Understanding the Issue:

A solid white power button on a Dell Precision T5820, accompanied by no display, typically indicates a hardware-related problem. Here are some potential causes and troubleshooting steps:

Common Issues and Solutions:

  1. Monitor and Cables:

    • Ensure the monitor is powered on and the cables are securely connected.
    • Try a different monitor or cable to isolate the issue.
    • Check for bent pins in the video connectors.

  2. Graphics Card:

    • If you have a dedicated graphics card, ensure it’s securely seated.
    • Try reseating the graphics card or using the integrated graphics (if available).
    • Check for any damaged pins on the graphics card.

  3. Video Output:

    • Ensure you’re using the correct video output port on the graphics card.
    • Try different video output ports (DisplayPort, HDMI, DVI, etc.).

  4. BIOS Settings:

    • Enter the BIOS (usually by pressing F2 or Del during boot) and check the video output settings.
    • Ensure the integrated graphics or dedicated graphics card is enabled.

  5. RAM:

    • Reseat the RAM modules to ensure proper contact.
    • Try booting with one RAM stick at a time to isolate faulty sticks.

  6. Overheating:

    • Check for excessive dust buildup in the system.
    • Ensure the CPU and GPU fans are working correctly.

  7. Power Supply:

    • Verify that the power supply is functioning correctly.
    • If possible, try a different power supply.

  8. CMOS Battery:

    • Remove the CMOS battery (located on the motherboard) for a few minutes, then reinsert it. This will reset BIOS settings to default.

Additional Tips:

  • Check for Error Codes: Listen for any beeps or look for error messages on the screen during startup.
  • External Display: Try connecting to an external display to rule out monitor issues.

If the Issue Persists:

  • Dell Support: Contact Dell technical support for further assistance.
  • Professional Repair: Consider taking the system to a qualified technician for diagnosis and repair.

By systematically checking these potential causes, you should be able to identify and resolve the no display issue on your Dell Precision T5820.
