hard disk spin-downs and sleep modes are really needed (to work properly). The problem is with services and even the kernel waking up the hd for silly things. There are things one can do to avoid them, but these should come by default with your distro. Sensible defaults for laptops. It should be easy enough for the system to detect it's running on a laptop (cpu family or whatever) and select an appropriate profile. User intervention is generally not the best way to go on these things (maybe hints, if you want to force a mode or something)
And as far as I know, GPU power profiles are missing as well. (driver dependent?) PS: mind you, there is little difference between windows and ubuntu in my laptop (dell d800). Though, it's been a while since I last tested it with windows (3-4 years ago?), and my memory might not serve me well... -- Bad battery runtime in Ubuntu https://bugs.launchpad.net/bugs/195768 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
