Battery and heat problems with the latest kernel

view story

http://forums.fedoraforum.org – I'm using a Dell Vostro V131 with Fedora 17 and kernel 3.6.1-1 (64-bit). The laptop has been working perfectly up until this. After the latest kernel upgrade the laptop battery lasts for only about an hour even with 100%, the machine gets very hot and it constantly sounds like a jet plane taking off. :C Is there anything I can do about this? Downgrade kernel? Pray to Tux and do some magick? Seriously though, any help is appreciated - my employer's server room is quieter than my laptop. (HowTos)
