Fan and overheating repair on the HP EliteBook 840 G3

The HP EliteBook 840 G3 cools itself through a small fan and heatsink that collect dust over time. We clean the whole cooling path and replace the thermal paste, and the fan itself if it's worn.

What we do

We strip the cooling system, clean the heatsink and fan, and replace the thermal paste on the processor and graphics chip. A worn or noisy fan is replaced.

Doing this early prevents the heat damage that leads to graphics chip and motherboard failures.

How long it takes. Usually done the same day.
