My laptop screen says fan error, but i don't want to replace it or take it apart

I am a kid so don't tell me to buy stuff or take it apart i just want to fool the laptop for enough time for me to reboot it. also i had it for 6 years don't tell me to buy a new laptop either. Also flashes black then normal. first time had that problem. fan error had that problem for a while never rebooted after i manged to turn it on. Using my friend laptop right now

 

If you don't want anyone to tell you how to fix the problem, then what are you doing posting here?

 

i want people to teach me but not really expensive ways okay?
