I have tried various fixes to similar power problems that i've found, e.g. adding apm power_off=1 to /etc/modules but none have seemed to work so far. I'm relatively new to Linux so any help would be greatly appreciated.
I think you need to add to the line in grub where it says the kernel ACPI=off on the end if I remember rightly. Is it an old PC? they have problems with shutting down properly..
see here:
Kernel Options
Note: These options are used by the kernel, and will apply to any installation at any time. The file "Documentation/kernel-parameters.txt" in the relevant linux-source package provides more information.
Option
Impact
vga=xxx
Set your framebuffer resolution to VESA mode xxx. Check here for a list of possible modes.
acpi=off OR noacpi
This parameter disables the whole ACPI system. This may prove very useful, for example, if your computer does not support ACPI or if you think the ACPI implementation might cause some problems (for instance random reboots or system lockups).
acpi=force
Activates the ACPI system even if your computer BIOS date is older than 2000. This parameter overrides acpi=off and can also be used with current hardware if the ACPI support is not activated despite apm=off.
pci=noacpi OR acpi=noirq
These parameters disable the PCI IRQ routing
pci=acpi
This parameter activates the PCI IRQ routing
acpi_irq_balance
ACPI is allowed to use PIC interrupts to minimize the common use of IRQs.
acpi_irq_nobalance
ACPI is not allowed to use PIC interrupts.
acpi=oldboot
Deactivates the ACPI system almost completely; only the components required for the boot process will be used.
acpi=ht
Impact Deactivates the ACPI system almost completely; only the components required for hyper threading will be used.
noapic
Disable the "Advanced Programmable Interrupt Controller (APIC)".
nolapic
Disable the "local APIC".
apm=off OR noapm
Disable the Advanced Power Management.
irqpoll
Changes the way the kernel handles interrupt calls (set it to polling). Can be useful in case of hardware interrupt issues.
acpi.power_nocheck=1 OR acpi_osi=linux
Disable the check of power state or changes the OS compatibility reported to the BIOS. Necessary on some broken BIOSes to make temperature/fan control work.
