what do you mean by non-working power button?
Pressing the power button doesn't power off the laptop, right?
what if you press it for four seconds?

please run "grep . /sys/firmware/acpi/interrupts/*" both before and
after pressing the power button and attach the result.

what did you get?
empty /sys/class/backlight/ entry with any of these drivers loaded?
or the backlight I/F exists but they don't work for you?
