[Bug 578894] [NEW] Cannot detect AC adapter status and battery charge status on Acer Aspire 4820TG

[Tommaso R. Donnarumma]

Public bug reported:

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_.PCI0.ACAD._PSR] (Node ffff88013384d720), AE_NOT_FOUND
[    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 2.6.34-020634rc7-generic
#020634rc7 package from the Kernel Team PPA. With this kernel, the ACPI
error is gone, but the AC adapter is always detected as plugged even if
unplugged. The battery related behavior is the same: that is, the
battery is detected but the battery charge status cannot be read.

I'm going to attach the full output of dmesg | grep ACPI under 2.6.34 as
well.
