Try it and choose if use it or not.
The thing is, I am familiar the intent of the package, and familiar with its value. The referenced page - and the rest of my research into this setting - does not provide enough information for me to determine whether I should activate it or not. My thinking is this (and bear in mind that one of my professional roles is security consultant, so I tend to bring a reasonable paranoia, er, doubt, to my thinking): Laptops can be easily detected using dmidecode (for the most part); There are distinct advantages to laptop mode (quieter operation, longer battery life); There are no - or appear not be any - well-documented reasons NOT to use this mode (in fact, I can find no reasons at all!); Therefore, why isn't it enabled by default when a laptop boots? My (doubting/paranoid) self responds "Well, there must be a reason! It would not be turned off unless someone knew SOMETHING, surely!" It's the reason I am trying to determine. You write that the advantages are slim. I disagree, based on my use of my machine. But I cannot get good documentation about the risks or drawbacks of this mode of operation. It is paranoia, performance, or puzzlement (no one knows enough to enable it, so it remains disabled? I feel that bug report coming on strong.... All assistance welcome, pww
