Hi, I have used the lm_sensors package to try and look at the i2c devices on a Toshiba Tecra 8100 laptop with little success. It now overheats and crashes with extended use. I do not know wether it was due to probing the i2c bus and changing something or some other unfortunate combination of events that culminated at about the same time. So since I saw the warning messages for IBM laptops I thought I would mention it - just in case. I would be happy to try and trouble-shoot what may have happened if someone could give some guidance what to try... CPU: Pentium 3/speedstep 750MHz, 128M RAM, 20G HDD,...
