maybe I'm wrong in what I'm saying...
device AC could have _PSR but not _STA.
when _STA exists it gives us this information:
0xf -> AC adapter exists
0x0 -> AC adapter does not exists
because this information it is not used later, I really do not
understand why _STA it is evaluated.
some hints?
tnx
