HIgh power concumption on network interface
by kingma＠bluewin.ch
I observe a sustained high power consumption of 5- 10 W on the ehternet adaptor e1000e on a lenovo thinkgpad t430s. Such I high power drain cannot be correct can it? the total power consumption is around 25 W which is a concern for battery life.

PowerTOP V2.11 Release
by Kammela, Gayatri
We are pleased to announce the release of PowerTOP v2.11.
About PowerTOP:
PowerTOP is a Linux tool to diagnose issues with power consumption and power management. In addition to being a diagnostic tool, PowerTOP also has an interactive mode you can use to experiment with various power management settings, for cases where the Linux distribution has not enabled those settings.
PowerTOP reports which components in the system are most likely to able for higher-than-needed power consumption, ranging from software applications to active components in the system. Detailed screens are available for CPU C and P states, device activity, and software activity. For many years, PowerTOP has been used heavily by Intel, Linux distributors, and various parts of the open source community.
About PowerTOP v2.11 release:
This release has an important feature to support runtime pm enabling for AHCI. A few bug fixes focusing to support PowerTop to run in newer platforms. We have also enabled support for Intel's Ice Lake server and Ice Lake client with new Sunny Cove microarchitecture, Tiger Lake mobile and Tiger Lake desktop, and atom based Tremont (Elkhart Lake). There has also been some bug fixes thanks to the contributors from the open source community.
Thank you to everyone who contributed to this release!

[PATCH] Make the wakeup toggle text clearer.
by Zane Zakraisek
The text is currenly "Enable" or "Disable", which makes it seem like
toggling is needed to get it in that state.
Instead the text should be "Enabled" or "Disabled" which reflects the
current state.

A discharge rate of 229 mW is not likely.
The other problem though is that upower is all over the map, it varies
between 1 hour and 5 hours remaining. So I wonder if they're both
getting spurious data from the battery or from the kernel (not sure
how it works) and are just handling bad data differently?
Thanks,
