Re: dell xps 13 9300 fdq30 la-h811p rev:1.0 bios
The same problem. Logo and nothing else. I try to reprogramming BIOS chip few times with diferent dumps. Nothing. But. I found, that one of the C-USB didn't work, even power supply, so i found bricked chip TPS6987D, it was very hot, I replaced it, but the issue persist. Maybe PCH is bye bye. Any idea?

Re: Lenovo G560 LA-5752p NO Power No Light
Also SUSP# = 0.Programing EC didn't help. CMOS battery reset solve the issue.
