My right fan
20 - 30 minuten
I was laying on the couch one night when I heard this horrendous noise. I thought it was my air conditioner, but it turned out it was coming from the upper right corner of my laptop. I instantly knew what it was.
Smooth as butter. I used the guide to disassemble it before I even ordered the part. When it arrived, it was a 7 minute installation and reassembly.
Don't perform this repair in a room with a carpet.
