Enabled Turbo Boost is hard to switch off

Most modern laptops have their Turbo Boost option activated. Because of this embedded system, the laptop’s cores are able to perform at their full potential. This is more common when the CPU is under stress. All of your heavy-duty games or programmers must run smoothly only if the laptop’s core is optimized.

However, when the laptop is charging, the Turbo Boost feature can cause issues with the laptop’s smooth operation. Even if it’s fully charged, there’s a chance it will begin to lag.

Thermal Throttling

However, thermal throttling is still a strong possibility and should not be overlooked! It is common for your CPU and GPU to overheat when under a lot of stress. As long as this heat is properly dissipated and not a problem, you may notice a decrease in performance. As a result, performance is reduced to a minimum to prevent damage to your components. Because you’re generating additional energy while your laptop is charging, this problem is only exacerbated.
