The HP ProBook 4540s motherboard uses lead-free solder, which requires higher temperatures to melt. Use high-quality flux and a reliable hot air rework station to avoid lifting delicate copper pads off the PCB. Conclusion
You need the boardview that your board number.
Always disassemble the laptop and locate the silk-screened printed part number on the motherboard itself (e.g., 683493-001 or a platform code like 48.4SI01.011 ). Match your Boardview and schematic downloads strictly to this motherboard code, not just the laptop model number. Essential Tools Required for Motherboard Repair
