| Thanks Pietro, I really appreciate this. Can I ask by chance, does this

| notebook?
This was working anyway, IIRC.

| Also, what's the downside of changing ASL? Can I brick my notebook?
I just

| generated which I suppose can cause chaos (i.e. I want to make sure I can
| reset it).
No, it just changes the ACPI code used by the operating system. It
doesn't modify anything in your laptop. If it doesn't work, just disable
it and reboot :)
