imarios Posted January 11, 2015 Share Posted January 11, 2015 I have an HP G7000 laptop running Lion 10.7.5 . My fan is not working properly. It's in stand-by until the laptop gets really hot, then it start very loud for about 30-40 seconds or less. When I start the laptop, in Bios settings, it works smooth. At the Apple boot logo it stops. I had deleted the NullCPUPowerManagement kext. Link to comment Share on other sites More sharing options...
