Unfortunately I think HP warranty policies state that you can only change by yourself the components covered by dedicated doors on the chassis bottom, such as the hard disk drive and RAM(obviously your upgrade parts are not covered by hp warranty and not supported by hp support).
So regaldess of how complicated the damage is to fix(most of the led indicators are soldered on the motherboard) you need to call the HP support and they will fix it, they are usually fast and you will have your laptop back in a week or so...otherwise you will probably lose your warranty if you try to locate and replace the fuse,replace the LEDs, replace the connectors...
it might be a connector plugged backwards but you should not directly try to fix it.

when you say won't power up, does it mean there is no indication of light whatsoever on the unit? If yes, then it means its having a power problem. it might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.
This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.
To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter in order to test the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.
Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.
Let me have a feedback if you need more info or help concerning this issue.
