Lac701p Rev 10 Boardview Patched
A corrupted BIOS is another common culprit. You can check the BIOS SPI flash chip (usually an 8-pin chip near the KBC) using a multimeter to verify basic connections. The final step would be to use a programmer to flash a verified, known-good BIOS dump for this exact motherboard model.
Requires flashing the main BIOS IC and EC (Embedded Controller) chip.
The LA-C701P motherboard powers several popular HP 15-series laptops running Intel Broadwell ULV processors and DDR3L RAM. These boards are highly susceptible to: lac701p rev 10 boardview patched
Integrated Intel HD Graphics or optional AMD Radeon dedicated GPU
Technicians frequently use the LA-C701P boardview and schematic to address several recurring issues: A corrupted BIOS is another common culprit
When a pad corrodes completely away, you lose the trace path. By clicking the damaged pad in the patched boardview, you can see exactly where that trace was supposed to go. You can then easily solder a micro-jumper wire from a nearby component or via to restore continuity. 5. Technical Summary and Pin Mapping Tips Target Component Crucial Test Point/Component to Locate PU301 Charging / B+ Rail Control Check ACIN and REGN voltages on nearby caps PU501 / PU502 3.3V / 5V Buck Converters Verify Enable ( EN ) signals from the EC PJ301 / PJ501 Solder Jumpers Isolate specific voltage rails by cutting these U2 Check Pin 8 for +3V_SPI supply voltage
If you want, I can produce a diff of the boardview layer-by-layer or generate an updated BOM highlighting changed line items. Requires flashing the main BIOS IC and EC
The original REV 10 had a notorious error: it swapped the locations of and PU402 (System FET switch) . The patched version corrects this. On the bench, probing the correct ISL9238 charger IC was finally possible without cross-referencing the schematic every two minutes.
Boardview formats evolve, and new file types appear as manufacturers change their CAD workflows. Regularly update OpenBoardView to ensure compatibility with the latest file revisions. The software is under active development, with ongoing improvements to format parsing and performance.
Before using any boardview file, you need appropriate viewing software. Multiple options exist, each with different format support:
Highlights all interconnected points (nets) across the board when a single pin is selected. Why Use a "Patched" Revision 1.0 Boardview?
