Did you read the top marking of the chip? Me, I am 100% certain that the above is NOT an EMC2103-2, because it is connected to the LPC bus while the EMC2103-2 is an SMBus chip. Can't be the same chip. The chip above is likely to be a HP-specific Super-I/O chip, maybe Juerg (Cc'd) can identify it. There is no guarantee that it includes hardware monitoring features though. > I can > load the driver with modprobe emc2103, but nothing happens.

Driver was contributed by SMSC themselves (Steve Cc'd), I'm fairly certain that they tested their code. What could happen is that the SMBus controller to which the EMC2103-2 chip is connected, is not properly supported on your system. Maybe it is a very recent chip we don't support yet, or maybe ACPI gets in the way and prevents the driver from binding to the chip. I'd like to see the complete output of sensors-detect and lspci. Note BTW that it is very frequent for laptops to not include complete hardware monitoring chips. Furthermore, the monitoring chip is usually hidden behind ACPI so all you get is the limited ACPI thermal zone interface, or some proprietary interface. You may want to give a try to the hp_accel and hp-wmi modules for laptop-specific features support. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
