We explain what to do if you have an overheating laptop
Laptops are more prone to overheating than Desktop Computers due to their design, it goes without saying that almost every laptop will suffer from this in it’s lifetime of you owning it.
At Computer Repair & Care we strongly believe if you look after your computer it will look after you, some things are totally out of your control when it comes to electronic devices but like anything computers need servicing just like cars do if you want them to run well.
Keep IT Cool
During the course of our repairs we come across this problem a lot, more so with Laptops due to their slim design and lack of fans.
Laptops over time tend to become blocked up with dust and pet hair, by design the fans will attract this dust and over time we have seen this totally block the vents on the side of the laptop creating a layer of dust which prevents the laptop from blowing out the heat generated from the processor and graphics chip.
If the fan vents are blocked then this means that the heat is circulated inside the laptops casing which will then cause your laptop to overheat, your laptops motherboard and attached components will run much hotter than the intended manufacturers specifications, in turn this can cause failure of other components and also cause graphics chip related issues due to the heat.
We have also noticed that more so on laptops that hard drives can be affected by high temperatures, with hard drives storing your operating system and important files it is strongly advisable not to overlook your laptop overheating.
We often compare servicing your computer to a car, if your car was overheating you would not ignore it would you? it would be taken in for a service to prevent damage to your engine, if your laptop needs to be serviced then don’t ignore it before it costs you more or possibly damages your laptop beyond repair.
If you notice a error on the screen informing you of a system cooling error or if your laptop gets very hot and closes down between 5-30 minutes or so then this is a sure sign of an overheating laptop.
When laptops get really clogged with dust inside the fan it can block the fan blades and prevent them from spinning to cool the laptop, if you don’t hear your fan spinning then it has become blocked and will need a service ASAP.
Servicing an overheating laptop requires the laptop to be fully stripped down, often resulting in the motherboard being removed and the fan assembly being cleared off dust and the fan vents being unblocked of dust.
Most fans on laptops are sealed so they need taking apart to clean fully, whilst cleaning the fan we will reapply thermal compound to the CPU (Processor) and heat sink to aid the efficiency of heat transfer, over time the thermal compound applied at the factory dries out and becomes less efficient.
Laptops often start to have overheating issues when approx 2 years old but is not uncommon in laptops that are just over a year old, the advice is to get your laptop serviced sooner rather than later.
How to prevent a laptop from overheating
There are a few things you can do to prevent the onset of a laptop overheating, this is not to say it will fully prevent your laptop from ever overheating again.
Try to keep laptops on a flat level service, a table or desk is best.
Avoid putting your laptop on carpets as carpets hold more dust, pet hair and other debris that is not good for laptops.
Avoid putting laptops on your bedroom duvet, putting your laptop on your duvet is not a solid service and you will block the vents and in turn any heat trying to escape will circulate inside the laptop which will cause it to overheat very quickly.
Some people use a laptop cooling pad which has built in fans, this certainly won’t do any harm.
Avoid putting your laptop on your lap, even more so if your laptop gets hot in the first place.
