Mandriva Spontaneously Shutting Off

[lahonda_99]

Anyone heard of Mandriva shutting down randomly? The whole computer turns off in one stroke, no shut down process happens. Everything powers off.

I changed hard drive, power supply, CPU and motherboard. I've not changed the power surge or case, both seem to be working fine.

Where should I look for possible logs that might have been written when the system does this random power off?

Oh dear! It might be to do with ACPI power management. Sometimes booting with these options can help:

linux noapic
linux nolapic
linux noapic nolapic

I've never needed to do that myself, however ACPI can also be toggled on/off from your BIOS. This is very generic advice, but if you search these forums you'll find more details about this.

I know that the 'noapic' boot options can be altered in the Mandriva Control Centre, or given to your boot manager (Lilo / Grub) at boot time.

fingal,
I went into the Mandriva Linux Control Center then the 'Boot' submenu.
Then I unchecked "Enable ACPI" in the "Set up how Linux Boots" menu.

My computer is running fine and has not randomly shut off since yesterday
I'm still not sure exactly why it was doing that, but at least it works.

Thanks for the great advice!
