That's not a fix. The problem is the BIOS defaults, not the special case covered by laptop mode, which is *on battery*. If you change laptop mode's defaults, you can just as well disable laptop mode completely: you throw away the baby with the bath water. Laptop mode is intended for use in battery mode ONLY, and in that mode, people generally use their laptops continually. If you then set the drive to spin down after two minutes, you can be quite sure it will almost _never_ spin down. The power you're after is the power gained from spinning the drive down in the period between drive usages, which is in the order of a couple of minutes. So, you want to spin down as soon as possible, to get as much gain as possible. I'd done some math in a comment in bug 59695, which has now sadly been removed by the Launchpad/Ubuntu crowd since they made this bug page a static page. The gist was, as long as you enable laptop mode only on battery, and disable drive power management in all other situations, you run no risk at all: the battery should be replaced _long_ before the hard drive. So it's no use tweaking laptop mode settings -- they're not a problem. -- Hard drive spindown should be configurable https://bugs.launchpad.net/bugs/17216 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
