I got a hp omen that came in for a no power repair. I specialize in mobile phones repairs but also do laptop to assist local shops that needs microsoldering jobs. This hp omen is missing the 3v on bios and also the main rail 3.3v is missing. Should I replace the power management chip? Where is the bios 3v generated

On newer gaming motherboards, usually only 5V should be present on the coil and 3V will be generated after pressing power switch.
Whats the mb part number?Any schematic available? -
Thats not the part number.Comment

Review any white text or white large silk screened part numbers on the pcb. Post their pics. Like ‘LA-****’, etc.Comment

Hi, my laptop wont boot at all
