@jr48 I am not convinced that it needs a replacement just yet. You do want to at least disassemble your laptop to take a look at what is going on. Download the service manual [http://www.hp.com/ctg/Manual/c02745864.pdf|from here] Page 98 of that manual will tell you how to remove the motherboard. After that remove the CPU and clean the complete board with 90%+ isopropyl alcohol and a soft brush.Check for any missing, burned or otherwise damaged component. If you give us any identifier on your motherboard, I am sure we might even find a schematic for that. Check your AC adapter and your power on button etc. as well. If you find an area that shows corrosion/debris residue post some images of your board with your question. Use this guide [guide|21499] for that so that we can see what you see. worst case is that you may need a replacement motherboard (part number 594028-001) which is available for around $70USD. cheaper than a new laptop and keeps yours out of the landfill.
