I agree with jipsonnj. Once I opened up the CPU of my home computer to fix a problem. Unfortunately, I could not fix it up, and later had to call the technical person from the concerned company. First thing the man asked was whether I tore the warranty sticker and I had to pay some bucks for the replacment of a bit of wire which caused all the problem. If I had not opened the CPU in my haste, I need not not have paid a single penny. A good lesson
