Hi all,
It may be really a dumb question, but I've really no idea.
I have a Samsung P10 and found at behnel.de & SF-ACPI page some
instructions to patch the DSDT table under Suse 9.1pro. I followed those
as close as I can and I guess ACPI works somehow. Well, wakeup after
sleep and CPU-throttling doesn't work though :(
Now to my dismay the battery stopped charging at all, it is completely
empty. No matter what I do, it doesn't get charged. The battery is about
2 yrs old but was pretty OK before, i.e. lasted about 1.5 hrs unplugged.
Is it possible for DSDT patches to blow up the battery & charging units
or you think the battery's (physically) died all of a sudden?

Well, hard to say, everything is possible, and so far I seen a lot of
funny stuff, but every time it recovered at least after removing
battery and removing AC for more than minute.

Can I make a gess that your battery is Lithium Ion? LiIon batteries
typically last for 2 years *after manufacture*, irrespective of how many
times they are charged and/or discharged. See:
http://www.batteryuniversity.com/parttwo-34.htm
It may be that your battery has reached the end of its life, nothing to
do with ACPI.
cheers,
Rich

Well, it's a very informative page (especially the fact 40% being the
optimal charge) thank you. But the battery's died pretty quickly. I
mean, my common sense says no battery goes from 1.5 hrs to 0 in ~one week!
Anyway, I'll think of something.
peace
