Question about HP Pavilion DV6775US 15.4" Entertainment Laptop PC Notebook
It has something to do with the power supply of your unit or the motherboard itself, especially when you isolate the battery and plug only the power cable and i wont turn on. In this case, you can reseat the power supply by removing the cables and battery when the unit is off, remove the screws below it, remove the hard drive, remove the optical drive then remove the power supply and reseat it. Then perform the steps in descending order (insert optical, hard drive, screws, battery, cables). Turn it on and observe if there are lights lit on the keyboard. If you don't know how to do this or if symptom persists, consult HP tech support for repair of your laptop..
