Dear Lowyat Sifu or any Asus TUF Owner's

I just bought an Asus TUF F15 laptop.

I have a question:

When I on my power adaptor my screen goes blank screen (Black Screen) for a few seconds and when I off my power adaptor it will also goes blank screen for a few second as well.

Is this normal for Asus Gaming Laptop. As I never encounter this issue with my Asus Vivobook when I on or off my power adaptor.

Thank in advance for your reply.
