I would try it with passing acpi=off,apm=off to the kernel at boot (or was it noacpi,noapm???)
Does not make many sense for working with a laptop, but could help you tracking the problem :roll:

Thank you for your post and sorry for late reply I am a bit busy with exams.

I have tried with noacpi, noapm and with only noacpi gets rid of the error but that means no power save and shorter battery life isn't it?? :roll:

What could be the problem, any ideas?

As I said, it was only for testing if it is an ACPI problem.

So APM can shut down your computer.

ACPI seems to have problems with one or more chips in your laptop. I would try a brand new kernel an see if the problem is still present. If yes, you still have some options.

- Remove drivers for the less relevant parts one by one to find the problem
- live with it :wink:

- join the ACPI herd and try to fix the problem at lowest possible level :lol:

Sorry, but there is just no handbook on such problems. I spent weeks searching the web how to get around some ugly errors in the ACPI bios of my laptop, to get some more juice out of my processor.
