Hi to all, I have a big question for you:
Sony provides an utility (that of course runs only on win) that lets you set the maximum charge of the battery to 80% or even 50% (in order to avoid battery decay, they say). This program probably activates some hw switch in order to do this because the battery doesn't change over that threshold even if the laptop is switched off or if I'm running linux (these guys from Sony are very dedicated)!
Does anyone know a sw on linux that lets me change this threshold?
This laptop is a good one but it's designed only for windows, EFI (Insyde H2O) looks for win boot manager, proprietary sw for changing hw switches etc.....

I think you can only set one of 50%, 80%, or 100%.
echo 1 | sudo tee /sys/devices/platform/sony-laptop/battery_care_limiter #for 80%
echo 2 | sudo tee /sys/devices/platform/sony-laptop/battery_care_limiter #for 50%
echo 0 | sudo tee /sys/devices/platform/sony-laptop/battery_care_limiter #for 100%
