Hope everyone is doing all right.
I have a S19j pro and it’s getting a bit dusty, was wondering if there is certain tutorials or sprays to clean it up ? I looked online and most of the things I found useful had a problem (they void the warranty)
I use an electric blower to blow the dust out. Turn off your machine, use the blower to blow through the machine in the opposite direction of its normal airflow. I take mine out to my garage and just fire the dust outside. If you keep after it and do that you should help your machine from it building up too much dust. Hope that helps.
You should be able to remove the fans just remember which way they go. Once removed you can blow thought with dust buster or any of the PC compressed air cleaners.
