Powered Laptop Automatically Starting Up (Unintended)

I recently had a hardware failure and replaced my hard drive with a new one. Then having done a fresh install of Windows 8.1 (which then was upgraded to Windows 10).

I'm having the same issue described here: Windows 7 machine starts up automatically when coected to power source

The difference being this happening in Windows 10, and actually on my personal laptop. My BIOS does not show a tab for "Power" or options similar to it.

I'd appreciate help on diagnosing the problem, and then help on solving the issue.
