    Hi friends, first sorry for my poor English.
    I have a costomers MSI CX61 0NE (MS-16GB1 motherboard) and someone is badly heated by hot air station and N13P-GLR-A1 chipset is become a short circuit. I am clean all flux on the board and reball the BD82HM76 because close the heated area and i suspected solder balls get harmed.I am put 100% new N13P-GLR-A1 (GT635M) GPU and notebook works but only visible in device manager is intel 4000 graphics, nvidia is missing.I am try bios (E16GBIMS50I latest bios but i am not post the link sorry) but not help and if i try "nvflash --list" command or "nvflash -c -b backup.bin" command i get "no nvidia display adapters found" error. There no external eeprom arround and i am suspect nvidia inner rom (if it exist) is already empty or corrupt.
    Can anyone have gt635m vbios and help my stuation. Thanks.

    If you restart multiple times does it ever show in Device Manager? I recently had a fight with an Alienware 14 that keeps disabling the GPU. Every restart would bring the GPU up in a different state (missing entirely, not working, or rarely - working perfectly fine). My guess is something else on the board is damaged and the system BIOS is disabling it. If you can get the GPU up at all then you should be able to flash it, but I'm not sure that will actually fix it.

    Dead component, find it and replace it. Don't bother faffing around trying to find software fixes. The first thing I'd do is go over the board (or schematic) to find what's fried.

    This is just my opinion by the way, from seeing this issue many times. Never have I seen a dual graphics laptop with a missing gpu problem caused by software. It has always been a dead component (usually gpu). You may have also placed in a faulty chipset or soldered it wrong. On the other hand it could be a dead component somewhere. See if you can find the board schematics and scan across it.

    Is this possible the gpu internal rom or eeprom off board flash? I can not find any example or tutorial about this.
