The "Top" port may be more sensitive to cable quality than the "Bottom" port. Use a known working Ethernet cable (e.g., the one from your bottom port or a console).
If the hardware is fine but the system reports an error:
How to Fix System Error RG45 Top System Error RG45 Top is a frustrating technical glitch that typically appears on high-end gaming laptops and customized desktop rigs. It usually points to a communication failure between the system firmware and the integrated power management controller. When this error triggers, users often experience sudden shutdowns, thermal throttling, or a complete failure to boot into the operating system.
Understanding the root cause is the first step toward a solution. This error code is frequently linked to outdated BIOS versions, corrupted power distribution drivers, or physical overheating in the voltage regulator modules. Fortunately, most users can resolve this issue without needing to send their hardware in for professional repair.
The most effective starting point is a hard power reset. Shut down your machine and disconnect the power cable. If you are using a laptop with a removable battery, take it out. Hold the power button down for thirty seconds to drain the capacitors. Reconnect the power and attempt a boot. This simple step often clears the temporary instruction cache that causes the RG45 Top flag to trigger.
If the hard reset fails, your next move should be a BIOS or UEFI update. Manufacturers release firmware patches specifically to address power management errors like RG45 Top. Visit the official support page for your motherboard or laptop model. Download the latest firmware onto a formatted USB drive and use the built-in flash utility in your BIOS menu to update the system. Ensure your device is plugged into a stable power source during this process, as a power loss during a BIOS flash can permanently damage your hardware.
Driver conflicts are another common culprit. Specifically, the Advanced Configuration and Power Interface drivers can become corrupted after a major Windows update. Open the Device Manager, navigate to the System Devices section, and look for entries related to the Power Controller or ACPI. Right-click these entries and select Uninstall Device, then restart your computer. Windows will automatically reinstall the clean versions of these drivers upon reboot, which often solves the communication loop causing the error.
Thermal management should not be overlooked. The "Top" designation in the RG45 error code often refers to the upper threshold of the VRM temperatures. If your cooling fans are clogged with dust or the thermal paste on your heat sinks has dried out, the system will throw this error to prevent hardware melting. Use a can of compressed air to clear out all vents and fans. If you are comfortable opening your device, consider reapplying a high-quality thermal compound to the processor and GPU.
Finally, check your peripheral connections. In rare cases, a faulty USB device or a shorted keyboard backlight can draw irregular voltage, triggering a system-wide RG45 Top error. Disconnect all external devices except for your mouse and monitor, then add them back one by one to see if a specific piece of hardware is the catalyst for the crash. By following these systematic steps, you can stabilize your system and return to your normal workflow.
It is highly likely you are encountering one of the following two issues:

A corrupted registry entry or damaged installation file is a prime suspect.
