Laptops are prone to overheating, especially when they are used on soft surfaces like beds or couches. There are a few things you can do to prevent your laptop from overheating.
First, make sure that the vents on the bottom of the laptop are not blocked. Second, use a cooling pad designed for laptops to help wick away heat. Third, avoid using your laptop on soft surfaces and in hot environments.
If your laptop does overheat, turn it off immediately and let it cool down before continuing to use it. Be sure to keep an eye on the temperature of your laptop and take breaks if it starts to feel warm.
Laptops are increasingly becoming a staple in households across the globe. However, as laptops grow in popularity, so does the problem of overheating. Fortunately, there are a few things users can do to prevent their laptops from overheating.
The first step is to make sure the laptop is being used in a well-ventilated area. If the laptop is being used on a bed or couch, for example, there is a chance that the laptop will overheat because the ventilation vents on the bottom of the laptop will be blocked.
Another way to help prevent overheating is to clean the laptop regularly. Over time, dust and dirt can build up on the laptop’s fan, which can cause the fan to work less efficiently and cause the laptop to overheat.
There are also a few things users can do to the settings on their laptop to help prevent overheating. One is to lower the screen brightness. A brighter screen requires more power and generates more heat.
Another setting that can be adjusted is the power settings. Many laptops have a power-saving mode that can help lower the amount of heat the laptop produces.
Finally, there are a few different types of laptop cooling pads that can be used to help prevent overheating
The cooling of the CPU referred to as the chip or the laymen, the brain of the laptop is a dilemma that most manufacturers have to face when designing a laptop casing and choosing the right or correct CPU for it. The cooling is normally performed by the fan and some kind of metal conductors such as aluminum or copper called a heat sink.
In addition, the CPU and lately the GPU are connected to the metal heat sink via the thermal grease or compound. So, this grease conducts heat but not electricity. Although, the trick for the manufacturers is to get rid of as much heat as possible using a small fan and a heat sink as the CPU will allow vents to cut into the casing which allows the fan to suck cool air from the bottom and force it over the heat sink and blow it out the side or rear thus cooling the CPU and the GPU as well.
In modern times copper is being used as the conducting metal and liquid is pumped through the system and radiators and exhaust ports are used just like in motor vehicles. All this to get rid of the heat and make the system much faster or quicker.
The problem is that over time dust and other particles clog the vents, fan, and exhaust ports or radiators of the system, thus restricting airflow and cooling as well. This’s fixed relatively easily by blowing out the vents and fan with air and using a brush or earbud to clean away the dust.
Remember that, in the computer world, dust destroys! there’s however another hidden problem that occurs when computers or laptops heat up or overheat. They tend to dry out the thermal compound that conducts the heat, thus causing the system to overheat quicker or faster.
Luckily, most CPU, GPUs, and chip manufacturers have built-in protection for this and they step down the OS operating system bit by bit until they eventually switch off the CPU and thus the system shut down. So, if you have a computer system that starts working slower and slower and then switches off for no apparent reason and overheating could be your problem.
To solve the overheating problem especially in laptops, I’m going to show you how to get to the cooling unit, dust it out, and replace the thermal grease and put everything together again.
In order to demonstrate this, I’ll be using a friend LG F1 pro express dual laptop that started exhibiting just the symptoms. It’d become sluggish and then suddenly switch off for no reason. Although, This caused him a lot of lost work and a corrupted outlook PST email file.
Here I’ll show you step by step the solution to this nasty problem.
Preparing for the process:
Before you start, make sure that you’ve made a backup of all your data files, and if in the unlikely event that something does go wrong, you’ll be able to restore your application programs and the data as well.
Also, make sure that the backup is totally separate from your laptop not on the same hard drive and on an external device like the SD card or USB or portable drive respectively.
Prepare an area to work on that is well lit, clean, dry, and has enough space. You can use a towel and soft cloth under the laptop to protect it because it’ll be lying on its screen for most of the time during the procedure and make sure that nothing you use, and even your clothes, and generate static electricity. However, this process will take roundabout 30-minutes.
- A holder to keep the screw from getting lost or hidden anywhere.
- Thermal grease and compound. Your local computer or PC shop and hardware store should have this, otherwise, Google is your friend.
- Screwdrivers that exactly fit the screw on the back of your specific laptop.
