Set your multimeter to diode mode. Test the high-side and low-side MOSFETs around the CPU socket for short circuits to ground. : Brands like Compal, Quanta, Wistron, or Foxconn

If the board turns on briefly but immediately shuts off, a secondary power rail (such as the GPU or memory supply line) may be shorted. Use an ohmmeter to check the resistance to ground on all major coils. Low resistance values (excluding the CPU core rail) indicate damaged silicon components or failing decoupling capacitors.

The E89382 marking on a motherboard is a widely recognized UL (Underwriters Laboratories) file number. It trace back to the original board manufacturer, most frequently associated with Foxconn (Hon Hai Precision Industry Co.). This specific marking is found on millions of OEM motherboards used by major brands like Intel, HP, Dell, and Lenovo.
