This article describes a common overheating laptop scenario along with a fix that works. ![]() ![]() ![]() Overheating laptop and related shutdown problems are very common in notebook computers, especially in home use. At the far end of this copper heatsink, the heat is fed into a series of side- by- side metal fins. This grill provides a very large surface area for the heat to be spread over. A fan then draws air from the outside world and blows across the hot grill, back towards the outside. As it does so, the air picks up heat from the hot metal fins and takes it away from the laptop. In an laptop overheating due to an airflow obstruction scenario, the most likely culprit is a build- up of material in front of the metal heatsink grill. The fan will be drawing in cool air from the outside world through vents in the bottom or sides of the laptop and occasionally there might be a tiny piece of fluff, hair or dust sucked in with the cool air. ![]() When this air is being blown across the hot metal grill, the airborne material can get stuck on the front of the metal fins if it is large enough. If this keeps happening over time, gradually more and more material will build up on the front of the grill, creating an obstruction. A common example of this buildup of material is shown in the image to the left. With less physical space for the air to get through, the air is not picking up heat from the whole set of fins. So a smaller amount of heat is transferred to the air in it’s journey to the outside world. ![]() With less heat being removed, the heat starts to build up inside the laptop (overheating). Temperature sensors detect this and will react by making the fan spin faster and faster. ![]() The point of spinning the fan faster is to force more air through the available gaps, and past the hot metal fins to pick up more heat. This compensation of spinning the fan faster can work to an extent, but eventually a limit will be reached. If the heatsink grill is sufficiently blocked, the fan will be spinning at maximum speed and it will no longer be possible to reduce, or even stabilse, the internal temperature of the laptop. Temperature sensors will realise this and as a final failsafe protection measure the laptop will power itself off. The hope behind this is that if the CPU is no longer producing more and more heat, the existing internal heat will gradually dissipate of it’s own accord and the laptop will, hopefully, avoid serious damage. To fix this problem, you need to strip the laptop down to allow access to the heatsink and fan(s). I’m not going to explain how to strip down a laptop, step by step, as there are guides elsewhere explaining this in detail, and some manufacturers, for example Dell, even provide Service Manuals on the support pages of their website. In most cases, to disassemble a laptop, all you will need are one or two small screwdrivers. Some laptops require special torx screwdriver heads to remove some of the internal screws, so you will need to investigate this in relation to your particular laptop make and model. The pictures I have taken for this post were from an overheating Dell Vostro 3. It would shut itself off after about 1. ![]() How to Fix a Computer That Won't Turn On What to Do When Your Desktop, Laptop, or Tablet Won't Start Share Pin Email.

Normally you can shutdown your computer one of two ways. The first is to manually shutdown your computer when you leave it. The second is to use the Windows power. Had the same type of problem.After system recovery on a HP computer,it wouldn't take the 92 critical updates after 1 critical update and Windows Genuine validation.

If you are an overclocker, or are just suspecting a memory problem with your computer, you should probably run some memory tests. Rather than spending money, you can.
