I plug the power cord in the laptop and white LEDs blink once for 1 sec or 2(white colour) at the power button and at the CAPS LOCK button...when I press the power button to open the laptop nothing happens except blinking....next to the power cord an orange LED light blinks....it blinks 9 times with no pattern or something...just blinks orange 9 times and then does nothing....the battery is non removable !! It had windows 10 64 bit- LAPTOP: HP ProBook 450 G4....please help me!! (Note: pressing windows logo and B + power button did nothing...it seems that there is power at the laptop but literally does nothing)

1 Check for reset hole, if there is, reset it.
2 Check with another charger.
3 Since the battery is inbuilt, the next step will be to open the casing and disconnect, then reconnect the battery.

Try these and post the outcomes.
