Provides Lenovo V560 BIOS and EC dumps for firmware-related repairs.
For component-level repair technicians, having access to the schematic diagram is essential for troubleshooting common board faults like "no power," "power but no display," and "liquid damage." 1. Board Overview and Specifications A schematic with this naming convention typically contains
| Sheet No. | Content | |-----------|---------| | 1 | Block diagram, connector pinout (CN1, CN2) | | 2 | LVDS receiver & T-Con input conditioning | | 3 | T-Con main IC (LA56) with crystal 27MHz/48MHz | | 4 | Gamma buffer (P-Gamma IC) – e.g., BUF16821 | | 5 | VCOM amplifier & temperature compensation | | 6 | DC-DC boost + charge pump (for VGH/VGL) | | 7 | Gate driver outputs (CN3, CN4 to panel) | | 8 | Source driver outputs (mini-LVDS channels) | | 9 | BOM (Bill of Materials) + test points |
Check for "Standby" (3.3V/5V) voltages. A common failure point is the PU4103 or PU4104 regulators. For component-level repair technicians, having access to the
Controlled by a dedicated PWM controller IC (often an RT8205 or similar). These rails power the Super I/O (EC) and the BIOS chip immediately when power is connected.
