: Identify the charging controller circuit to see if the battery is receiving the correct voltage.

: Use the schematic to trace the 19V rail (B+) from the DC jack to the charging IC and main power MOSFETs.

: If the laptop powers on but has no screen output, the diagram helps check the LVDS/EDP connector voltages (typically 3.3V and 19V for the backlight).

Because motherboards like these are proprietary, official schematics are not typically released to the public. However, several specialized technician repositories host these files for professional use:

: Technicians use the schematic alongside a multimeter to find shorted capacitors on the 3.3V or 5V "Always-On" rails.

: Offers the schematic in PDF format specifically for the E4325 and M495 models.

The is a motherboard widely used in budget-friendly Lenovo laptops, specifically the Lenovo Essential E4325 and Lenovo M495 . If you are a technician or a DIY enthusiast looking to repair power issues, backlight failures, or charging problems, having the schematic is essential for tracing circuits and identifying faulty components like MOSFETs or ICs.
