Bug Description
The system encounters an error while trying to read the status of the AC adapter and, as a result, it behaves as if the AC adapter were plugged. The relevant dmesg lines seem to be the following:
[ 0.944150] ACPI Error (psargs-0359): [\_PR_.CPU0._PPC] Namespace lookup failure, AE_NOT_FOUND
[ 0.944156] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.
[ 0.944207] ACPI Exception: AE_NOT_FOUND, Error reading AC Adapter state (20090903/ac-140)
Additionally, the system detects the battery but cannot read the charge status and, as a result, it behaves as if the battery were fully charged. The relevant dmesg lines seem to be the following:
[ 0.957281] ACPI: Battery Slot [BAT1] (battery present)
[ 2.224333] ata2.00: ACPI _SDD failed (AE 0x5)
[ 7.565299] ata2.00: ACPI _SDD failed (AE 0x5)
[ 7.565303] ata2.00: ACPI: failed the second time, disabled
I'm going to attach the full output of dmesg | grep ACPI.
I also tested this under 2.6.34, using the 2.6.34-
I'm going to attach the full output of dmesg | grep ACPI under 2.6.34 as well.

Hi Tommaso,
If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text. Please let us know your results.
Thanks in advance.
