It is difficult to help you, given the little detail you provided. "Not working" isn't a proper way to describe the situation: there are many ways thing can fail. So I can only give you this general piece of information: most laptops don't have a usable hardware monitoring chip and you have to rely on ACPI for thermal management. The standard ACPI interface provides temperature values but no fan speed values. We have a few BIOS drivers for specific vendors, but we don't have any for Sony. So I am not surprised if you don't get a fan speed reading on your Sony laptop - I don't get any on mine either. -- Jean Delvare http://khali.linux-fr.org/wishlist.html _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
