Troubleshooting the problem:

My laptop started to have this problem about 1 year ago after i sugest to clean my laptop.

Before i have tryed many things, disascemble the fan and change termal paste, clean the radiator but it was not so dusty, because my laptop always in the same place it is clean and flat place. I have updated bios it does not gave any changes.

I have try every thing downgrade BIOS update it again, reinstall Windows 7 install Win 10. Try all drivers from the link:

Solution:

Then two days ago i was checking the internet to solve it in russian content in the internet, i have meet some people with the same problem but no solution people just say: "it is impossible pc fan motor have + and - you can reverse it only if you have change the polarity".

I was feed up with this problem and almost give up. Then i have restart the laptop and blow into my laptop radiator wholes))) with my mouth, fan stop for 1 second and start to blow again, but this time it started to blow from the notebook with hot air) True story!

So if you all people have problem with reverse blowing fan(into the laptop) Just blow into the laptop with your mouth))
