How can I find out which entry of lm-sensors corresponds to which hardware component for my HP EliteBook 8540w, with Intel 5 series chipsest?
I have a laptop (HP EliteBook 8540w, with Intel 5 series chipsest) that keeps overheating.
It is quite old already, so I did open it up and replaced all the dried thermal grease / pads with new grease. It did help, but looks like I missed one component.
Here is the output of lm-sensors during idle for some time (with open firefox)
acpitz-virtual-0 Adapter: Virtual device temp1: +68.0°C (crit = +127.0°C) temp2: +0.0°C (crit = +127.0°C) temp3: +37.0°C (crit = +128.0°C) temp4: +57.0°C (crit = +127.0°C) temp5: +77.0°C (crit = +115.0°C) temp6: +20.0°C (crit = +128.0°C) temp7: +69.0°C (crit = +128.0°C) temp8: +68.0°C (crit = +128.0°C) temp9: +0.0°C (crit = +128.0°C) temp10: +88.0°C (crit = +128.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +68.0°C (high = +84.0°C, crit = +100.0°C) Core 1: +68.0°C (high = +84.0°C, crit = +100.0°C) Core 2: +68.0°C (high = +84.0°C, crit = +100.0°C) Core 3: +68.0°C (high = +84.0°C, crit = +100.0°C)
For me, it looks like, the component reporting as temp10 could be the problem. How to find out what actual hardware component is reporting as temp10? (The laptop usually overheats and shuts down during computational desktop load, no gpu load involved) I tried reading the manual of the chipset (above, section 22.2, p868, Thermal sensor registers) but I didn't get a clue. Here is a similar list for a thinkpad. I'm looking for something like this.
Note: I'm not asking for help with my cooling problems (But of course, tipps as comments are welcome.)
