I created an ASL file and located what appeared to be the code block where that value was set. I followed the statements and nothing appeared to be unusual. (Of course, I might have missed something because I don't have much experience with ACPI programming.) One thing I did notice, however, is when I compiled that file and got two errors arising from: Store (Local0, Local0) where Local0 hadn't been defined in that part of the code. I have no idea how that came about, but it successfully compiled after I commented out that statement. (A bug in the original code, perhaps?) > > best of luck and when you get a working modified AML keep > it somewhere for when you reinstall... Agreed.
