motherboard schematic is a technical document for the Dell Latitude 3570

Symptom: Dead TV (No Standby Light)

SoC (System on Chip)

This board uses an design, meaning the CPU and PCH are integrated into a single BGA chip (usually marked as "Intel Bay Trail"). This simplifies the schematic compared to older boards that had separate Northbridge and Southbridge chips.

Component Highlight: The Optocoupler

Note:

The schematic presented here is a generic reference based on the most common revision (Rev A). Some manufacturers may ship slightly altered layouts (e.g., different MOSFET part numbers). Always verify part markings on the physical board before performing any modifications.

Check the DC-in jack and the first two protection MOSFETs (labeled 'Q' on the board). Always-On Rails: Ensure the +3.3V and +5V "Always" voltages are present. KBC/EC Power:
