There are big "no trespassing" signs affixed to most of our electronics.
If you own a gaming console, laptop, or computer, it's likely you've seen one of these warnings in the form of a sticker placed over a screw or a seam:
"Warranty void if removed." In addition, big manufacturers such as Sony, Microsoft, and Apple explicitly note or imply in their official agreements that their year-long manufacturer warranties -- which entitle you to a replacement or repair if your device is defective -- are void if consumers attempt to repair their gadgets or take them to a third party repair professional.
these stickers and clauses are illegal under a federal law passed in 1975 called the Magnuson-Moss Warranty Act.
