Sorry if this is a newbie question, but I couldn't find anything concrete around the web. I have a Sony Vaio VPCF121FX and it has a motherboard soldered GPU (GT310M). I want to know if it's possible to upgrade this GPU with a GT445M or any other that may be supported.
@: If it is possible, I'm aware that soldering things to the motherboard is something dangerous.
@: All I could find is that it's not supported because the GPU is soldered to the motherboard, but in case my GT310M stop working, I would have to solder another GT310M to replace. I know it's not something that easy, but I suppose it's not impossible to solder a GPU, or it is?
@: In case it's possible, how can I know what GPU I would be able to solder in my Sony's motherboard?
Thanks for attention and sorry for bad english (I'm brazilian and not very used with english).
Peace, Eduardo Barth.
