I am running Debian Buster (testing) / Sid on an Iball Excelance laptop (an Indian company). I initially had problems with the laptop trying to suspend and then freezing immediately after finishing booting up. These problems went away when I included the
acpi=strict parameter in boot-time kernel options.
However, the problem now is that there seems to be no way to get information about the battery level. The usual
/sys/class/power_supply is empty and
/proc/acpi only has a
button directory in it and a file called
Is there any way around this? Can I try some other acpi parameter at boot up (
acpi=off won't help and in any case blocks the
i915 graphics driver,
acpi=noirq did not stop the freezing problem)? Or is there some other way to find out the battery level?
