    I'm curious if they fixed the TOLUD yet. Can you run this command in Powershell on your computer?

    Then reply to this thread with the output under PCI bus? Should be the last section.

    The modified fan rules looks interesting although there's no potential to limit the maximum fan speed which is needed to shift the heat from a fully loaded CPU (I have seen slightly throttling when a CPU core reaches 95C).

    I'll refrain from applying the BIOS update until I'm next home in case something goes wrong.

    I'll take this opportunity to add that an updated Intel graphics driver has also been posted on the T420s downloads.
