My aunt messaged me asking if I could help figure out what was wrong with her laptop, she sent a video of the sound, it sounds like basketball shoes stopping on the court, any help at all is very much appreciated!
Definitely the sound of a dying fan motor. The only way to fix this is to replace the fan. It's not far from full failure which will result in a shutdown due to overheating. As above, if this was issued by her employer then the IT department is responsible for service/repair/replacement.
