I have a ThinkPad T460p that keeps restarting instead of shutting down. The culprit is the LAN: if it is disabled in the BIOS, the problem is solved. I have already replaced the LAN chip (WGI219LM) twice, done CleanME, flashed another BIOS. Unfortunately all without success. What else can I check?

Check the voltage to ground of LANWAKE#. Confirm the pull-up resistor @ R243 is present and is ~4k7 ohms. Confirm there is a 3v3 (VCC3M) on pin 2 of this resistor.
If LANWAKE# = 0 volts, then the logic board will 'wake up' since this is an active low signal which is denoted by the '#' suffix in the netname. -
the resistance of RL5118 (pull-up resistor of LAN_WAKE#) is 3,7 kOhm (measured in place). VCC3M is present and LAN_WAKE# never drops to 0.
In BIOS the option WAKE by LAN is disabled.Comment

Confirm the same setting within Windows.

The measurement of the LAN_WAKE# signal was taken in Windows. During the whole shutdown and during the following startup the Signal was always 3,3V.
I do not want to use the wake on LAN feature. It is disabled in BIOS intentionally.Comment

I changed the GbE chip and now everything works as expected.Comment

So the WGI219LM LAN controller was replaced for a 3rd time and now it is working? Did you source the part from a different vendor this time? Perhaps the previous ones were fakes?Comment

Hi,
I’ve got a stubborn patient here. The laptop powers on and works, all components like the screen, keyboard, touchpad, etc. are functional. The issue is that it heats up very quickly under load (within a few minutes up to 95°C) and then shuts down shortly after. Subsequent attempts to turn it back on right after a “hot shutdown” result in it shutting off within a few seconds. Interestingly, if I enter the BIOS, it can stay there for 2 days without shutting down (most likely due to low CPU load and low temperatures).
The cooling system has been cleaned, thermal...09-03-2025, 09:32 AM
