If the laptop shows any signs of life (e.g., lights blinking, fans spinning, but no display, or it gets stuck on the HP logo), you might be able to force it into the Windows Recovery Environment (WinRE) or the HP Recovery Manager.
You can't fully reset an HP laptop without turning it on, but you can use **HP Cloud Recovery** on another computer to create a bootable USB for reinstalling the OS. For hardware resets, remove the battery (if possible) and hold the power button for 15+ seconds.
