N600c/N610c fan not working problem

N600c/N610c fan not working problem

[Markus Joschko]

Hi,
I recently bought a Evo N610c Compaq notebook and tried to install gentoo
linux with the latest acpi patched gentoo kernel.

Like others on the mailinglist I noticed that the fan isn't working as soon
as ACPI is enabled. Passing acpi=off to the kernel during boottime brings
back the fan.

Is there any solution for the fan problem yet? Can I help with providing
some kind of data?

Ciao,
 MArkus

I have this same laptop, my experience:

- fan & battery modules failing during load.  I mean that they don't
  load, there is not any error message or similar.  rest of ACPI
  modules load well and values make sense.

- 20021101 with debug messages disabled work, with messages enabled
  don't boot (expend more than 2 hours and still haven't finished the
  boot).  I tried with the s/_HIGH/_LOW/ patch that appeared in the
  list, and it still don't work.

- There is something wrong with 20021101, as it don't boot in another
  laptop (HP Omnibook XE3) when messages are enabled, in this laptop,
  it is the case that _no_ message is printed during the booting of
  the kernel, ZERO output at all (others has also reported this
  problem).

- I tried (in my ignorance) search why the fan and battery modules are
  not loaded,  I arrived that fan required HID of PNP0C0B and battery
  one of PNP0C0A.  I run:

  ./acpidmp DSDT > dsdt (file included)

quintela$ cat dsdt | ./acpidisasm | grep PNP0C0B
08059d21:       "*PNP0C0B"
08059d4a:       "*PNP0C0B"
08059d73:       "*PNP0C0B"
quintela$ cat dsdt | ./acpidisasm | grep PNP0C0A
08058ae0:       "*PNP0C0A"
08058ba0:       "*PNP0C0A"

  I found tha the strings are there, but the format of the disasemble
  is not _intuitive_ at all :(  (Yes, I haven't read the ACPI
  standard, perhaps once read, things make more sense :p).

Will try kgdb later today and see why the thing is failing.  If
someone has some idea on how to fix that, I will like to hear.

Later, Juan.

AW: N600c/N610c fan not working problem

[Markus Joschko]

Hi,

>Heh, kernel version would be helpfull.
2.4.20-r6

in the mean time I have corrected the dsdt with guidance from presario/800v
users.
I did: remove * from object names. Removing an ALIAS line, changing method
references to absolut references.

Now the fan is working and the notebook switches off if I do a shutdown. The
battery is identified. Nothing more tried yet.

But I have a lot of error reports during the booting of the notebook. May be
someone can explain/help me with them.
(OT: is there a possiblity to search the acpi-devel mailing list? I can't
find any advice on the sourceforge page. Would make research a lot easier):

PCI: Using configuration type 1
	ACPI-0243: *** Error: Could not install Pci_config handler for C03A,
AE_ALREADY_EXISTS

and

ACPI: System [ACPI] (supports S0 S3 S4 S5)
	ACPI-1155: *** Error: Method execution failed, AE_AML_BUFFER_LIMIT

and

ACPI: AC Adapter [C186] (on-line)
	ACPI-1155: *** Error: Method execution failed, AE_AML_UNINITIALIZED_LOCAL


Thanks,
 MArkus
