Hp Pavilion Dm3-1070es schematic needed

[scobie]

Hi unit was dead initially had 3.3v an 19v in so flashed new chip and replaced faulty bios chip (as it would not read in my programmer). Now get unit powered on but only 1/2 A current drawn and no video. I have 3.3v/5v/1.5/1.05. I have the Tahiti and the Arwen_a1 schematics but both are not correct for this model. U13 looks scorched. The motherboard markings are HPMH-40GAB4200-D430 AND ALSO ON MOBO PCB:41-AB4300-D00G. PWA:40GAB4300-D.

 

Any help is appreciated.

the specifications of which u13?

u13 is some kind of regulator but I cannot see the markings on it. If I had the schematic I can do more testing.

I reflashed bios with the second file in the bios package and now current usage goes to almost 1A but the screen stays white with no external output either. Maybe the screen cable is faulty also. I still need the proper schematic aswell.
