Solved upstream with kernel 4.11 RC1 from Ubuntu kernel archive. I'm back to 4.23 W instead of 8.26 W in same power conditions.
I reach PC8 power state (powertop) instead of PC3. Hope the APST Andy's patch (I guess it's the key ?) will be backported soon to Zesty's kernel. ** Tags added: solved-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1664602 Title: Using an NVMe drive causes huge power drain To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1664602/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
