Thanks for the suggestion. I knew that guide, but I thought it contained only suggestions to improve C-state handlng, not to enable them. I did all the /boot/loader.conf entries suggested there, but I still do not have C3. Changing everything in BIOS to "maximum battery" does not help, either. Any more ideas? iasl gives me "1 Errors, 17 Warnings, 5 Remarks, 2824 Optimizations" for my dsdt. Do these need to be fixed? (The error seems pretty harmless concerning '_HID, "*pnp0c14"', which should be alphanumeric.) Cheers, Jan Henrik
