How to tips:
1. You need to remove all screws securing the bottom cover and remove the cover to access the heat sink and cooling fan assembly.
2. Please disconnect the battery connector from the motherboard before you touch any internal hardware. Otherwise, it may short circuit and damage your laptop.
3. You don't need to apply for new thermal grease for the processor because our heatsink already comes with thermal grease.
