It could be the power turns off, or just hangs. I'm not there to see what you see.

Try this. Most of these will offer a boot menu if I hold down the Esc key and power up (do not let go of the key.) See if power stays on when the menu comes up. DO NOT PRESS ENTER, but do try the arrow keys on the menu. That key might be an Fkey but you can find out or know since you own this laptop.

Depending on that I decide what to consider next.
