with linux.. ubuntu

sudo apt-get install acpidump iasl


Then run the following commands on terminal:


mkdir ~/acpiinfo ; cd ~/acpiinfo

sudo acpidump > acpidump.txt

# enter password

sudo acpixtract acpidump.txt

ls *.dat | while read i; do iasl -d "${i}"; done

seems like structuring doesnt comply to acpi specs for compiler.

structuring is a little bit mixed up. not sure of fix.

im sure someone eventualy figures it out.


u can also rebuild dsdt from scratch from parts of this one.


example: i used g31m-es2L dsdt i extracted and i later found a very small version of it (minimal) i compared the info and found a line for the memory was not same

so i fixed and it works with it missing 1/2 the dsdt.


in your case its a complex laptop not a desktop so it might be harder... find a dv6 model thats similar and compare .dsl in text wrangler ?


what model dv6 ?? under it under battery usually says dv6-####

0 Errors, still warnings and remarks, it's a start.


Edit: Warnings also gone, you still are missing 2 brackets, was a on the fly fix, no patches applied, if you need them too, let me know.

Thank you very much now I have a full working system! I edited your dsdt to add all fixes needed for my system:

  • Fn Keys enabled
  • Brightness Fix: need to use generic brightness noslide edition
  • HPET Fix for native power management and sleep
  • Battery information are ACPI 3.x and 4.x compliant so voodoobattery read them well
  • LID closing fix: now go to sleep when closing LID
  • Temperature correctly reported and correct fan speed applied
  • Patch for loading AppleLPC.kext and keep cpu more cooler

If anyone interested:

EDIT: Added LPC patch
