Laptop enters sleep mode on AC-power

[Guy Van Sanden]

After a recent update of Oneiric, my laptop enters sleep mode even when connected to AC (this setting is not checked and even greyed out in the power settings dialog.

The acpi command clearly shows that AC online/offline is detected correctly.
