The HP EliteDesk series is a popular line of business desktops known for reliability and performance.
However, when there is a hardware issue, the system may fail to boot and emit a series of beeps to indicate the problem. These beep codes are generated by the BIOS (Basic Input/Output System) during the Power-On Self-Test (POST) process.
This guide explains common HP EliteDesk beep codes, their meanings, and how to fix the underlying issues.

| 4 Short Beeps | Power failure | Check power supply and connections |
| 5 Short Beeps | Motherboard failure | Replace motherboard |
| 6 Short Beeps | CPU failure | Reseat or replace CPU |
| 7 Short Beeps | GPU (Graphics Card) failure | Reseat or replace GPU |
| 8 Short Beeps | CMOS battery failure | Replace CMOS battery |
| No Beeps | Possible PSU, CPU, or motherboard issue | Check power connections, PSU, and motherboard |
Common HP EliteDesk Beep Issues and How to Fix Them
2 Beeps – BIOS Corruption
Possible Causes:
- BIOS update failed or is corrupted
How to Fix:
- Reset the BIOS by removing the CMOS battery for a few minutes
- Try booting with a BIOS recovery USB drive
- If the issue persists, reflash the BIOS using HP’s official tools
3 Beeps – RAM (Memory) Issue
Possible Causes:
- Faulty or improperly seated RAM
- Incompatible RAM modules
How to Fix:
- Turn off the PC and unplug it
- Remove and reseat the RAM sticks
- Test the system with one RAM module at a time
- If RAM is faulty, replace it with compatible modules
4 Beeps – Power Supply Failure
Possible Causes:
- Insufficient or faulty power supply
- Loose power cable connections
How to Fix:
- Check the power cord and internal PSU cables
- Test with a different power outlet or power adapter
- If the issue persists, replace the power supply unit (PSU)
5 Beeps – Motherboard Failure
Possible Causes:
- Hardware damage on the motherboard
- Corrupt BIOS preventing startup
How to Fix:
- Check for burnt components or physical damage
- Reset the BIOS by removing the CMOS battery
- If the issue persists, the motherboard may need replacement
6 Beeps – CPU Failure
Possible Causes:
- CPU not installed correctly
- Overheating or thermal paste issue
How to Fix:
- Turn off the PC and unplug it
- Remove the CPU and check for bent pins
- Reapply thermal paste and reinstall the CPU cooler
- Ensure the CPU fan is spinning properly
7 Beeps – GPU (Graphics Card) Failure
Possible Causes:
- Graphics card not properly seated
- GPU overheating or damaged
How to Fix:
- Turn off the PC and unplug it
- Remove the graphics card and reseat it in the PCIe slot
- Ensure the GPU power connectors are properly attached
- If using integrated graphics, try an external monitor or replace the GPU
8 Beeps – CMOS Battery Failure
Possible Causes:
- CMOS battery is dead or missing
How to Fix:
- Turn off the PC and remove the old CMOS battery
- Replace it with a new CR2032 battery
- Restart the system and reset the BIOS settings
No Beeps – Power Supply or Motherboard Issue
Possible Causes:
- Dead power supply, motherboard, or CPU
How to Fix:
- Check if the power cable is plugged in properly
- Test the power supply with another PC or use a different PSU
- Inspect the motherboard for damage (burnt components, loose connections)
How to Prevent HP EliteDesk Beep Code Errors
- Keep your PC clean to prevent dust buildup and overheating
- Regularly check hardware connections (RAM, GPU, CPU, power cables)
- Use a high-quality surge protector to prevent power fluctuations
- Update BIOS firmware carefully to prevent corruption
