Could you help me on this issue Update (03/05/2018) Symptoms the following turn on the computer lights the power indicator image on the screen nothing shows up the connection of another monitor also does not give any result passes some time the laptop heats up the cooler cooler turns on.

GG Y your motherboard is a HP part number 500755-001 and listed as a 6050172227701.AO2 From your images, #4 is a VIA VT8237S which is your Southbridge IC. It is responsible for things like your keyboard, USB ports and connectivity in general. The 3rd image is a VIA CN896 which is your Northbridge and its responsibilities are video related like connection to your display etc. In your case that is most likely the IC that is giving you trouble. As of now, I have not managed to find a schematic but will continue to look for one. Update (03/06/2018) @grgry okay ended up finding it. This should $GALILEO/GALILEO-6050A2174901-MB-X02-1113/schematic/sheet1 help you trying to figure out the circuitry.
