Chip level means removing components. A practical guide lists: laptop motherboard chip level repair guide pdf

• Diagnosing and replacing surface-mount ICs (integrated circuits) like Power Management Chips (MAXIM, Texas Instruments).
• Re-balling or reflowing BGA chips (PCH, CPU, GPU).
• Tracing signals through multiple layers of the PCB using oscilloscopes and logic analyzers.
• Repairing broken traces under chips without a schematic.
• Flashing and reprogramming BIOS/EC chips.

Lead-Leaded Solder: When replacing components, mix original lead-free solder with leaded solder to lower the melting point and make the job easier. Conclusion Lead-Leaded Solder: When replacing components

5. Troubleshooting Flowcharts

• Decision trees: "If no 3V/5V → check EN pin of TPS51225 → if low, trace SLP_S3# from PCH."
• Voltage measurement points table.
