Please my hp probook 6460b core i5 don't have a battery,I connect it directly to a power source,just yesterday,I plugged in but all I saw was that,the led keeps blinking continuously and when I press the power button,it doesn't turn on

try another charger with the same voltage. It should provide at least the same current/power or higher

eventually it´s the battery

Mine was solved by turning of the laptop and switching the ram chips
Turn on after that
