How Our Technicians Complete Your Repair
Rear Casing Teardown & Battery Isolation
Technicians extract chassis screws, release perimeter clips, and immediately sever the main lithium-ion battery connector.
Vapor Chamber Disassembly & Fin Cleansing
The heatsink is removed, and high-pressure compressed air dislodges thick dust mats blocking the copper radiator channels.
PTM7950 Phase-Change Pad Application
Dried thermal paste is removed using chemical solvent, and factory-spec PTM7950 pads are cut and applied to CPU and GPU dies.
Thermal Stress Benchmark & Verification
We reassemble the laptop and run 20-minute FurMark and Cinebench stress tests to confirm sub-80C temperatures and whisper-quiet fans.
