Customer support guys RARELY know what they're talking about. When I was in Iraq with nothing to do (due to immenent base closure and a night shift) I went on to websites just to mess with them, asking questions I knew were easy to answer, but wouldn't be in their answer lookup fact sheet. (what is the cooling block for this product made out of?)(they always said plastic)
...anyway, laptops, with the exeption of expensive ones with desktop-type processors, always have the cpu and gpu soldered on the motherboard, and there is no way to 'safely' overclock them, or upgrade them.
