Not cached, the read method pokes an ioport (0xb2 - field called SMIC - I guess it's system management IC), and reads back a value from the memory. This is the Q-FAN setting though, probably read from the non-volatile store, the hwmon chip is not queried directly (nor programmed AFAICS). My guess is that at boot the BIOS reads the settings a programs the chip - and forget do it when coming out from S4; did you try and change the shutdown method? i.e.: echo shutdown > /sys/power/disk Luca _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
