The Impact of Using a Different Charger on Your Lenovo Legion 5’s Gaming Performance and How to Restore It


How to fix low FPS after using a different charger for Lenovo Legion 5?

I have a Lenovo Legion 5 (3070, R5) laptop that normally runs games at above 50 FPS. However, after I used a different charger at work that charged slowly, the FPS dropped to 15-22 even when I plugged in my original charger at home. The performance mode is enabled and there is no battery saving mode on. What could be the cause of this problem and how can I solve it?


Low FPS (frames per second) can ruin your gaming experience and affect your performance. If you have a Lenovo Legion 5 (3070, R5) laptop that normally runs games at above 50 FPS, but suddenly drops to 15-22 FPS after using a different charger, you might be wondering what is causing this problem and how to fix it.

The most likely cause of this problem is that your laptop’s battery has been damaged by the different charger. The Lenovo Legion 5 has a feature called Hybrid Mode, which allows the laptop to switch between the integrated and discrete graphics cards depending on the power source and the workload. When the laptop is plugged in, it uses the discrete graphics card (NVIDIA GeForce RTX 3070) for better performance. When the laptop is running on battery, it uses the integrated graphics card (AMD Radeon Graphics) for better battery life.

However, if your laptop’s battery is damaged, it might not be able to provide enough power to the discrete graphics card, even when the laptop is plugged in. This could result in low FPS and stuttering in games, as the laptop is forced to use the integrated graphics card or lower the performance of the discrete graphics card. This is why you might notice that the FPS drops after using a different charger that charged slowly, as it could have affected the battery’s health and capacity.

To fix this problem, you have two options:

  • Option 1: Replace the battery. This is the most effective and permanent solution, as it will restore the laptop’s power and performance. However, it might also be the most expensive and time-consuming option, as you will need to buy a new battery and install it yourself or take it to a service center. You will also need to make sure that you use the original charger that came with the laptop, or a compatible one, to avoid damaging the new battery.
  • Option 2: Disable Hybrid Mode. This is a temporary and quick solution, as it will force the laptop to use the discrete graphics card at all times, regardless of the power source and the battery condition. However, it will also reduce the battery life and increase the heat and noise of the laptop, as the discrete graphics card consumes more power and generates more heat than the integrated graphics card. To disable Hybrid Mode, you will need to follow these steps:
  • Open the Lenovo Vantage app on your laptop.
  • Click on Device and then on My Device Settings.
  • Under System Settings, click on Power.
  • Under Power, toggle off the Hybrid Mode option.
  • Restart your laptop for the changes to take effect.
  • After following either of these options, you should be able to enjoy your games at high FPS again. However, you should also monitor your laptop’s temperature and fan speed, as they might increase due to the higher performance. You can use a software like HWMonitor or MSI Afterburner to check these parameters . You can also use a cooling pad or a laptop stand to improve the airflow and ventilation of your laptop.
