I have a IdeaPad 3 laptop. I was playing a video game on my lap top while plugged into the wall. Everything worked just fine before that day. The graphics ran at 60fps and looked smooth all of a sudden they started dropping to only 17 fps and kept going down from there now no matter what I do like change lots of battery power plan settings or turn them off it runs very poorly when it's plugged in P.S. When I take the charger out it runs very good

What are the exact specs and which game? It feels weird because it runs great on a battery but stops when plugged in. I thought we should tell you the power plan is messed up, but you've already done that check yourself.

That video game, MGSV Phantom Pain, was actually performing really well for me over the last few months. My computer setup is set up with an 8 gigabyte of RAM, a CPU that's an i5-1135G7, and a 500 gigabyte SSD storage.

To clarify: running this game on the battery gives a good frame rate, but plugging in the laptop makes performance bad. Have you checked if the same graphics card is being used in both cases, meaning it's using the Nvidia GPU regardless of whether it's on battery or plugged in?

It uses two of those things: the Mx350 with a high score of 94 to 95 percent and an iris set at 4 to 5 percent. That means it also takes in 59 percent of my memories.

I see lots of people complaining that gaming laptops act slow when they aren't playing games all the time. Usually, this happens because you need to plug them in. A main reason is overheating. Laptop coolers are always small and light, so they can't keep up with a lot of heat. The fans also lack power. If you use a tool like HWMonitor or HWinfo, you can see how hot your CPU gets right now. For Intel chips, if the temperature hits 100 degrees Celsius, that means the processor is slowing down to stay cool until things get better. When it slows down, the CPU uses less power and goes slower because it's protecting itself from burning out. With lower performance settings, the CPU can still be working at full speed of 100%. What should you do? First, make sure your air vents are clear so the cooler can breathe well and check that the fan is actually spinning. Then, try changing your power plan to a "balanced" one instead of just "performance." Set the minimum CPU performance to around 20% in Windows. Even though this sounds strange at first, you might find it helps if you set up an advanced feature on the balanced profile where the max power is lowered from the usual 100% down to 90%. You might not notice a big difference immediately.
