|
|
I got a dell notebook and was wondering if its possible to kick it into sleep, I use it at school and it would kill the battery to either leave it on or powercycle it every time i needed it, so is there any way to get it to go into a powersaving state? |

If you have acpi compiled into your kernel you can put the computer into a light sleep with echo 1 > /proc/acpi/sleep
I have a Dell laptop and it works just fine for me

lol thanks, i knew about that but was wondering if it was possible to get it any deeper sleep, in windows the machine like turns off, from what i can tell the light sleep only kills the display and the processor (and mabye the hd, but laptop hd's are so quiet anyway who knows ) |

I have APM installed/compiled in and just issuing "apm --suspend" puts it into a deep enough sleep that sitting all day only knocks a few percentage points off the battery. |

That sounds pretty sweet dambacher, wish they had a patch for beta kernels. _________________ -Phil Crosby |

Hi Reformist!
You don't need to patch a beta-kernel. ACPI as well as swsusp are included.
I just can't use a beta kernel, my bcm440 network card driver does not work with it and the b44 driver of 2.5.68 is buggy for me.
Greetings

yeah, I would be using the betas (I have many installed) but I can't get my wireless pcmcia network card working either... so I'll be patching 2.4.20!! _________________ -Phil Crosby |

Well, the 2.5.69 etc. come with swsusp already patched in them (or at least the mm-sources do), which is great, but it seems the location of /proc/sys/kernel/swsusp is different, and therefore the "hibernate" or "suspend" script does not work, because it tries to echo values to a device that does not exist.
Anyone got this working with any newer 2.5.x kernels? Is there a modified script somewhere? _________________ -Phil Crosby |
