Bug ID: 1046957
Summary: Laptop power consumption increased after kernel update
Classification: openSUSE
Product: openSUSE Distribution
Version: Leap 42.2
Hardware: Other
OS: Other
Status: NEW
Severity: Normal
Priority: P5 - None
Component: Kernel
Assignee: kernel-maintainers@xxxxxxxxxxxxxxxxxxxxxx

Blocker: ---

After kernel update openSUSE-2017-734 (kernel 4.4.73-18.17-default), my laptop
drains battery too fast even when idle (power consumption is ~19W according to
powertop).
Booting an older kernel 4.4.70-18.9-default fixes the situation (power
consumption while idle is ~9W).

The laptop is ASUS U30SD. It has nvidia GPU onboard, so this it's possible that
GPU does not turn off when idle, at least power consumption numbers are
similar.
