Even a laptop that normally works fine may suddenly become slow and its processing speed may drop when it is charging.
This time, we will introduce the causes and solutions for when your laptop becomes sluggish and its processing speed slows down while charging.
What causes your laptop to run slowly and slow down while charging?
Why does the device run slower and become slower while charging?
Some laptops may slow down the CPU when charging to prevent the battery from overheating.
This can cause the entire laptop to slow down significantly (this does not apply to all laptops).
In this case, you may need to change the thermal measures or system settings to prevent overheating.
The problem may also be with the charging cable or adapter.
approach
1. Check if your laptop gets abnormally hot while charging
If your laptop feels unusually hot to the touch, check to see if the CPU fan and other components are working properly.
Also, make sure the air vents are not blocked or that there is no dust in them.
Even if the CPU fan is working properly, it may not be cooling properly.
You may need to reapply CPU grease, especially if you have an older laptop.
CPU grease hardens over time and loses its cooling effect, making it unable to cool properly.
If the CPU is not properly cooled, the entire laptop will run slowly.
Dust from air vents and other areas can be removed easily by attaching a brush-equipped nozzle to the end of your vacuum cleaner and scrubbing the area while sucking it up.
It is difficult for the average person to remove dust from inside a laptop or reapply CPU grease, so we recommend asking a specialist store for help.
2. Charging cable or adapter
If you are using a cheap charging cable or adapter, your laptop may become unstable while charging.
In this case, using a different charging cable or adapter may solve the problem.
It is best to avoid cables and adapters that become abnormally hot, especially while charging.
3. Power Plan Settings
For those who play games,電源オプションAlthough your device may have the power plan set to "High Performance" or "Ultimate Performance," we recommend switching to "Balanced" while charging.
*Of course, if you have no symptoms, you can leave it as it is.
Which is better? Ultimate Performance vs. High Performance Power Plan
If the operation is unstable even after switching the power plan to "Balanced",電源オプションand click "Change plan settings" to the right of your current power plan.
Click "Change advanced power settings."
Open "Processor Power Management" and change "Maximum processor state" from "100%" to "90%" as shown in the image below, then click OK.
Finally, click "Save Changes" to finish.
If steps 1 to 3 above do not resolve the issue, consult a PC specialist, or avoid using the device while it is charging.
Or if your laptop is old, consider buying a new one.
