Hi, with SLES11 SP1 (current kernel), acpi reports: linux:~ # acpi -cV No support for device type: battery Thermal 1: ok, 8.0 degrees C No support for device type: ac_adapter I doubt that 8ÂC as the ambient temperature is around 20ÂC. When comparing with the IPMI data I see this: linux:~ # ipmitool sdr UID Light | 0 unspecified | ok Sys.
