Mode switching never works

I have a Zephyrus 16 gu603z and the mode switching never worked properly. Even tho i put it in eco mode after standard,when I put it to sleep sometimes it just heats up without doing anything. Fans start every 5 minutes and it uses the battery. Sometimes the problem happens the other way around when the gpu doesn't activate at all. I tried Ghelper and it didn't work. Can someone please tell me how to fix these bugs
