Gnome shell extension -- shows battery power consumption of ThinkPad laptops

TP Wattmeter

Forked from https://bitbucket.org/blackBriar/wattmeter and https://github.com/luispabon/gnome-shell-battery-time-and-percentage

Simple extension to show current power consumption in Gnome battery widget.

Differs from original wattmeter -- it reads directly from /sys/class/power_supply/BAT0/power_now.

Tested with ThinkPad Carbon X1 Gen4

Download from: https://extensions.gnome.org/extension/2308/tp_wattmeter/

tp_wattmeter's Issues

Gnome 43 support: aggregateMenu is gone, replaced with quickSettings

The extension is incompatible with gnome shell v43

https://gjs.guide/extensions/upgrading/gnome-shell-43.html#quick-settings

I am trying to work out how to fix it.

Discussion for new feature: show when lap mode is activated

Hi, modern thinkpads enter 'lap mode' when movement of the device is discussed. After a period of no movement, lap mode is deactived. This seems to take about five minutes at the fastest. Lap mode can be triggered with even slight movement, such as moving the laptop while it is on the desk.

When lap mode is activated, thermal throttling is quite severe. I have tested it on a Tigerlake X1 and Yoga; throttling caps CPU temp at 65 C, but in performance mode it should be 95C.

Gnome power settings will show when lap mode is activated, but it is annoying to check.
It's a good for an extension with an indicator, such as tp_wattmeter. It is not related to power consumption, but it is related to ThinkPads.

Would a pull request for this be accepted? Otherwise I will work on a stand-alone extension. I propose to use capital letter L to indicate when lap mode is detected, and nothing if not detected.

Detection of lap mode is done by inspecting /sys/devices/platform/thinkpad_acpi/dytc_lapmode
which has a value of 1 or 0. The polling period of the existing extension will be fine.

Gnome 42 support

Can we hope that this extension would be updated to run on latest LTS of Ubuntu (and upcoming Fedora release)?

Display correct results with multiple batteries

Some Thinkpads (up to T480) have two batteries. E.g. in my T450 the internal battery is BAT0 and the external/replaceable is BAT1. The system always discharges the external first (and while doing so, the power reported by the internal BAT0 will be 0).

One easy way to go around this is taking the maximum power of BAT1 and BAT0 and displaying that. (Or the sum of the two, just in case. )

Gnome 41

Doesnt work on gnome 41

Broken battery percentage and dual battery support (if possible)

Also, would there be a way to monitor power consumption of both of the batteries for dual battery systems like the T560?

Only display when running on battery

It would be nice if you could add an option to hide the display when the laptop is not running from battery but from AC. The "0.0W" displayed when running from AC is not too informative, it just adds noise/cruft to the status bar.

Gnome 40.0.0

Hey, your extension is fantastic... but sadly doesn't work on Gnome 40.0.0

Precision of percentage is excessively high

I love the concept of this extension, but in practice it makes the display of my battery percentage take up way too much space because the decimal precision is way too high. One or two decimal points really ought to be enough.

I'm using a t450s with Fedora 32, gnome-shell version 3.36.5-1.fc32. Possibly worth noting it has two batteries.
