Lagging as in going lower frame rate in games than you expect or just not responsive in general tasks? Depending on what it is, my friend did have this problem just on normal daily tasks and I had him open the Omen software that the device came with and switch the mode to performance mode. Turned out it was set to silent. (if you have the GTX 1650 gpu it will not have this option). If doing this doesn’t fix it, check the task manager to see how much RAM is being used up, if that’s the issue you should find what’s using it up.
Yup this is what I was gonna say. What I have to add though is those GPUs are for things like engineering (air flow simulation for example), 3d modeling, animation, etc. They are typically more expensive than their gaming oriented GPU counter part which in this case as mentioned is a 3060. For video editing, you can find a 3060 or maybe even a 4060 or 4070 for similar prices to work stations like that with better performance for your use case.
