Hi friend, I would like to ask you, if you have any schematic for graphic card marked DA0FM1VB8D7 rev: D for laptop Dell 6400 E1505, please? This card have not Vcore for GPU, if you turn up notebook cool. When the temperature rises, so voltage for GPU appears with value 1.18 V and laptop works. I can not find this problem. I tried to replace the chip Vcore GPU (ISL88) and GPU chip GO-7300, but the problem still persists. Thank you for your help. I really appreciate it. |

Hi friend, thank you for your reply. Where i find EMC4000? If it was the bios, so it does not work just cold? When I warm the place where is ISL88 (GPU voltage controller) and the laptop is working and on the GPU appear voltage about 1.18V. |
