My HP 15 EF series laptop just went off while I was using it. It had gone off before and wouldn't come on when I press power button. But the battery indicator would be blinking when I plug it. It will first show white light after sometime it will show Orange light but still blinking.

I tried hard reset and it came on but has gone back to the way it was after 3 days.

What could be wrong with it and how do I solve it.
