I forgot to mention that when I unplug the laptop there are no power saving options or options to saving info. Power just shuts down when battery runs down. It seems something is broken in your ACPI, but definitely this is not acpid issue. Reassigning to kernel for further investigation. Created attachment 592830 [details]

dmesg output using the latest EL 6.3 kernel
Latest Enterprise Linux kernel 6.3 with dmesg output. It should be noted that the latest fedora kernels have the same issue with this laptop. Also, windows detects the battery without issue. I am more than willing to try running a test kernel if that would help things along. I would rather not use my Windows 7 partition unless absolutely necessary. I am at your disposal. Thank you.

dmesg output using the latest kernel from the elrepo repository (kernel-ml-3.5.2-1)
I found a newer kernel from the elrepo repository and decided to see if the problem was resolved and it wasn't. I will also write a buf report on the elrepo site referring to this bug. Thanks.

Having been vectored here by a report in the ELRepo Project bug tracker (http://elrepo.org/bugs/view.php?id=300) regarding this issue, the first thing I would advise is a BIOS update from Acer.

dmesg output using the latest EL 6.3 kernel and ACER Phoenix BIOS (1.6)
It looks like the latest ACER Phoenix BIOS (1.6) fixes the battery detection issue. I apologize for wasting everyone's time. There are other issues regarding detection of the CPU heat sensors, but I imagine I will have to go back and open a separate bug report. Anyway, I included the dmesg report for informational purposes. Thank you.
As per comment 9, I'm closing this BZ. Thank you for the update. -Lenny. |
