How often does it happen? Is it an everytime issue or occasional?
Did you try plugging the power from a different socket? Alternately try with a different power cable (borrow from friend to test). Once you have identified whether it's your laptop or cable, take the next steps. If the laptop is in warranty, consult your seller/vendor for services
Replace the inner part of the fan - some unit just slip right out. check on kijiji and find a local computer repair guy that will sell you one for 5 or 10 bucks, or get a broken laptop for 50 to 100 and lots of parts. I had one broken wing and broke on off the other side to even it out... even though one side had 1 extra wing it wasn't that far off balance so vibration should be minimal. if you keep your laptop clean inside around the heat-sink and fan area and put silver heatsink on the gpu and cpu as well as install the manufacturer drivers and update them to cool things down and speed things up and keep things from heating up. One more issue is the charging port and charger end get frayed and or loose and will cause heating issues and have caused fires. Replace batteries that are weak as they are continually charging too much.... Store batteries and at 70% and don't pull them out of the laptop while it's plugged in. Fully charge batteries and fully discharge them between charges. Good to have 2 batteries. Don't use hot batteries especially after charging and don't charge a hot battery.
Get a can of compressed air and blow out the vents on the bottom and side of the laptop. The fan could just be out of balance with dust. It it still makes a noise afterward, the fan itself may be going out and need to be replaced.
you may have inadvertently killed the power module of the laptop. that has happened to me a couple of times, so far, and repair has always been in the hundreds of dollars. I hope that is not the problem in your case. Have you tried using a universal power supply to make sure that your power supply is not the issue? Anyways, the best of luck to you.
