The Dell Inspiron 13 5320 is a thin-and-light model using USB-C PD charging, which makes it vulnerable to power IC failure due to improper adapters or power surges.
Common symptoms include no charging, failure to power on, no indicator lights, or shutdowns immediately after connecting the charger.
Technicians diagnose by measuring voltage rails and identify the faulty IC—typically a USB-C controller, voltage regulator, or main power IC—and replace it with a matched component.
The IC is soldered using precision hot-air rework stations, ensuring nearby components and PCB layers are not damaged.
After repair, the system is tested for charging current, power draw, and stability before being returned to the customer.
