Dell Vostro 14 3401, heating issues

I have purchased Dell Vostro 14 3401, which has 8 GB RAM and 1 TB HDD, i3 processor 11 gen, windows 10 and MSO came along with it.

When I run for few minutes, I can feel the heat in the bottom of the laptop where battery is located. Added to it, the charger that can along with is a 45w charger, and it is becoming super hot. The windows is going with disk space 100% all the time and running any application is felt like system is stuck. I kept it running empty for 2 hours and the issue is still the same with 100% disk space, though I dont see any installations running.

What could be the issue with OS ? Is the heating issue of laptop due to disk space 100% all the time ? I have even replaced the piece and still the problem didnot go. I couldnot even understand why charger is super hot ?


Did anyone facing same issues ? Any ideas how to resolve it ?
