Source: linux Version: 4.5.0-2 Severity: normal Dear Maintainer,
Since the dist-upgrade this weekend, I noticed massively increased power consuption on my T460p. I measure this by battery lifetime and the wattage reported by ACPI. The wattage has increased from the range of 7W -- 10W with my usage pattern to 10W -- 12W. These increased metrics are not due to a change in measurement. The battery life has reduced alongside. I have tested with 4.5.0-1 and the problem does not occur there. I was unable to find a possible cause using powertop. What I noticed is that the fan runs even though it would normally not under the load I am putting on the machine. I cannot tell whether this is the cause of the problem, or whether the fan merely runs because something else is putting load on some system component which needs cooling. Please let me know whether there is anything I can do to provide more meaningful data. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.5.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
