well your leaving a lot to the imagination..is the hard drive light working..plug it into a external monitor then boot it..then we can go from there..

Did you take out the battery when you changed the hard drive. It still has power in the circuits when the battery is in. You might have fried it. I would try taking out the battery and push the power button a few times (to discharge any power in the board) then make sure the hard drive is inserted properly. Good luck.

I had the same problem with my HP laptop some years ago. you have a broken cable/cord and it is the part that is permanently attached with your power pack. If you look at the cord that plugs into your laptop, you can be able to see the faulty part of it. it is usually very flexible or swollen. You can either take it to an electrical technician to change that part of the cord. Your power pack is still ok, but have the technician to check it out first before you change the cord. Else, you may have to get another power pack. below is the full specification of the power pack that is recommended for your laptop.
