It might yes :)

OK, I guess it is easier if I just order one of those machines here and
figure out how to get the PMIC driver working.

Is the model Asus E200HA? Something like this (sorry the information is
in Finnish but the machine should look the same):

Also can you remind me what exactly is not working so we can prioritize?

Thanks.
