probook 450 g5 not powering on universal charger

HP Recommended
Probook 450 G5
Microsoft Windows 10 (64-bit)


I lost the original AC charger for my probook 450 g5 so I bought a universal charger and it will not power on. no sound or lights except for:

a blinking white light when power button pressed and the charger is connected

and a blinking amber light when power button is pressed and the charger is NOT connected.


any ideas??

Smart chargers now can communicate with machines and machines KNOW which one it can / can't use. Please only use HP genuine charger or at least a third party charger which is compatible with your laptop.

This is the DC jack of a SMART AC adaptor.




The center pin is used to communicate with the laptop.


Almost all laptop manufactures are using them now.


And most are not interchangeable, so to have a Universal AC work for all is a long shot.


With AC Adapters and Batteries always purchase OEM.
