HP omen 15 dc100 charge led blinking, not working

[Tareqash]

Hello! I have an HP Omen 15t dc100 gaming laptop. There is an LED next to the DC jack pin/charge port. Plugging in a charger, that LED become white , then nothing happens.

Pressing the power button causes that LED to blink, and it'll blink once every time i press the power button. All that being said, the laptop does not power on at all.
This happen when i replaced my old ac adapter which not working anymore. Then this problem came

Thank you for your replay

after I bought a new original hp charger 150w the laptop is working and charging but I got another problem where the laptop starts to shut down suddenly, I installed a software to monitor the CPU and GPU temp and I figure out that the laptop is getting too hot and shut down  only when the ac adapter is plugged in

please  tell me if you need any details or info
I appreciate your help

Unfortunately, that didn't help at all 
can u please provide me with the proper original charger information
because if I charged the laptop without using it and when it fully charged i unplug the charger and use it, the laptop is performing perfectly

so I guess the problem is with the charger or the the charging circuits
