Same errors here as the OP, same hardware (HP Pavilion dv6); error messages occur whenever AC power is plugged/unplugged.

Repeated errors in /var/log/syslog:
May 5 12:55:50 flolap010 kernel: [13957.798431] ACPI Error (psargs-0359): [^^^RP05.J380.D3EF] Namespace lookup failure, AE_NOT_FOUND

As a consequence (?) laptop-mode-tools do not detect the switch from AC to battery power (and vice-versa), and neither does gnome-power-manager (system tray battery icon remains in "charging" state).
