Hello, don't know where to post this hopefully get some answers.  I have a HP 7t-400 laptop that won't power up. I checked the charger and the battery both are fine. I opened up the case and other than fine dust no issues visible. I have checked power to the board and it is got power. Cleaned and re seated all connections and hard drives and tried new ones + ram. I read that the internal battery is also the closest reset. Unplugged all power held down power button to try reset. Still no power. I am computer literate and electronics capable. Any help much appreciated.

Hello  yes this is a laptop. HP 700t-400. I have tried many things to no avail.  I checked for voltages across the board in the points marked on the motherboard.  I get 21 v with it plugged in and battery 12v +. Whatever happens when you push the power button that few secs to power on is not happening. Not ram,chip,hdd,had,. I am at a loss as to why it just stopped working after it worked fine the night before. Tried cmos reset and all by removing internal battery.

Let me know if it's something you want help with. Thnx
