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

[Alexander Hoogerhuis <alexh-rpjHciJLgqZBDgjK7y7TUQ@public.gmane.org>]

I've had some limited success now with getting things to work on y
Compaq Evo n800c. Currently I'm running on 2.4.20 with the ACPI patch
version 20021212. It does not apply cleanly to my version of 2.4.20,
and I don't have access to the net just now to see if it's my version
of the kernel or if it's the ACPI that is bad. However, its just parts
of the mpparse.c file it complains about and I'm on a UP system.

Basically what I've done is to get the DSDT form my system, disasemble
it with iasl, recompile it with iasl after only fixing the *'es on the
PnP resources, and not altering C11D->BAT1, etc.

The only thing I cannot do is to display the content of
/proc/acpi/battery/C11D/state. What whill happen is that it will
happily show me the content and then the machine will coldly restat
after a few seconds. Doing a "sync; cat /proc/acpi/battery/C11D/*>
blah; sync" left me with this content though:

remaining capacity:      1913 mAh

And it's been a long time since I've had much physics, but the design
capacity doesn't seem right to me. I'm able to run about 13-14 mins on
battery, before the machine dies, from a fully charged battery.

After rebooting, this is what the entries said:

It's also interesting to note taht with the new DSDT I chopped
together myself, the LED indicating it's time to get plugged into an
AC adapter or loose work, does not work anymore.

Currently my bootlog gives me this:

For what it's worth, at least I've made some progress, and my machine
seems to at least know when to throttle up and down from the C-states:

lapper root # cat /proc/acpi/processor/C000/power 
active state:            C2
default state:           C1
bus master activity:     ffffffff
states:

   *C2:                  promotion[C3] demotion[C1] latency[002] usage[00198960]
    C3:                  promotion[--] demotion[C2] latency[085] usage[00000148]

If anyone have pointers on how to take this further, please let us
know? :)
