Operating System: Microsoft Windows 11

1 1/2 year old notebook will not power up. No power indicator light. Power supply is good. Looking for a main board schematic. Main Board # sps n20292-601.
Any help would be appreciated.

HP does not have any motherboard schematics available for any of their PC's, probably because they replace motherboards rather than repair them if a motherboard is faulty.

 

All that is available is the service manual and it is only for the 17-cn1xxx model series.

Thanks Paul, 
I appreciate the information and suspected as much. I am old school engineer and troubleshoot to component level. I was able to determine the board is missing the 3.3V supply. A schematic would speed up the repair process. I downloaded the service manual which is fine but lacking on the detail I need.
