I own an HP Envy TouchSmart 15 Notebook PC product number: E0K05UA#ABA and Model: 15-j053cl
I had a couple plastic screw inserts that hold the right side hinge to the top cover of the laptop break due to very high strength of the hinges which caused the top cover of the laptop to pry apart from the base enclosure when opened (a problem many owners of this laptop model have had). Since I was out of warranty I ordered a replacement on Ebay using the correct part number 720570-001 and disassembled my laptop to make the repairs and loosen the hinges while I was at it. I swapped out all parts being careful to note where and how plugs and ribbons were connected so I could put it back together correctly. Now after having it reassembled it will not turn on.
I get a white LED light to turn on when I plug in the power cord AC adapter (should be amber/orange in color to signify it is charging the battery) but no other sounds lights or signs of life. I have attempted to remove the battery and power cord, pressed the power button for 8-30 seconds to drain power and do a reset and then try to power up with plugging in the power cord but it won’t turn on. I also tried to power up by removing one part at a time including the hard drive, two RAM sticks, and wireless card but still not able to turn on. Do you have any ideas for what may be wrong or steps I can take to troubleshoot? Is this possible a mother board issue? Everything was working fine before embarking on this repair.
