Hi,
I'm trying to test WPBT feature. Windows tried to launch application but
its failing to launch it. In the WPBT document it is mentioned that the
status of the operation is set to platform using _PBS method. But, the
method is not called at all. Also, in the help of iasl compiler I observed
the error "_PBS, no matching predefined names" for this method.
Do we need any additional support in ACPI for the method to work?
Thanks in advance.
