Hi everybody,someone have boardwiev file for toshiba c660 LA-6842P?
On this laptop,someone tried to repair it and burnt out mary power ics,first i replaced 3 fets on alw power lines and ic for this lines,then gfx_power ic,cpu_core ic and now i have power everywhere but with processor inserted i cannot power it on,it turns on for maybe 1/10s,without processor i turn it on,on cpu_core i have the right voltage.i tried also another good processor with the same result.I believe that is problem somewhere in processor curent sensing circuit. Board have no resistors and caps marked ?Some ideas or boardwiev?
