I saw a lot of ACPI errors when I did a dmesg, so I followed this guide:
http://crippledcanary.se/acpi-proble...spire-3003lmi/

I think there are less of them now, but there still are some.

[4294734.655000] ibm_acpi: ec object not found
[4294734.696000] ACPI: Battery Slot [BAT1] (battery present)

[4294743.584000] apm: BIOS not found.

And a bit further:

[4294747.248000] mtrr: 0xe8000000,0x4000000 overlaps existing 0xe8000000,0x1000000

[4294771.518000] ACPI-0362: *** Error: Looking up [Z007] in namespace, AE_NOT_FOUND

This search node error keeps repeating itself. Any thoughts here?

Hmm, I don't think I solved anything. If you follow the link I posted in my previous post, you can see the author says he exactly solved the errors I'm still getting.

Although I seem to have solved something. I couldn't wake up the notebook when in sleepmodus, now I can. Battery and hibernation still don't work though.

Anybody an idea?
