Toshiba Satellite L300-04P (PSLB8C-04P01X) CPU Thermal Paste Replacement
Introduction
Passez à l'étape 1This guide will show you how to replace the CPU thermal paste in a Toshiba Satellite L300-04P (PSLB8C-04P01X) laptop. The thermal paste is an important compound found between the CPU and CPU cooling system, responsible for conducting the heat from the CPU to the CPU cooler. The thermal paste bridges the microscopic gap between the CPU die and CPU cooler heatsink surface, maintaining thermal conductivity. Old or degraded thermal paste will reduce thermal conductivity, resulting in higher CPU temperatures and increased thermal stress.
Before beginning, ensure the device is powered off and unplugged. Please familiarize yourself on how to clean and apply new thermal paste as required in steps 26 and 27. Additionally, it is recommended to use an anti static wrist strap to prevent damage from static electricity.
Note that there are other variants of this device, varying in processor and memory configurations with model specific codes (PSLB0x, PSLB1x, PSLB2x, and PSLB3x). For those variants, the internal hardware may vary from the model shown in this guide.
