I've seen hints at some kernel power bug affecting battery life if updating to 11.10 -- as for example here.
I relation to this, I have three questions:
- How can I tell if my machine is affected after having updated?
- What can I do to fix the problem?
- Will these solutions have a negative effect if I'm not affected by the problem?
For example, will the proposed workaround from the link above have any negative consequences?
