Hi,
I own a ASUS Vivobook S15U Laptop with a Intel Core i5-8250U and a Nvidia MX 150 GPU. I mostly use the laptop at home for watching videos, few games, browsing the web etc. I have set the battery max limit to 60% and keep it mostly pugged in but sometimes when I unplug it and use it the whole system lags a lot and hiccups . I checked the Task Manager and noticed a strange behavior, the CPU frequency stays at 3.4Ghz for a few seconds and then drops down to 0.40Ghz for a few seconds and this then continues until I plug it again for a brief moment. I checked the CPU temps and it was around 70-85 C .Sorry I couldn't take screenshot of the Task Manager as I was not able to recreate the problem before writing this. I would like to know why does it do so and if anyone else faced this.
Thanks for your Time!
