HP Pavilion DV7-6110 (Core i7 Radeon HD6770) blank screen SOLVED - BIOS

[sopik78]

Guys,
let me share a problem I had with HP Pavilion DV7-6110, Intel , with 4-core i7, Intel HD graphics and discrete AMD Radeon HD 6770.
After pressing power button blank screen, fan spinning, no caps lock codes.
Schematic attached.

Reflashed BIOS and KBC (see attached files). Than I get image on screen and booted to windows, but I found both USB 3.0 ports not working, no power on connectors, so changed U13 /G547I) and now everything works well.

Good for you sopik78. I wish I could open your files, but this public computer I am using has no zip opener and the security on it will not let me download and install WinZip.
