The Sims 4 lagging and freezing on PC no matter what I do
wmoon123 That's more than I asked for and illustrates the problem: your CPU is overheating when the laptop is charging. It's running hot, but not too much, when you're playing on battery. For reference, anything above the low 90s will cause throttling. The Core Max is the maximum temperature on any CPU core at that time, so it's a useful if incomplete measurement.
The main reason the CPU is overheating is probably that it's trying to work harder than it would on battery, which paradoxically means it can't work as hard, once it overheats. But the heat from the battery itself, as it charges, may also be a contributing factor.
Regardless, this is a real problem that needs to be addressed. It's possible the laptop is defective in some way, but more likely that the fans or vents are blocked. If you're comfortable opening up the laptop, you can see for yourself. I believe this is your layout:

If the fans are working fine and the vents aren't blocked, and you're not playing with the laptop sitting on a blanket that would obstruct airflow or anything like that, then there may be a defect with the laptop itself, for example the CPU thermal paste could have dried out or been improperly applied. This is when you'd want professional help, hopefully within your warranty if you have one.
