And there are others in the same StackExchange thread sharing their own experiences with the problem and the fix.

Again moving power back to the right side, restoring State B, resolves the problem immediately.Īmazingly, this is actually a thing that happens. Moving power back to the left side, restoring State A, quickly restores the temperatures and kernel_task again comes back after 3-4 minutes. The left side temperature drops and the kernel_task goes away within about 15 seconds. State B cures the kernel_task problem by moving power from the left ports to the right. About 3-4 minutes later the dreaded kernel_task high CPU usage starts. You can see the Thunderbolt Left Proximity temperature sensor rise quickly.

State A a USB-C hub (a mouse and keyboard, plus power) and a USB-C HDMI 2.0 adapter, both on the left side. It's game over at that point with fans spinning up and CPU usage skyrocketing. Charging may be faster or slower than via the regular T470 power-adapter. So warm that the Thunderbolt Left Proximity sensor sees the increase in temperature and the kernal_task process appears. The T470 can be charged via USB-C (Lenovo even sells such chargers as accessories for the T470), so if your MacBook Pro charger is a USB-C charger it should work. When you're charging using the left-hand ports and have other accessories plugged into the same side, things get a bit too warm. I'm not going to get into all the nitty-gritty of what's going on – you can read Adam's post for that – but the tl dr is pretty simple. But I know you're asking the obvious question – what's this got to do with charging? It's a good question and one that was answered emphatically in the same thread.
