Do what you've been doing in your cleaning methods. I would suggest you don't mention this if the "warranty issue" ever comes up. Obviously use common sense here.
Just bought a Dell desktop--first time trying Dell.
I was shocked to see that if I open the case, my warranty is invalid.
Typically, I dust inside the case every 2-3 months, and that is necessary because I find a lot of dust that poses a fire hazard, etc. I have a bracelet that grounds me to the case to avoid static problems.
With the Dell warranty, do I have to pay a licensed technician to clean dust out of the case several times this year?
Thanks for any advice ...
