The processor may not be good enough for Premiere Pro. It depends what type of media you will be editing.
Replace the HDD with a SSD.
Add more RAM.
I agree with Peru Bob. That laptop has one of those i7-branded CPUs that have only two physical cores and only four threads whereas most other i7 CUs have four or more physical cores and eight or more threads. What's more, that i7-6500U CPU has a maximum Turbo clock that's significantly lower with both cores in use than the stock speed of an i3 desktop CPU of the same CPU generation.
