Intel XTU Power limit throttling bug

V 6.5.2.4

There is a bug where XTU does not power limit to the required wattage when my laptop wakes up from sleep. I have to set the wattage again for the power limit to happen

What is your processor model number?  If not an X or K processor, XTU does not support your processor.

Also, if you are attempting to undervolt your laptop, that has been disabled due to a security threat:

You have a U processor, which is not supported by XTU.

From the XTU download page:

"Intel XTU may or may not work on unsupported processors."
