I have a Hp 15-dy2762wm laptop and the laptop will not start up. When the power adapter is plugged in the power jack/ battery Led is flashing white every 8 seconds. The battery will still charge, when the battery wasn't fully charged the power jack/ battery Led would flash alternating amber and white. I removed the battery and plugged the power adapter in the power jack/battery Led flashes white. I disconnected the ribbon cable for the usb board that's next to the power jack and then plugged the power adapter in the jack the Led light does not flash stays solid white. When I connected the battery the light was amber until the battery was fully charged and the Led light turned white. I did try using a different power adapter that is good and having the same results. The laptop will not start trying any of the things I tried stated above. Wondering why the Led stops flashing when the usb board ribbon cable is disconnected.
