Sometimes, your Windows laptop may work slower than normal when you plug it into a power adapter.
This can happen because of several different issues. One problem is that your laptop may use less power to save energy when charging.

Another problem is that your laptop may have too many things running in the background or malware covertly being run in the background as well. These things use up your laptop’s resources and make it take longer to respond. They also need more resources for other essential items.

The third problem is that your laptop may have old graphics drivers1 or graphics settings that save energy. These can make your laptop work slower.

Solution 3: Check CPU/Adapter Temperature to Reduce the Lagging

Check the CPU temperature and power adapter to see if nothing works with previous solutions. You can use the software CPUtemp or a hardware device to measure your laptop’s temperature. 

If it is too high, you may need to clean the dust from the vents, fans, and cooling channels or move your laptop to a cooler place. You can also use a cooling pad or fan to help lower the temperature.

Check the power adapter

If the CPU temperature is average, there may be an issue with the power adapter. Make sure the power adapter is not damaged or loose. You can test the power adapter with a multimeter to see if it works correctly and delivers enough voltage and current to your laptop. You can follow these steps to test your power adapter.

  • Disconnect the laptop charger from both ends.
  • Inspect for any physical damage signs, including scorch marks, cracks, or breaks in the insulation, or plug.
  • Connect the multimeter power leads to the adapter.
  • Turn on the multimeter and power strip.
  • Switch on the adapter if it has a switch.
  • Read the multimeter to determine the voltage put out by the adapter. It should match the written rating on the label of your device. If not, it is time to forget the adapter and get a new one.
inspect for physical damage

Solution 4: Prevent Overheating by Improving Ventilation

Check laptop fans

The high heat produced by your PC components could be one of the reasons for any laptop to slow down or lag when charging.

A small amount of the power is converted into heat while your laptop is plugged in for charging, which needs to be dissipated. It can quickly build up and increase laptop temperatures if it does not find a way out. As a result, your laptop becomes sluggish in performance.  Therefore, you should not ignore your laptop lagging due to high heat levels.

We recommend you check the laptop’s fans and check whether they are spinning perfectly or have dust on them. If there is dust, we recommend cleaning them properly using proper tools. It is suggested that you should seek help from a laptop or computer technician. Also, if the temperature is too high, help your laptop vent the heat comfortably to resolve the problem.
