10203-1 La56 Mb 48.4jw06.011 Schematic «Complete ›»

You can often see retailers and repair specialists selling "Lenovo B560 V560 LA56 10203-1 48.4JW06.011" as a single motherboard model for both these laptops.

The code 48.4JW06.011 follows TPV’s document numbering system:

Intel Sandy Bridge (Socket G2 / rPGA988B) Celeron, Pentium, Core i3, i5, and i7 CPUs.

If the KBC and Power rails are good, the BIOS may be corrupted. Use the schematic to identify the BIOS chip and flash it. Scenario C: No Charging 10203-1 la56 mb 48.4jw06.011 schematic

While the exact visual of the schematic is not reproduced here, typical designs with a similar naming convention consist of the following core sections:

Generated by the Always-On power management IC (PWM controller). These rails must be present the moment the charger is plugged in. They power the Embedded Controller (EC/Super I/O) and the power button circuit. Run/System Power Phase

Every major power IC has a PGOOD pin. If a chip successfully regulates its target voltage, it outputs a high signal (usually 3.3V) on this pin. If one PGOOD line is pulled to ground, the Super I/O (EC) will halt the startup sequence. You can often see retailers and repair specialists

The 10203-1 LA56 motherboard is built on a standard Intel-based mobile architecture from the Sandy Bridge/Ivy Bridge era. Understanding how the core chipsets communicate helps isolate faults during the troubleshooting process.

A 4MB or 8MB SPI Flash ROM chip containing the BIOS firmware.

Intel HM57 or HM65 Express Chipset (depending on the exact sub-revision). RAM Support: Dual-channel DDR3 SODIMM. Use the schematic to identify the BIOS chip and flash it

(or LA-56) motherboard is based on the Intel Calpella platform, which supports the first-generation Intel Core i3, i5, and i7 processors.
