Dell T5810 Troubleshooting

Overview

The following information may help resolve problems with the Dell T5810 PC.

The FRUs associated with the Dell T5810 are: the two SSDs, DVD-RW drive, CMOS battery and the PC. See Dell T5810 Lower Level FRU Replacement.

  • danger
  • Electrocution hazard
  • Hazardous voltage is present when the Global Operation Console (GOC) is energized.
  • Before beginning any work, perform LOTO. See the MR Service Safety Manual (5452735).

Dell vendor diagnostics

The Dell T5810 has built-in diagnostics. Press F12 at bootup to run a built-in self test (BIST). For more information, refer to latest revision of the Dell T5810 Owner’s Manual (DOC1754575) available from the online documentation library.

Diagnostic LEDs

The diagnostic LEDs are located on the front of the chassis next to the power button. These diagnostic LEDs are only on during the POST process. They blink when the power button is amber or off, and they do not blink when the power button is white. After the operating system starts to load, they go off.
note: The diagnostic LEDs are only an indicator of the progress through the Power-On Self Test (POST) process. These LEDs do not indicate the problem that caused the POST routine to stop.
Table 1 POST diagnostic LED states
Power LED state System state Notes
Off S5/S4 Normal - The system is Off/Hibernate
Blinking White S3 Normal - The system is in Standby/Suspend
Blinking Amber N/A Abnormal - If the PSU does not start, run the PSU BIST. Replace the PSU.
Steady White S0 Normal - The system is on and operates correctly
Steady Amber N/A Abnormal - The system will not start. Check the motherboard components, or replace the motherboard.
note: The amber LED blinking scheme pattern is 2 or 3 blinks followed by a short pause then as many as 7 blinks follow. Pattern has a long pause inserted in the middle. For example 2,3 = 2 amber blinks, short pause, 3 amber blinks followed by long pause.
Table 2 Amber LED POST diagnostic patterns
Blink pattern System state Notes
2,1 A possible system motherboard failure has occurred. Replace the motherboard.
2,2 A possible PSU or cabling issue has occurred. Run the PSU BIST. Check the PSU cabling to the motherboard to make sure that all cables are installed correctly.
2,3 A possible motherboard, memory, or CPU failure has occurred. If two or more memory modules are installed, remove the modules, and then reinstall one module and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error.
2,4 A possible coin cell failure has occurred.

Replace the CMOS battery.
2,5 The system is in Recovery Mode. BIOS checksum failure was detected and the system is now in recovery mode.
2,6 A possible processor failure has occurred. Re-seat the processor.
2,7 The system finds the memory modules, but a memory power failure has occurred. If two or more memory modules are installed, remove the modules, and then reinstall one module and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error.
3,1 PCI device configuration activity is in progress or PCI device failure was detected. Remove all peripheral cards from the PCI and PCI-E slots and reboot the computer. If the computer boots, add the peripheral cards back one by one until you find the bad one.
3,2 A possible HDD or USB failure has occurred.

Remove all external USB connections to the PC.

Re-seat all power and data cables to HDDs. Reinstall all USB devices and check all cable connections.
3,3 No memory modules are installed.

If two or more memory modules are installed, remove the modules, then reinstall one module and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified all modules without error. If available, install working memory of the same type into your computer.
3,4 Power connector not installed properly. Re-seat the 2x2 power connector from the power supply unit.
3,5 Memory modules are detected, but a memory configuration or compatibility error has occurred. Make sure that no special requirements for memory module or connector placement exist. Make sure that the memory you are using is supported by your computer.
3,6 A possible system board resource and/or hardware failure has occurred. Clear CMOS (re-seat the coin-cell battery).
3,7 Some other failure has occurred.
  • Make sure that the display or monitor is plugged into a discrete graphics card.
  • Make sure that all hard drives and optical-drive cables are properly connected to the system board.
  • If there is an error message on the screen identifying a problem with a device (such as the floppy drive or hard drive), check the device to make sure it is functioning properly.
  • If the operating system is attempting to boot from a device (such as the floppy drive or optical drive), check system setup to make sure the boot sequence is correct for the devices installed on your computer.

Disk drive configuration

There are no jumpers required to configure the disk drives. Make sure that the power cables are connected to the correct SATA connectors on the board. The connectors are labeled on the board as HDD1 and HDD0.

Error messages

The information in this section is taken from the Dell manual for the computer, and can help in troubleshooting issues with the Dell PC.

There are three types of BIOS error messages that are displayed depending on the severity of the issue:

  • Errors That Halt Your Computer Completely: These error messages will halt the computer requiring you to cycle the system's power. The following table lists the error messages.
  • Errors That Do Not Halt Your Computer: These error messages will not halt your computer, but will display a warning message, pause for a few seconds, and then continue to boot. The following table lists the error messages.
  • Errors That Soft Halt Your Computer: These error messages will cause a soft halt of your computer and you will be prompted to press F1 to continue or F2 to enter the system setup.
Table 3 Error messages
Type Error
