No official datasheet for the 671W24H0D02A has been published publicly, but based on community documentation, motherboard photographs, and repair logs from multiple sources, we can reconstruct a fairly accurate picture of the board’s architecture:
Here’s a concise summary for technicians troubleshooting this board:
: These lines show where sensors, buttons, and displays connect. If a specific function (like a button not working) is failing, trace these lines on the diagram to the microcontroller.
Typically integrated with the processor or uses a mobile Intel chipset (e.g., HM70/HM76).
The area around the keyboard connector and the charging circuit is particularly vulnerable on this chassis design. Where to Find the Full Schematic 671w24h0d02a gp schematic full
: Some users report failures in the "bridge" (PCH/Southbridge) which can lead to "no power" or "no display" issues. Voltage Rails : When diagnosing power issues, the schematic's Appendix B
If the board doesn't turn on, the schematic review should focus on the "Power On Sequence" diagram (usually found near the end of the full PDF), checking if the RSMRST# signal is released by the EC.
Another valuable source is Russian-language forums like , where users share extensive repair logs and diagrams for specific models like the "IRU W255BW" that uses the same 6-71-W2400-D03 GP motherboard.
Component-level troubleshooting relies on understanding how power flows through the system. The power architecture on this Clevo motherboard transforms the high-voltage (typically 19V from the AC adapter or 11.1V/14.8V from the battery pack) into specific low-voltage logic rails.

Always cross-reference the revision number printed physically on your motherboard PCB with the schematic text block. This ensures that any component variations or factory engineering changes match your specific board version.
: Look for burnt tracks, leaking capacitors, or soot around the transformer.
Additionally, the following community platforms have references to the schematic:
Locate the DC-In jack area and verify the voltage at the first and second isolation MOSFETs. Ensure that the charger IC (often an Intersil or Texas Instruments variant) is generating the ACIN signal to notify the EC that an adapter is present. The area around the keyboard connector and the
, a major Taiwanese original design manufacturer (ODM). While Clevo does not sell directly to consumers, their motherboards are the foundation for laptops sold under various "rebranders" such as (specifically models like the W270HUQ). Architecture and Components The 6-71-W24H0-D02A GP is built around the Intel Sandy Bridge
If your goal is to repair a dead Itautec Infoway W7535, your most efficient path forward is:
Locate the input protection MOSFETs immediately following the DC-in jack. Check if VIN passes through the entry dual-MOSFET configuration. If the gate voltage is missing, trace back to the charging IC to check for short circuits on the ceramic decoupling capacitors. 2. Corrupt BIOS or Missing EC Communication
Measure the resistance across the DC output rails to ground to ensure there are no short circuits on the load side. Step 3: Hot Circuit Testing (Live Power)
