Support for Lenovo Thinkpad T490s
Hi,
Thanks for this very useful fix! Too sad Lenovo doesn't get this implemented in an OS-independent way.
I tried running it on a T490s today, with no noticeable success. Power limit stays at 25W for a few seconds and then drops to 15W, where it stays with a CPU temp of 70°C.
On Windows, the TDP limit is 51W first and then stays at 25W.
Here's the debug output:

Do you think the T490s can be supported?
Best regards Robert
I guess they are limiting the TDP to 15W in a new way on the T490 series. Maybe setting the correct UUID (#70) could help
Hi,
Setting the profile seems to help, but only when it's done directly at boot, before any CPU stressing has been performed. I put it into /etc/rc.local for that reason and now TDP always is 28W, no short term limit seems to be applied, even though I configured 51W for 29s via throttled.
I'm fine with the behaviour for now, 28W permanent is enough for thermal throttling to kick in after a few seconds, but it would be nice to have the 51W short term limit as on Windows.
BTW, they really did a bad job with the terrible cooling on T490s, the i7-8565U undervolted at -110mV stabilizes at only 4 x 2.6-2.7 GHz at 95°C after ten minutes, meaning the cooling can only handle 18W permanently.

I have the same TDP issues with my T490. What do you mean by "Setting the profile" in /etc/rc.local, could you please explain this to me?
Danke
edit: Found it echo 63BE270F-1C11-48FD-A6F7-3AF253FF3E2D | tee /sys/devices/platform/INT3400:00/uuids/current_uuid. But after a reboot cat /sys/devices/platform/INT3400:00/uuids/current_uuid always return INVALID. There are even more people with this problem, see here https://www.notebookchat.com/index.php?topic=97614.msg362974#msg362974 (german).
I also had throttling issues on my T490 (should be similar enough processor to the T490s). In addition to using the throttled daemon, I had to disable secure boot through BIOS for the throttling issue to go away. Thought this may be a point some might find useful.
@PHillner What BIOS version do you have installed? I am running N2IET74W (1.52) with "Secure Boot"="Disabled", "Platform Mode"="User Mode" and "Secure Boot Mode"="Standard Mode".
I get 100% CPU usage, but only ~11W Power usage at below 60°C.
@HarryWindsor Sorry for the late reply. I have N2IET76W (1.54) at this moment, which seems to be a different version than I had when I previously commented, as v1.54 was released 30 September 2019. This makes me think I had v1.52 back then. At this moment, I am getting 3.5-4 W idle power usage with ~50 C temperature.
