| Hey, I emerged apmd, read the man, searched the forum and googled, but I can't find what to do. I only want my hard drives to spin down after some idle time, that's it, but I can't seem to find how to configure apmd. |

Actually, if all you want to do is spin down your hard drive, you don't need apmd.
man hdparm will give you some useful help. The -S option is probably the one you want. Note that popular wisdom has it that the power required to spin up a hard disk is roughly equivalent to that required to keep it running constantly for 30 minutes. So try not to let it spin down for periods less than this or you defeat your purpose.
(For suspending the whole machine, apm -s and variants will do that - you don't even need apmd installed for this. apmd is really just to enable you to run arbitary scripts in response to power-saving events like suspend and wake, so that you can restore network connections and things like that.) |

| Ah thanks alot, I don't care much about the power use, it's just the noise that irritates when I'm sleeping. |

| Why don't you enable power management in your BIOS? There should be a setting to spin down drives after a certain amount of inactivity. Provided you built APM into your kernel, it should work fine. My laptop spins down and sleeps perfectly with nothing more than APM built into the kernel. I only emerged apmd because I wanted to get my power info by typing apm at the console, instead of cat /proc/apm. However, apmd is not running. |

| Hm, I have to admit I never encountered that option in my BIOS, I do have a desktop pc, not a laptop, maybe that option only exists with laptops? Anyways, if the hdparm works fine, I'll use that, else I have to reboot. |

I've enabled APM in BIOS, too and build apm into the kernel, but my Notebook (Thinkpad T23) won't suspend automatically.
Anyone knows what can be wrong? Anyway, I can suspend with
so it's not broken at all. |

my laptop has apm enabled in both the bios and the kernel and i have not had any troubles whatsoever getting it to sleep or suspend (well...kde gave me a short fit). thus i have never looked deeply into apm since it always 'just worked'
man apm might hold a few answers for you...
