I was having thermal issues in Linux all the time before I updated the BIOS:
You can only update the bios with Windows. https://support.lenovo.com/gb/en/downloads/ds541233 I used a Windows tool called Rufus to make a bootable windows USB drive. (Tried a number of linux tools to do this but didn't have any luck) I also needed a fast enough USB drive to do this: Samsung BAR Plus USB 3.1 Flash Drive 128GB - 300MB/s (MUF-128BE3/AM) - Champagne Silver Flashed my bios from the Windows USB drive successfully. After the bios update only had issues when the laptop is charging. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873083 Title: Lenovo Yoga C940 frequently does thermal shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1873083/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
