I do use two or three different PSUs, they may have different ratings. The one I have in front of me is 65W, and I do get 0x6040 when I plug or unplug it today. The other one is at the office and I'll check on Monday. Looking through syslog, I do have a lot of pairs of "unhandled HKEY event 0x6040" followed immediately by "EC reports that Thermal Table has changed", but there are also a few Thermal Table changed without a preceding HKEY event. Perhaps 90% of "Thermal Table has changed" have a HKEY before them. There don't appear to be any HKEY 0x6040 without a "Thermal Table has changed" immediately after. -andy
