Around the internet there are loads of guides on how you may ground yourself when fixing a Laptop/Desktop PC. However there is too less information on why it is actually done. My concern is why do it in the first place if there is no big problem? Is it harmful for us or for the PC. I have never seen a PC fixer in Pakistan grounding himself when fixing a PC.
Is this like one of those stupid precautions that only the developed nations practice because they have ample time and resources.
