A brilliant demonstration really clear and well photographed, only one problem how the !&&* do you get the screws undone mine seem fixed solid

thanks for the demo anyway.

Thanks for this!
My Son and I have just successfully removed, cleaned and replaced the fan in his laptop by following the instructions above.
Great work.
Thank you a lot !!!!
I think i did something wrong? I completed all the steps but my fan (which is brand new) keeps making this scary loud wizzy noise instead of a hum and did i not tightem the screws enough or they to tight?? Please help!
Please ensure the fan metal case is not bent and ensure the fan is properly mounted. If this doesn’t solve your problem, your new fan is defective.
