It looks like you've done a thorough job troubleshooting so far. The fact that the DHCP server allocates an IP address only after shutting down the server is interesting. Here are a few additional suggestions:

>> Check if your Microserver supports network boot (PXE). If it does, attempt to boot from the network to see if there's any response or if the server is recognized on the network.

>> If your Microserver has Integrated Lights-Out (iLO) or a similar remote management feature, try accessing it to see if you can get any information about the server's status or logs remotely.

>> Some motherboards have a BIOS recovery mode that allows you to flash the BIOS even without a functional display. Check the motherboard's manual to see if your Microserver has this feature.

>> Even if the CPU is soldered, check for any bent pins on the motherboard or any anomalies in the CPU socket.

>> Ensure all connections, including power connectors, are securely in place. Sometimes a loose connection may lead to such issues.

>> Some motherboards have a debug header that allows you to connect a USB debug adapter for troubleshooting. This might give you additional information about what's going wrong.

Given the extensive troubleshooting you've already done, it might be a complex issue that requires more specialized attention. If the server is still under warranty, contacting HPE support would be a good step. If not, a professional technician might be the best option to further diagnose and fix the problem.

Hope this helps!

Update: I bought a PCIe Graphic Card and tried it in N54L,surprisingly it worked.

So the conclusion is that the onboard GPU or onboard VGA connector is dead? Is there anything I can do to fix this?

With external GPU, I was able to install Open Media Vault, and use there server without monitor from now on.

It's great that you were able to identify the issue by testing with a PCIe graphics card, and it's a positive outcome that you can now use the server with an external GPU.

If the onboard GPU or VGA connector is not functioning even after trying different troubleshooting steps, there is likely a hardware issue with that specific component. Unfortunately, in the case of onboard graphics failure, there are often limited user-serviceable options for repair. The GPU is typically integrated into the motherboard, and if it's malfunctioning, it may require professional repair or motherboard replacement.

Here are a few additional things you can try, though they might not guarantee a fix:

>> Check if there's a BIOS/UEFI update available for your Microserver. Sometimes, a firmware update can address certain hardware issues. However, proceed with caution, as a failed update could potentially render the motherboard unusable.

>> Try resetting the BIOS/UEFI settings to default. Sometimes, incorrect settings can cause display-related issues.

>> If the server is still under warranty, consider reaching out to the HPE support.

Since you've successfully installed an external GPU and can use the server without a monitor, you have a functional workaround. While the onboard GPU issue may remain unresolved, you can continue using the server with the external graphics card. If the server is out of warranty, the cost and effort of repairing the onboard GPU may outweigh the benefits, especially if the external GPU meets your needs.

Remember to keep regular backups of your important data, and if the server is part of a critical infrastructure, having a backup plan or redundant systems in place is always a good practice.

Good luck
