Hey all, I had an overheating issue where I would get "forced hibernation". The BIOS was set to "always on" and the fan made no sound and rarely felt like it was blowing. I got on with HP chat support and they sent me to this link. http://h10025.www1.hp.com/ewfrf/wc/...lc=en&cc=us&product=4121373&os=4063〈=en This appears to have fixed the issue. Now my fan makes noise and is blowing a wee bit all the time. Hope this helps some of you. It looks like a rollback, as the bios is the same number but the version I had was "5" and the new one was "4".
