New to this forum and received my GTR5 5900hx in december. Due to making a change in the bios that the PC didn't like it would not boot so I had to reset the cmos. I wanted to set the performance mode to 45w but when I do it will not boot. If I leave it in auto it works fine. Anyone run into this or have a sugggestion? I am pretty sure I set it to 45w in the past.