- Earbud cotton swabs
- Wooden tongue depressor and any other soft object to strap the old thermal grease off.
- Brush as well
Removing the battery and back cover:
After you’ve backed up all your data files and shut down your laptop, unplug the power source and remove the battery respectively. In the case, LG FI pro expresses dual the battery is released by 2 clips.
Although, the system door has four screws that give you access to the central processing unit, graphics cards, and RAM memory, and various other parts like real-time clock battery, modem, and cooling unit as well.
Moreover, release the battery and remove it completely. Using, the correct screwdriver loosens the four screws. Also, place them in the holder, once they’re removed and remove the back cover as well and set it aside. You’ll notice dust clinging to the back cover and use the brush and earbuds to clean the vents and back cover as well.
Unscrew and remove the cooling unit:
You can now put on your rubber gloves and attach your grounding or earthing strap if you want to. I didn’t.
In addition, the easiest way to cooling down the unit is to look for the fan. Once, you have this, then it should locate the screw holding it down and carefully remove them and place them in the holder.
Gently grip the cooling unit and remove it from the laptop or computer. try twisting it back and forth, left and right, and slightly before lifting it out. It’d break any hardened thermal grease that acts as glue. This one comes out at only one angle.
So, you remove it slowly and gently, because the fan power cable Is still attached to the motherboards and needs to be removed before the CPU will come out completely.
Dust out the unit:
Using your breath, compressed air, hairdryer and fan gently blow out the dust located in the fan, case, exhaust port, and anywhere else you see it accumulated and you can also use earbuds to clean the fan blades as well.
Moreover, hold the fan down, when blowing it with air, so that it doesn’t operate in the reverse direction and also not work against the blowing air. Additionally, Use the brush to dust everything off one last time before it out with the air again.
However, using a soft object like a wooden tongue depressor and plastic knife or old credit card scrape the old thermal grease or compound from the CPU, GPU, and heat exchanger. Be gentle and take your time as there’s no rush and trying different angles and the dried thermal grease should just flake off.
Here, you’d also use the isopropyl alcohol wipes and an earbud dipped in isopropyl alcohol to remove the dried thermal grease. It comes off easier then, if you’re going to work and touch components on the motherboard, then I suggest you wear an earth or grounding strap and rubber gloves as well.
Apply new thermal grease:
Place a very small blob of thermal grease on the CPU and GPU only. Don’t place any on the heat exchanger and you only need to place thermal grease on one and another. Use the wooden depressor and plastic knife or an old credit card to spread it evenly and very thinly over the surface of the area of the CPU or GPU and heat exchanger that will come in contact with each other.
More isn’t better in this case and too much thermal grease will not cause better heat conduction, but might even cause some heat build-up.
Frequently Asked Questions:
How can I cool down a laptop?
- Do not block your computer vents
- Use a laptop cooling pad
- Avoid using programs that push your computer or PC CPU limits
- Clean your computer or PC fans and vents
- Change your PC setting to improve its performance
- Shut down the computer or PC
Why does my laptop overheat?
Some causes of overheating are damaged or malfunctioning fans are due to the dirt and grime clogging up the fan and preventing it from rotating properly.
Furthermore, block air vents that prevent air from flowing into the laptop and running too many software programs in the background can cause your processor or CPU and fans to go on overdrive.
Can overheat kill a laptop?
If the internal temperature stays too warm for a long time, then you may experience performance issues, errors, and premature hardware failure as well.
My answer is yes. Overheating can kill a laptop. When a laptop is in a safe and clean environment like an Office, then overheating is not much of an issue.
What happens if the laptop overheats?
A laptop that fully overheats causes damage to the internal components. Before, this happens, the laptop should attempt to shut itself down and if you smell smoke, a burning odor, and the fans never run or the fan runs all the time, then be careful to avoid running your laptop.
Is a laptop supposed to get hot?
This’s normal and it’s simply the part of the way that the computer cools itself. However, if your computer or PC gets very warm, then it’d be a sign that it is overheating which can potentially cause damage. Most laptops get reasonably warm once you’ve been them for a while.
Are laptop cooling pads worth the money?
If your laptop is suffering from heart problems, then laptop cooling pads are a much cheaper and effective way to solve your problems. While, they are not the ultimate solution, but they can resurrect a failing device for less than the cost of a single PC game.
