Introdução
If your Lenovo ThinkPad E14 Gen 2 is overheating, running loudly, or experiencing performance issues, the heat sink may be damaged or not functioning properly. The heat sink works with the cooling fan to draw heat away from the CPU and other key components, helping your laptop maintain safe operating temperatures.
Before replacing the heat sink, check the Lenovo ThinkPad E14 Gen 2 troubleshooting pages to rule out dust buildup or fan issues.
To access the heat sink, you’ll need to remove the back cover and disconnect the fan assembly and related components.
Warning: Always power off your laptop and unplug the charging adapter before starting this repair. Handle thermal paste carefully and reapply a fresh layer when installing the new heat sink to ensure proper cooling.
