problem shutting down an old pc.
  • SlavaxSlavax May 2010
    When I shut down my old pc, it remains on. That is, on the monitor I read "Computer halted" but all the led lights remain on and the power is not turned off. With another distro I use, the options "acpi=off apm=power-off" on the kernel line solved the problem. But the same options on the slitaz kernel line yield no result (that is, computer does not shut down).
    Is there any other option I can use?
    Thanks.

    When you click the "Shutdown computer" button on the Slim logout box it uses
    /sbin/poweroff built into busybox.
    Open xterm and type 
    poweroff --help

    One of the options is -f switch for Force poweroff
    Try in xterm 
    root@slitaz: poweroff -f

    If this works open /etc/slim.conf as root in text editor
    add -f switch to halt_cmd like /sbin/poweroff -f

    If no luck check power options in motherboard bios.
    Maybe slitaz accept kernel option acpi=force

    in boot options, i experiment with some or all of the following lines:


    acpi=off
    apm=on
    power_off=1


  • SlavaxSlavax May 2010 
    poweroff -f
    hangs the screen
    acpi=off apm=on power_off=1
    has no success
    acpi=force
    the same

    Things to check-

    Try as root user.

    Check if wake on lan or other wake feature is enabled in bios or other setting.

    I have tried to use acpi=force on the kernel line.
    But:
    root@slitaz:~# dmesg | grep ACPI
    ACPI Error (tbxfroot-0219): A valid RSDP was not found [20090320]
    ACPI: Interpreter disabled.
    pci 0000:00:07.3: quirk: region 0400-043f claimed by PIIX4 ACPI
    pnp: PnP ACPI: disabled

    what does this mean?
  • ossoss May 2010
    Sorry, post mistake.
  • SlavaxSlavax May 2010
    Is it possible that neither ACPI nor APM is installed?
    Why there isn't any apm package in tazpkg?
  • mojomojo May 2010
    ACPI or older APM are on the motherboards bios eprom chip
    The linux kernel depending on it's configuration when it's compiled is what interacts with the bios on startup.
    You've tried passing options to the kernel at boot which didn't work.
    You made no mention of trying different settings in your bios.
    Hit DEL or F2 key before bios boot ends to get into the bios menu.
    Start with power management,try one setting change at a time,save, boot, see if it'll shutdown. If you have a setting called "Plug and Play OS" No , Power Management enabled
