Shutdown doesn't Turn Off Power

rashid68 · 05-23-2008, 07:23 AM

Hi

I have servers that doesn't turn off the power after successful execution of "shutdown -h now" or using Shutdown from the Gnome interface. I have to manually press the power buttons on all servers. I have RedHat AS3 with kernel 2.4.21-50.

Please help.

Probably due to ACPI things; the shutdown process usually ends with halt, after which acpi should turn off power. Do other power management things work, or do you get errors about acpi?

Hi

Sorry for my ignorance as I am new to Linux. I looked for any process running for acpi but there is nothing. As far Power management is concerned, I use only the screen saver and that is working fine.

Thanks

what are you using for boot? Grub or Lilo? If you are using Grub when the boot menu comes up, hit "a" to add options to the kernel and add "acpi=off" at the end of the line. then boot, then try to shutdown and see if it powers off. If you are using Lilo you can go into lilo.conf and add the same "acpi=off" to the end of the kernel line, run.. run lilo then reboot, once it's booted try to shutdown -h.
