ProBook 4540s not charging. Charging led blinks 9 times

Hp Probook 4540s
Microsoft Windows 10 (64-bit)

Hello! My ProBook 4540s was working fine until few half hour ago, when I unplugged it to move it and then attempted to plug it back in, and it stopped charging.  When plugging in the power cord the light above the power jack (and no other lights) flashes white 9 times.  


This is the exact same problem as posted here

but there is no solution.


Please help
