Re: No battery information - Compaq Evo N800v, 2.4.20pre8, acpi 20021002

[Kevin Schmidt]

I have a Compaq evo n1000v which is very similar (the dsdt says n800).
I am running 2.4.19+xfs+acpi-20020918 with a patched dsdt.
The dsdt changes were:
1. Deleted the leading from variables flagged by errors as suggested
in other messages to this list.
2. Added External definitions for variables not found
and commented out the Alias line that caused a compiler error. This
allowed the dsdt to compile with some warnings about missing return
types. I tried adding zero returns to those, and the warnings went away
but I could not detect any change in the way the machine ran.

After the dsdt changes, the ac_adapter was detected properly and it detects
when it is plugged in or removed. The lid switch and the
power button give events and I see /proc/battery, but the battery is
not detected. There are still a couple of errors in dmesg from the
dsdt.

I know next to nothing about what this really does, so use this at
your own risk. It does appear that the problems are dsdt related.

You may find that you need to power-up the notebook with the AC
unplugged.  There seems to be a problem on many of the Compaq systems
where the thermal and battery zones do not properly initialize if AC
power is applied at power-up.

My Compaq Presario 2710CA has this problem, and if I power-up with no AC
to after the BIOS has initialized (Boot loader appears) then all is OK
with both the battery and thermal zones.  The later BIOS updates from
Compaq have still not resolved this issue.

Hey,

Thanks for writing back...much appreciated. I must admit, its quite over my 
head, so when you say you know next to nothing, I'm waaay back at the 
starting line! 

I was wondering whether you could post your tweaked dst...I could take it for 
a spin and see how it goes.

I've also mailed Compaq requesting their AML for the N800V...might not get 
anywhere, but it can't hurt.

Cheers

Mark

Hey,

Thanks for writing back Troy...I gave that a try, but no joy. I'll have a poke 
around my AML and see if I can puzzle something out.

Thanks again,

Mark
