - PSA+ Diagnostics has error codes starting with a 2, as in: 2000-xxxx. The original version has error messages
starting with 1, as in: 1000-xxxx.
Initial Touchpad Check - PSA+ Diagnostics incorporates a touchpad check when launched, whereas the standard PSA Diagnostics
version does not.
MpMemory Algorithms - One of the most important feature enhancements for the PSA+ Diagnostics is the inclusion of MpMemory
algorithms for enhanced testing of the system memory. These algorithms are not present in the standard version.
Machine Check Exception Always On - PSA+ always has the Machine Check Exception feature on, which aids in troubleshooting
processor problems. Again, this feature does not exist in the standard version.
System Board Tests Consolidated - The original PSA Diagnostics has the different system board tests listed separately. These are now
all combined under one heading in the PSA+ Diagnostics.

PAIDPAID (Platform Advanced Integrated Diagnostics) is a method and set of tools used to improve the diagnostics capabilities
of Dell™ platforms. The goal is to provide improved tests and features that better detect and isolate problems for
customers and technicians. PAID features interconnect loopbacks, low-level control of LCD BIST, and a few other tools,
which are outlined below. Access the PAID features through the system BIOS and PSA and 32-bit Dell Diagnostics.
PAID is not a replacement for existing diagnostic tools. The POST, PSA, PSA+, and Dell 32-bit Diagnostic interfaces are used
and display the results of what PAID tests in the form of beep codes, LED codes, and error messages.
