    Hi guys,

    My X220 is refusing to boot. When I press the power button, I get the thinkpad logo, and immediately get "Thermal Sensing Error" and then it shuts off.

    Of note, I set 'tpfancontrol' to manual mode and set the fan to 'off'. Did that have something to do with this? When I changed that setting, the computer remained on and was working fine. But once I turned the notebook off, it simply will not turn back on again.

    What do I do? I'm freaking out. It's not even letting me go into BIOS... is there a way I can bypass the message or hack the bios or do something?

    Please help. Thanks!

    Usually that means the fan isn't working. Have you cleaned the fan?

    With air blower, yes. And when the computer boots for a few seconds that it does... the fan does operate it seems.

    Any thoughts?

    Just wanted to update: I fixed the issue thankfully. All it took was taking apart the laptop, unplugging the fan from motherboard and re-plugging it back in.

    So stressful yet so simple.
