Used Wrong Power Supply

ProBook 450 G 5
Microsoft Windows 10 (64-bit)

Good morning, All. My ProBook will not power on and the power/charge light does not illuminate. This is likely related to me using the wrong power supply. I have a work HP w the same voltage/wattage and probably got them mixed up. I’ve read an article that these laptops will enter a kind of protect mode if it detects the wrong power supply. Does anyone have the steps to recover from this mode if the laptop won’t even power on? Thanks for any help you provide!

Have you tried a power reset?
