 "markdown": "# HP EliteBook 840 G6 heat sink assembly replacement\n\nSource: https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf (printed pages 39–53). OEM-documented procedure; not bench-tested.\n\nThis guide covers replacing the heat sink assembly in the HP EliteBook 840 G6 Notebook PC. HP's Table 6-2 on printed page 51 lists the spare part numbers for the discrete and UMA graphics-memory variants.\n\n## Tools and parts\n\n- Pry tool (non-conductive, non-marking), magnetic Phillips P1 screwdriver, and Torx T8 screwdriver.\n- Static-safe work surface\n- `L62751-001` - Heat sink assembly for models with discrete graphics memory. Source: printed page 51.\n- `L62740-001` - Heat sink assembly for models with UMA graphics memory. Source: printed page 51.\n\n## Preparation\n\nHP's preliminary requirements on printed page 32 set out the tools needed for removal and replacement work along with the service cautions that go with them. Follow the preparation steps on printed page 37: shut the computer down, pull the power cord out of the machine, and detach external devices; the bottom cover procedure on printed page 37 comes after that. Removed subassemblies and their screws belong away from the work area, plastic parts should not be forced, and cables are handled by their connectors and routed clear of the parts being lifted out (printed page 32). For this procedure the battery cable on printed page 49 has to come off the system board before the heat sink is handled.\n\n## Replacement\n\n1. Get the computer ready for disassembly before any cover is lifted (printed page 39).\n2. Take the bottom cover off the chassis so the interior is exposed (printed page 39).\n3. Unplug the battery cable from the system board (printed page 39).\n4. If the model has discrete graphics memory, work the six captive screws loose in the sequence stamped on the heat sink and lift the heat sink off the system board (printed pages 51, and 51).\n5. Scrub the old thermal material off the heat sink and the system board surfaces and use the replacement thermal material supplied with the spare part kits (printed pages 52, and 51).\n6. If the model has UMA graphics memory, work the four captive screws loose in the sequence stamped on the heat sink and lift the heat sink off the system board (printed pages 53, and 53).\n7. Install the heat sink by reversing the removal steps, seating it on the system board and tightening the captive screws in reverse of the stamped sequence (printed page 53).\n\n",
