Hello, As the subject line summarizes, I do not get any ACPI events when I unplug/plug the AC adapter on a Sony Vaio VPCS12X9E. The laptop is currently running an up-to-date installation of Kubuntu 11.04, but with a manually compiled vanilla 3.0.3 kernel. For the record, the same problem also exists with the stock version 2.6.38 kernel that comes with Kubuntu 11.04. I have also reported this bug at https://bugzilla.kernel.org/show_bug.cgi?id=41762 Since I am going to travel soon and lose physical access to this hardware, I wanted to ask if there is anything I could do to debug this problem. I have included the acpidump and ACPI debug outputs in the bug report. Any help would be appreciated.
