Actually, the "standard" internal ACPI brightness level struct (BRTN in the DSDT) is laid out as: * "Full power" value (one byte, the value at which the brightness should be set on AC by default) * "Economy" value (one byte, the value at which the brightness should be set on battery by default) * Actual values (N bytes, up to Max but frequently not) So, no, that value indeed sounds correct. On my laptop the value is: 80 47 0 7 13 20 27 33 40 47 53 60 67 73 80 87 93 100 What revision of -CURRENT are you running?
