| I had a similar experience with my Asus Zenbook Prime ultrabook. I noticed that the very loud fan was running a lot faster and more frequently than it should. I checked the power settings and minimum processor state was 100%. I changed it to a more reasonable number and all was good. But 10-15 minutes later the fan would come back on full blast because that setting has been reverted back to 100%! Every time I reset it, some time later it go back to 100%. I'm not one to leave something like that alone and after a lot of searching the internet and applying updates I found that someone else had discovered the cause. The stock trackpad driver was responsible for constantly changing that power setting!! I found a different version for another laptop and that fixed it. But just imagine how many people that own this exact laptop and it's always hot and gets terrible battery life. All that power management technology and passive cooling completely wasted because of one driver. |
