Laptop Wont Power on. Power button flashes when Plugged in, stops when unplugged.

Good evening
HP Zbook G3 15
Please, I have a problem with my laptop
I installed Windows 10 on it and it was still working
And the battery was 40% and I went out for a ride and came back after two hours and found the side completely disconnected
As if dead, I reached the charger, but the device does not work at all. The charger bulb is working and there is a faint blinking on the power button. The charger capacity is 150 watts.
