[ACPI] Strange Compaq Evo (N150)

[David D. <do...@pl...>]

Hi everybody,
I'm a complete newby on ACPI stuffs, and I ask you to forgive my poor english
level.

Ok, the facts :

I have a Compaq Evo N150, and I'm using 2.4.17 kernel, with ACPI  20011218...

Ok, It boot OK using ACPI, but I couldn't have a battery status nor the
ac_adapter status...
So I tried to look at DSDT code (well, as I told before, a week ago I didn't
had any idea on how ACPI stuffs works, so...).

First of all I was really surprise to notice that the "ad" disass from
phoenix reported errors in the code I dumped from bios.

But then I looked smarter and realized (according to the errors I had when I
tried to view ac_adapter status (actually it was :
"Ds_create_operand     : Object name [\_SB_.DFEC] was not found in namespace"
))
and I realized that DFEC was not declared in the right scope...

More, it was used as a function in the code, but it is an Int !

I am not very sure, but can Compaq (ACPI co designer) provide such a buggy
Phoenix (ACPI co-designer too) ACPI code ???

Well, I tried to correct things, and Battery and AcAdapter  work fine now. I 
put my code attached ( and the original dump too : if someone understanding 
well that code could tell me if I'm doing things OK...).

But I still have problems :
- S1 level just darken the screen (backlight still on) then I can't do
anything else but reboot.
- others Sx levels do not affect the laptop
- AC_Adapter do not send an event to notify the change of state (plugged or 
not) : I'd like to have this stuff working to change my HD spinout time 
according to this state....
- Other things I think...


Thanks for any help
