Asus K53E-BBr17 will not power up

[KAST7]

I changed the DC power jack on my laptop because the original was bad. After replacement I plugged the charger in and the orange power light came on so I powered up the computer and it worked fine. The battery charged up and after I used it for an hour I shut down the computer. Later the same day I plugged the computer in and then I pressed the power button and the computer wouldn't turn on. The orange light is illuminated when plugged into the DC Charger yet the computer will not power up.
Any idea what can cause this? What trouble shooting steps should I take.

remove the battery, press the power on button without battery for around 1 minute, put the battery back and try powering on
