Hello Folks, you could help me with A board view or schematics for my Dell 5411 LA-J271P. Its not doing the POST, only negotiating 20V at the USB-C for 5 seconds, then falling back to 5 V. no short int the power rails. The CPU Vcore Rail has 1.8 Ohms, wondering if this is too low. Any hints how to proceed diagnosting? -
Hello,
i am an informer Service Technician. And i was working 10 years diagnosting and repairing mostly Toshiba FSC and Lenovo Laptops. I still have fun to revive dead Laptops, now that i found out about the posibilitys in Mainboard in depth diagnostic, like voltage injection etc. I hope i can learn a lot from the community, thanks.
