How To Fix The Laptop Battery Overheating Issue?
There are a few solutions discussed below in detail. It includes general troubleshooting processes as well as some major changes to the settings. Follow these methods accordingly to remove the overheating issue from your laptop.
Solution 1: Remove Dust And Check The Power Supply
As we have discussed earlier, the main reasons behind overheating are dust clogging up the CPU fans and insufficient cooling. So, the first thing you need to check is dust. If the dust particles are blocking the exhaust ports or making the fans harder to run, the battery gets warmer. Clean the dust using a clean cloth or blow the dust particles out with a can of compressed air.
In case the air vents are clear, check the power cord and the ports. Sometimes faulty or damaged electrical components generate heats and damage the power supply. If you found a tear or any damage, change the power cord or the ports where the power cable gets connected.
There is also a possibility of having some electrical failure in the charger of your laptop. It can turn your laptop overheated when connected to the power supply. Try using a different charger to check if the problem lies in the charger itself.
Found no issue regarding dust or power supply? Then you should check the next solutions below.
Solution 2: Prevent Unnecessary Software To Start Up Automatically
When lots of applications start running in the background when the laptop boots up, the processor generates heat. The temperature rises to excessive amounts as soon as you plug in the laptop with a power source. You need to stop all unnecessary background programs to reduce the excessive temperature of your laptop. What you can do is:
- Prevent software from running automatically when the laptop starts.
- Close its processes when you finish using a program.
- Keep the internet turned off when you don’t need it.
- Try not to play games or play with decreased resolution and graphics settings while charging the laptop.
- If you ever overclocked your laptop, return it to the default value.
Still see your laptop battery getting hot when charging? Don’t worry, there are a few more methods you should check.
Solution 3: Apply Thermal Paste
When there is a lack of thermal paste between the processor and the heat sink, the laptop gets overheated. The thermal paste maintains the heat transfer in CPU to make it cooler. If you notice that the CPU needs thermal paste, you should apply a small amount of fresh thermal paste to the interface between the processor and the heat sink to prevent the overheating.
After applying thermal paste properly, keep eye on the change of temperature of your laptop while charging.
Note: Too much thermal paste can damage your CPU.
Solution 4: Check The Battery
If you keep your laptop always plugged into the power source, but do not use the battery sufficiently, you are probably killing the battery. It will reduce the life span of your laptop battery and might have a problem storing charge or getting overheated while charging.
Once in a while, use the laptop until 20% battery without charging, and then plug it back into the power socket.
You should not keep your battery always connected to the charger. If you find the battery is the reason for overheating, remove it from your laptop and buy a new one.
Solution 5: Use A Laptop Cooling Pad
A laptop cooler provides additional support to cool down your laptop. But you should always remember that buying a proper cooler for your laptop is necessary. A wrong cooler doesn’t work properly to prevent overheating and can make it worse than before.
You need to understand your laptop’s cooling procedure before you buy a cooling pad. Some laptops intake cool air from the bottom. These types of laptops need a vacuum place underneath. If you buy a cooler that gets placed at the bottom of the laptop but doesn’t blow cool air upwards, then it is not going to help you to cool down the processor and your laptop will be overheated much faster.
There are two types of coolers available in the market, active cooler and passive cooler. Active cooler helps your laptop to blow out heated air and to suck cool air. On the other hand, passive coolers just absorb heat without consuming power. So, you should buy a proper one according to your needs.
Solution 6: Change The Power Plan Of Your Laptop
A balance between power consumption and performance is necessary to prevent the overheating issue. Sometimes a laptop gets hot when charging due to higher power consumption when maximizing the system performance.
