Explanation
When a power supply short is suspected, personal safety is the absolute first priority. Disconnecting power eliminates the risk of electric shock or further damage before any other action is taken. An ESD strap, grounded workbench, and ESD mat are all important for protecting components from electrostatic discharge, but they are secondary concerns - none of them protect the technician from a live electrical short. Always de-energize the system before beginning any hardware servicing.
