HP ProBook 640 G3 Overheating

Obstruction of air intake or exhaust can cause a buildup of heat within the system, slowing performance, and eventually causing failure of the device.

• Take note of the fan grates on the sides and bottom of the laptop, ensure these are not being obstructed by an outside object. Obstructions could include walls, pillows, blankets, etc.
• Listen to the sound the fan makes, if it’s abnormal, skittering or stuttering, this could suggest damage to the cooling fan properly

Buildup of dust or other forms of detritus can contribute to inefficacy in the laptop's cooling system, leading to overheating.

• Find the vents through which the laptop intakes and exhausts the air. If you’re struggling to find them, try to feel where there is a small sucking sensation or a greater amount of heat than normal.
• Check the vents for an excessive amount of dust or other materials within the vents. Liberal application of compressed air to the affected area should be able to remove the blockage.

A computer battery can last for a long time and can always be recharged, but its physical power degrades over a long period of time. An older battery will need to use more power to maintain necessary power levels, which in turn creates more heat than necessary and more pressure on the system. Replacing a system’s battery is a standard process that can help it from overheating.

• If you notice a distinct decrease in battery life or a significant jump in performance when the device is plugged in, a replacement may be in order.
