I halfway put my laptop back together and powered it on to test it out. The system booted up fine but I noticed that I forgot to plug in the touchpad. While attempting to reconnect the touchpad connector to the motherboard, the laptop immediately powered off. There is absolutely no sign of power, including the battery charging LED. It sounds like I fried the MOBO but I don’t see any visual signs of that. Could there be any other damage besides the MOBO?
never remove any components or add while you have battery or power cable connected, its better to press power button 10seconds after removing them even to remove any from circuitry. Try boot without touchpad , probably wont work, if it doent take pictures of motherboard high resolution model number etc
