Thank you. It was quite a coincidence that I found this because I had just purchased that fix it repair tool kit. It was pretty handy that I had it all right here in front of me. Thanks again you made it easy.
Hi @martilynn, thank you for sharing your experience! We're glad that the guide was useful for your repair.
Very helpful guide! Managed to figure out how to clear some gunk off an end users mouse. Much appreciated!
Actually not necessary to remove the interconnect cable, and I wish I had not. Instructions do not include reassembly.
