Check if the IC receives 19V at its VIN pin. Then, check the Enable pins (EN or EN0). If Enable is missing, trace it back to the Super I/O chip.

The Nuvoton Super I/O chip interacts directly with the SPI Flash ROM (BIOS chip). If the laptop turns on but displays a blank screen with a spinning fan, or if it won't trigger the power sequence despite having proper 3.3V/5V rails, firmware corruption is highly likely.

Measure the inductors (coils) for +3.3V_ALW and +5V_ALW . If these are absent, verify if the PWM controller chip is receiving its main enablement signal ( EN or SHDN ). Troubleshooting a "No Display" or "No POST" Condition

To repair a dead board, study these specific schematic nodes: 10203-1 la56 mb 48.4jw06.011 schematic

Identifies the PWM controllers, MOSFETs, and inductors for the core voltage.

Relies entirely on Intel HD Graphics integrated into the CPU.

motherboard is a staple component in Lenovo B560 and V560 laptop series, known for its Wistron LA-56 platform design. For technicians, engineers, and DIYers looking to repair this specific board, obtaining the correct schematic diagram and boardview is crucial for troubleshooting power, display, or component-level failures. Check if the IC receives 19V at its VIN pin

These are located near the DC-in jack. Test for continuity:

The Super I/O chip ( NPCE791 ) manages this sequence. It releases signals like PM_SLP_S3# and PM_SLP_S4# to wake up the RAM voltage (+1.5V) and CPU core voltage (+VCC_CORE).

The is a motherboard primarily used in Lenovo B560 and Lenovo V560 laptop models. The most useful feature of its schematic is the detailed Power Sequencing and Management section, which is critical for diagnosing "No Power" or "No Display" issues common in these older models.
