Hi Khenglish,
I was wondering if you could tell me the value of one of the resistors on your 980m card? In the photo of the bottom of the 980m, it the one above the 'D503' in the top right.
Basically someone gave me a dead 980m mxm card identical to the one in your photo. Comparing the underside of the card with the photo you posted I've notice some components are missing. From the solder it looks like they were broken off rather than never being populated. I found a schematic of the Clevo p65x on the web and worked out the value of most of the missing components. Unfortunately the schematic is not for an MXM card so some bits are different, explicitly the part to enable power on the card which includes that resistor.
It's impressive that you managed to change the ram successfully! Thanks for writing about it.
