Q: Is there a way to stop the blinking white LED?

You can disable led indication for battery full via executing (root not required):

mcetool --disable-led-pattern=PatternBatteryFull

To undo, execute:

mcetool --enable-led-pattern=PatternBatteryFull

The tool can be installed via (root required):

devel-su
pkcon refresh
pkcon install mce-tools

Another alternative is to override default led patterns via installing custom mce config files. The default values and short explanation about format can be found from /etc/mce/20hybris-led.ini.

Note: There is no need to edit existing files. Creating a new file - with higher two digit number in front - can be used to override values defined in already existing files. That is both easier to undo and your modifications will not be lost on the next upgrade.

For example: (without affecting other uses for led) when battery gets full, led blinks red for one minute (root required)

printf "[LEDPatternHybris]\nPatternBatteryFull=40;4;60;500;2500;ff0000\n" > /etc/mce/90-battery-full-hack.ini
systemctl restart mce

And to undo:

rm /etc/mce/90-battery-full-hack.ini
systemctl restart mce
