Could you verify this by cat /sys/firmware/acpi/platform_profile If it shows "performance", please try switching to "balanced" echo balanced | sudo tee /sys/firmware/acpi/platform_profile You may also switch those modes from the top-right corner menu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2144508 Title: Dell G15 5520: Fan stuck at maximum speed (~4800 RPM) after upgrade to kernel 6.17.0-19-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-6.17/+bug/2144508/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
