A tentative success story: Using the patched r8169 driver & powertop tunables set to "GOOD", my CPU was able to reach the C7 package state. I noticed C7 is only reached when the laptop is unplugged, otherwise only C3 is reached. I am not sure if this behavior is expected, but may be leading to the confusion above.
CPU temperatures seem to idle around 40-60 degrees celsius. This is slightly higher than Windows 10 (where I checked it at about 40-50 degrees celsius). The fan kicks on every once in a while, but goes away as expected ~30 seconds later. I am using Ubuntu 17.10 with the 4.13.0-16-generic kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1602888 Title: Dell Inspiron 7559 fans do not shut off once started, even when cool To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1602888/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
