Dell laptops and desktop can be monitored by SMM methods as mentioned is the old topic I made a plugin SMIMonitor for FakeSMC in 2014 but it was 32bits and was not working. Only now I made it to be 64bits (as darkvoid did with kozleks branch) and got positive results and after heating So I have monitoring of 4 additional temperature sensors (CPU Proximity, GPU, DIMM, and Motherboard) and a CPU fan which initially stay at 0 rpm and start rotating after heating with 2882rpm. Moreover I implemented a function for brave people to control fans sudo SMC_util3 -kF0As -w2 The last digit 2 is a FAN speed you want to set 0 = Off 1 = Low 2 = High If you have more then 1 fan then you can manage other one by choosing next key F1As, F2As etc. Precaution! Writing the fan speed is dangerous and may cause a computer damage. Do this at your own risk! Note. SMIMonitor.kext will work only with FakeSMC v3 provided with HWSensors3 in my signature. Official release at sf.net contains SMIMonitor without write possibility. Please test and report your successes and fails. SMIMonitor.kext-110.zip SMC_util3.zip smcwrite.zip
Guys, Don't mix 6.18 and 3.41. There are three different projects for monitoring temperatures, voltages, fans speed and other hardware parameters: Initially it was FakeSMC with plugins for producing SMC keys for hardware parameters for different hardware. But sometimes ago Kozlek separated own version of FakeSMC and producing new set of plugins while I stay with good working version 3. So.. 1. FakeSMC v3 with Hardware Sensors3 which I still supported. 2. FakeSMC v6 (rev1800) by Kozlek and supported by Rehabman. AFAIK both are abandoned and the project is not supported. Or may be maintained by coauthors. 3. New VirtualSMC by vit9696 with own set of sensors kexts. It depends on Lilu.kext. The project is in active development. All three project have incompatible interfaces sensors<->SMC so they are incompatible with each other. There are applications for monitoring hardware parameters and they commonly depends on these projects. 1. iStat, iStatMenu, iStatPro compatible with real Macs because they use SMC keys just like those presents in real Macs. 2. HWMonitorSMC by Navi (initial codes from Kozlek) used in my HWSensors3. 3. HWMonitor by Kozlek with graphics like in IntelPowerGadget used in his HWSensors version. 4. HWMonitorSMC2 by Vector_Sigma tends to be universal supporting all project. It also may use sensors information produces by Apple graphics and by IntelPowerGadget. Let us discuss here differences and common ideas for this projects.
Slice posted a topic in Hardware SensorsLaptop battery monitoring Using this driver you have to exclude other battery drivers: ACPIBatteryManager, AppleSmartBattery and so on. This driver assumes to using HWSensors3 with FakeSMC 3.5 as being part of it. 19.01.2018 Updated version of VoodooBatterySMC will get extended battery information and so it will be more exact.
