The great news is that the laptop does well with such a drop onto a concrete floor. The bad news is that the hard drive does not! So I'm going to start over with the newer Konstantin patch and 10-current= =2E Maybe OpenBSD has a defined quirk or a different way of querying ACPI display features that is avoiding a quirk or "new way of doing things" at lenovo. "Our" acpi video kernel module does attach, but some data looked bogus. Whatever you do don't set debug.acpi.reset_video! It required removing the battery, although if you need an emergency discotheque, it might suffice. Matt
