Better motherboard for NV59C66U

I own a Gateway NV59C66U and the motherboard just died on it (the computer will not even post - it powers up for about 5 seconds, restarts, repeats). The motherboard is an LA5892P motherboard. Rather than just buy a replacement, I would like to see if I can upgrade the system to the newer Core Processors (Sandy or Ivy bridge). Does anyone know if there is newer motherboard with the same form factor that I can drop in? I tried looking at the current lineup of Gateway systems, but it looks like the motherboards are all a different size. I didn't look at Acer or E-machines. Thanks!

 

It's not like on the desktop- each motherboard is designed specifically for a particular notebook.
Sometimes the same mobo is used in two notebooks but one notebook with two motherboards is a very rare occurrence (not counting those notebooks that have two mobos- one with integrated graphics and one with dedicated one which is a normal thing).

So basically- go for a replacement.

 

Yes, I saw that the Acer 5551 and the Gateway NV53 all use a similar format board - but none of them give me a performance boost over the Core I7 620 (max for the NV59 board). I find it an odd business model that the laptop manufacturer's use. To me, it would make sense to maintain as similar parts as possible between manufacturing lines to reduce manufacturing costs. A common footprint PCB only makes sense...maybe they are trying to make sure that people like me don't just upgrade our laptops instead of buying new.
