M5100 graphic (red) on Precision M4700 instead of M4000 no display

Hello,

I read a post on this case of red Firepro M5100 graphic board not running on the Precision M4700 on this forum.
Interesting, very interesting.

So the pb I have now is when I put the original Firepro M4000 I got the same troubleshooting : I heard the fans for 3 seconds and the laptop shutting down. Exactly as if I had the incompatible red Firepro M5100.

I don't know what to do and need help.

Thanks, regards,

Fabrice

 

Hello, did you try a clear CMOS by removing the CMOS battery?
I found this link
Of course unplug the power adaptor and remove the battery before doing it!

 

Hi,

I'm still in a deep... My Precision M4700 won't start after a clear CMOS. I still have the same pb. Graphics seems to be not recognized and I don't know what to do.
If anyone have an idea, it would be great appreciated.

Thanks,

Fabrice
