How do I replace the front power switch cable?

Recently, I have been experiencing issues with my computer’s power button. Every time I press it, either the computer fails to turn on or I have to press the button multiple times to get it to work. I suspect the front power switch cable might be worn out or damaged. I have limited experience with computer hardware and find the idea of opening up my computer a bit intimidating. I understand that the front power switch is crucial for powering the computer on and off, and I don’t want to cause any further damage or risk harming other components. What I need is a clear and detailed guide on how to replace the front power switch cable. Specifically, I am looking for step-by-step instructions that can walk me through the process, explaining the tools I might need, and any precautions I should take. How can I ensure I correctly identify the cable and reattach it properly without causing any additional problems?
