Hello,

on a a Lenovo ThinkCenter, I installed Win10, everything is fine, except when I want to shut it down, Win10 closes properly but the fans don't stop, I have to use the power button.

I found nothing in the BIOS to help me, do you have any idea?

Thank you

    Hello,

    What about the Windows power options?

    If there's nothing, perform a "Clear CMOS": Often the manual indicates how to do this.

    1. Disconnect the power supply.

    2. Remove the CR2032 battery.

    3. Check if you have a jumper on pins with CLR_CMOS or CLRTC written next to it.

    If it's there with 3 pins, move it to the other pins X X O > O X X for at least 10 seconds.

    If you don't have it, you can short-circuit the two pins with a screwdriver or other metal object for at least 10 seconds to discharge the capacitors.

    Sometimes short-circuiting the two contacts of the battery holder can do the same thing.

    4. Put the jumper back as it was before, or stop short-circuiting.

    5. Reinsert the battery.

    6. Reconnect the power supply.

    7. Start the PC.

    8. Reconfigure the BIOS.

    Hello

    There are indeed some powerful PCs that allow the fans to continue running after Windows has been closed, to prevent "processor overheating lock-up," but I don't know where to find the settings.

    An AI confirms this in the BIOS or through third-party software:

    • Some computers allow you to configure the behavior of the fans in the BIOS. You can check if your ThinkCentre has an option to keep the fans running after shutdown.
    • Management software: There are third-party software programs that can control fan speed and behavior after the operating system shuts down.

    Conclusion

    Leaving the fans running after closing Windows is a good practice to prevent overheating and extend the life of your hardware.

    Hello

    Thank you for the response, but my fans are still running, I don't see where these settings could be.

    As for the third-party software (if there is any), where could it be located, given that I formatted my drive before installing Windows 10,???

    Best regards
