Laptop sensors

[kosakgroove]

Hi great users of this forum


I have a big doubt regarding my laptops sensors. I am currently using HWMonitor in OSX 10.11.3, which as you know, in conjunction with FakeSMC kext and with FakeSMC_sensors kexts gives a lot of info about your build.


I am using FakeSMC_ACPISensors kext and FakeSMC_CPUSensors kext.
In HWMonitor I get detailed info about my CPU’s cores temperatures, about the hard drive temperature, about the CPU frequencies, multiplier, and about the CPU Power consumption.


I am doing this on the first laptop of my signature. I would like to know If I can be able to get fan speed data and battery temperature data. Thanks for your time


I am open to trying any suggestion given!
Thanks in advance!

Fan speed (no support in FakeSMC/HwMonitor for battery temp) requires investigation (reverse engineering) and DSDT patches to interface with ACPISensors.kext.

Any idea how I could start writing a DSDT patch? What device is it on normally?

Is there any utility that would support fan speed readings and/or battery temp? If no, what would be my first step in order for this to work?

It varies. The data is usually in the EC. There may or may not be a Field declaration for it.

Look at your DSDT and try to determine if there is a field for the data you want. You can use ACPIDebug to print the data to system.log. And you can use RW-Everything to examine SystemMemory and EC regions.
