Raffay Posted December 19, 2019 Share Posted December 19, 2019 I want to disable dedicated GPU, GTX 1650 but using -wegnoegpu causes by maximum brightness to drastically get reduced. Is there a fix for this so I can disable the dGPU to maximise battery life? CLOVER.zip Link to comment Share on other sites More sharing options...

Raffay Posted December 19, 2019 Author Share Posted December 19, 2019 @Jake Lo Thank You. I did it but it has the same effect as wegnoegpu. My maximum brightness drastically reduced Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 19, 2019 Moderators Share Posted December 19, 2019 Does the brightness slider show up? Link to comment Share on other sites More sharing options...
Raffay Posted December 19, 2019 Author Share Posted December 19, 2019 @Jake LoYes there is a slider. I can increase and decrease the brightness as well. Its only that the range of beightness is reduced drastically. My maximum brightness is very very low after disabling dedicated GPU Link to comment Share on other sites More sharing options...

Raffay Posted December 19, 2019 Author Share Posted December 19, 2019 @Jake Lo I have added these files along with SSDT-Disable-DGPU.aml. Seems my brightness is perfect. Can you tell what these SSDTs have done? Also how can I be 100% sure that my dGPU is in fact not drawing power? Thank You Link to comment Share on other sites More sharing options...

Raffay Posted December 19, 2019 Author Share Posted December 19, 2019 @Jake Lo I searched for keyword “dgpu” and following result showed. Seems dGPU is off? I’m trying to learn so I’ll really appreciate if you can point how exactly I can search the IOReg myself. Thank You Link to comment Share on other sites More sharing options...
