Is it? I was under the impression that you were discussing power
management in context of your Sony laptop?
autopm behavior
Acceptable behavior values are described as follows:
default The behavior of the system depends upon its
model. Desktop models that fall under the United
States Environmental Protection Agency's Energy
Star Memorandum of Understanding #3 have
automatic device Power Management enabled, and
all others do not. See the Notes section of this
manual page for more information.
If you read the Notes section, I think it will be clear to you that it
is not presently enabled by default in the case of your laptop.

Perhaps. Sarito or Randy (cc'd) might be able to explain it more clearly
and then you can decide if you'd like to file an RFE.
