I have a Dell computer security three years. If they open it, then I can cancel the warranty. How do I clean the dust if you can not open?
What model do you have? Go to www.dell.com and find your model and look at the manual for this, you will be informed how to open the case. No guarantee is canceled, DELL is no way to know!
