I would still like to confirm that the patches from the new thread (patch1 patch2 patch3) were also passed along to engineering. The old thread (prior to merging with this new thread) is the one that received a response from Lenovo, however the old thread contained no useful information about the solution.

The thread title should also be updated, because currently it conceals the importance of the issue.

 

At present, it should be: "ACPI bug - affects X1C6, X1Y3, X280, T480s, T480, T580, P52s, possibly more."

Where/how do you see the high CPU usage? Which process? When idle, my T480 is only about 4% CPU and around 50°C, but when I work on Windows, it feels sluggish and the CPU temp goes up to 98°C (the latter most likely is another issue).

I would also like to request a status update.

 

The T480s UEFI changelog shows a gap of 11 days between the releases of v1.10 and v1.11. It has now been the same length of time since the patches in this thread were posted, and they would take significantly less effort to apply and test than the changes made in v1.11.

I also have this issue, it appears that disabling TB3 has resolved it.  There goes my thunderbolt 3. 

 

I opened a ticket with lenovo.

 

I'll reference this thread.

Thanks, every attempt to draw Lenovo's attention is one step closer to fixing the issue.

 

If you need thunderbolt in the meantime, you can restart the computer after each cold-boot (power-on) or wake event (suspend/hibernate). It's a nuisance, but at the moment, it's the only way to use thunderbolt without triggering the bug.
