What is a potential consequence of improper hardware tinkering?

Improper hardware tinkering can lead to a voided warranty because manufacturers often specify that any unauthorized modifications or repairs to the hardware will nullify the warranty agreement. When users open the device or make changes to its components without following the manufacturer's guidelines, they may inadvertently damage the hardware or use incorrect parts. As a result, the manufacturer may refuse to cover any subsequent repairs or replacements, as the device is no longer considered to be in its original state. This consequence is significant because warranties are designed to protect consumers from potential defects and malfunctions, and tampering with the hardware eliminates that protection.
