HP ProBook 4520s won’t turn on

Please help me.....

My laptop is not turning on. I use my laptop without battery as the battery is faulty. It works fine with A/C Adapter. It was working fine yesterday but today when I plugged it in, the charging light blinks 2 times. I tried hard reset but it doesn’t turn on. It doesn’t show any power light or hard disk light

When I plug the charger tightly into the laptop, the charging white blink 2 times. Then nothing happens. But when I plug the wire loosely in the laptop, the charging orange light blink 8 times every time I press the power button.
