HP EliteBook 8530w Heatsink Replacement

はじめに

If your computer is experiencing random shutdowns, excessive heat, glitching, or frequent crashes, especially during compute-intensive tasks, it may be due to an overheating CPU. The CPU relies on the heatsink and fan to regulate the temperature, but the interface between the CPU, the thermal paste, can become old and brittle, losing its thermal conductivity. This prevents the necessary amount of heat from leaving the CPU, which can cause issues like those listed above. Since the heatsink is simply a piece of conductive metal, it’s unlikely for this part to fail, but cleaning and reapplying the thermal paste can potentially address these problems. This guide will show you how to remove the heatsink in an HP EliteBook 8530w laptop.

For information on how to clean and reapply the thermal paste, see this Thermal Paste Application Guide.
