If you’re facing issues with your Elitedesk Mini 800 G5 after replacing the motherboard, you’re not alone. It’s frustrating when things don’t work as expected, especially when you’ve invested time and effort in repairs. Let’s dive into how to troubleshoot the 3-4 fault code issue you’re experiencing.
Start by ensuring you have a compatible power supply. The 3-4 fault code typically indicates a power issue, so it’s vital to use the correct power supply. For the Elitedesk Mini 800 G5, the part number you should look for is L06061-001. Always double-check that you’re buying an original part, as third-party supplies can sometimes lead to compatibility issues.
Next, even if you’ve already reset the BIOS, try it one more time. Here’s a quick guide on how to do this:
1. Disconnect the power supply.
2. Remove the CMOS battery from the motherboard.
3. Wait for about 5–10 minutes.
4. Reinsert the CMOS battery securely.
5. Reconnect the power supply and power on the unit.
Make sure your CPU is seated properly and is indeed compatible with the motherboard. Sometimes, a slightly bent pin can cause issues. Try reseating the CPU and ensuring all connections are tight.
If you’re still encountering problems after trying these steps, it may help to test with another known working power supply to confirm whether yours is the issue.
If everything checks out but the problem persists, further investigation might be needed on the motherboard itself. Look for any signs of damage or faulty components.
By following these troubleshooting steps, you should be able to resolve the 3-4 fault code issue and get your Elitedesk Mini 800 G5 running again. Don’t hesitate to reach out for more advice if needed. Good luck!
