T480 CPU lag

2020-08-12, 9:08 AM

I have a problem with my Thinkpad. About 2-3 times a day (~ 12h period) the computer slows down. Same time the cooler slows down, so I always know it's happening again. CPU utilization drops to ~11% and won't go up for a minute or two.
I added a screenshot of CPU performance. The first box from left is the slow period, utilization almost constant 11%. The next box is like wake-up, when it is possible to switch tabs in browser etc. (slow, but possible). And the third box is when the cooler speed goes up and computer returns to normal state.

I also checked the Power settings, but everything's seems to be ok, and changing those values won't help.

Maybe someone can help with this.
