HP DV7 1070ed - shutting down problem - Page 2

The battery I first ordered, it seemed to be fake, while on the website it stated 100% original and the company have always good reviews.

I've ordered it again from the official HP dealer, but the led light is still flashing now and then. I mean, yesterday for example I was able to charge for few hours, then I was working without the adapter then again charging was fine.

Then the led light was steady, but it didn't charge and the adapter was "cold" like it was dead, but then the led light was on and steady. I've turned off the laptop, took out the battery and pressed 2 or 3 times the power button for around 30 seconds. After that the led light was on and steady right away and it was charging for few hours.

Then in the late night it started to flash again. I've tried to turn it off again and press the power button, but it didn't help this time. No it's like on and off. It's charging for few seconds and then it's off for a second then again charging for few seconds and off. Sometimes it is charging for about a minute or two, then off again.

Is the something with the power adapter or maybe it's something with the connector itself? or something else? 

The led light is flashing one time slow, another time fast and when I turn it off and take the battery out and put the power adapter back on, I usually can hear this "ticking" sound. I don't have another adapter, so I can't test it right away, but if it's something with the adapter I'll order it as well.

What do you guys think?
