Created attachment 32432 [details] lspci output System refuses to recognise the battery in the Acer Aspire One 521 netbook. The system is based off of the AMD M880G chipset. I've attached the lspci and cpuinfo from my Ubuntu system, but if anything else is needed or if I can help test anything in any way, I would be more than happy to facilitate. The Kernel is the latest mainline (as of 2 Oct. 2010) for Ubuntu.
Created attachment 32442 [details] output of /proc/cpuinfo Dunno if it'd be useful or not...
please attach the acpidump output of this netbook. please attach the output of "grep . /proc/acpi/battery/*/*"
Created attachment 32772 [details] results of acpidump
Created attachment 32782 [details] result of less /proc/acpi/BAT1/* no battery detected for all sources available in the /proc/acpi/BAT1 directory.
this looks like a duplicate of bug #15707. Michael, please verify if the patch at https://bugzilla.kernel.org/show_bug.cgi?id=15707#c2 helps.
Upon re-doing my gentoo installation, I've noticed that browsing through /proc/acpi/processor/CPU0/throttling has a "diff_ec_try_econ.patch" in it. Is this the same one that you are pointing me to, or is the linked patch file different? If it is, then I'm still having the same issue. If it isn't, then how exactly should I apply the linked patch? Browsing through that file shows that it's expecting kernel version 2.6.33... (I've never used a patch file before).

I don't know how to customize a kernel in gentoo linux. But I think you may get some help at http://bugs.gentoo.org/

Gentoo pulls in the upstream from kernel.org, and the version I'm using are the vanilla-sources, which are the supposedly unpatched, 1:1 of what's on kernel.org, so...

I applied the patch above to Ubuntu 10.04 kernel 2.6.32-25 on my AO521 with BIOS 1.08. Battery status and thermal zone appear to be working. Neither were working before applying the patch. I'll attach output of grep . /proc/acpi/battery/*/* /proc/acpi/thermal_zone/*/* Hope this helps.

I applied the patch and this is indeed a duplicate of bug #15707. Thank you very much for helping me through this. I'm going to mark this a resolved duplicate of 15707. *** This bug has been marked as a duplicate of bug 15707 ***
