Thanks Pietro, I really appreciate this. Can I ask by chance, does this
turn on your battery indicator light on your front panel on your MSI
notebook?
Also, what's the downside of changing ASL? Can I brick my notebook? I just
have to ask since I am assuming I will be changing the underlying AML
generated which I suppose can cause chaos (i.e. I want to make sure I can
reset it).
