Quoted from Lenovo's feedback: " Due to "DPTF" function will act on Windows system by BIOS/Driver support, the system will turn to cool mode when keep high temperature several minutes. But Linux system didn't have driver support DPTF function, it only have TDP limit on platform. So user should have different between Windows and Linux system as normal behavior. "
And my test result: 1, When stress testing on Win10, CPU temperature reaches 98C and 3.2G. But this status can't keep more than several mins, it is too hot for CPU. So the CPU tried to maintain a 1.1G freq to cool itself. Then the temperature and freq will go into a loop like 98C/3.2G -> 80C/1.1G -> 98C/3.2G. 2, On Ubuntu 16.04 CPU keeps 80C/2.7G when stressing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1763144 Title: Significantly lower power and thermal limits on ThinkPad T480s (and probably others) than on Windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763144/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
