Why is my laptop cpu fan stopped working completely then worked back again?

post #1 of 3
Thread Starter 
It's not like normal fan working when computer gets cooler stops, when it's heating up starts working. It happened 7 days ago. And that never happened since then. But I'm still wondering why it's happened. My laptop is just a few days old. I was checking my air vent and suspiciously was being silent. After keep checking 5 to 10 min the fan still wasn't not working. And then I started running heavy software like video converting program. CPU was working 100% when I load this, fan still was not working laptop bottom was getting heated up. Then decided to check my cpu temp and installed everest ultimate edition. Everest doesn't recognize both cpu temp and fan. I restarted laptop because my laptop was getting hotter. And when I restart it, laptop fan started working normally. CPU temp, fan speed are recognized in everest software. After I noticed that in system cooling policy settings was in passive mode on battery. Did it cause this? Is there anyone experienced problem like this before? Why it's happened?

Yes, generally speaking if you're on battery and you switch all functions to save power, then it'll shut off the fans. Mine doesn't do that that the reasons for that are obvious. tongue.gif

Just make sure you're always on 'balanced' if you're running off the battery and 'high performance' when plugged in. smile.gif

My fan is still working just fine regardless of power management. This issue only happened one time. No matter to what settings that I changed in power settings or doing anything for this, problem doesn't appear again.
