I can't remember.. I can't find the documents I got with the laptop either. I bought this last december and I did ask the acer support guy whether the warranty will cover replacing motherboard. he said no.
And I got a pricing. http://www.notebooksolutions.ca/zc/acer-original-motheroard-ac54305-52902.html
That is the one they say will be compatible with my laptop.The other one is cheaper, so what will I be sacrificing if I get the other one?
I have another question. Since I am making a pretty big payment here, almost half the price of the laptop, I was wondering if I could get better specs? I noticed that there was a newer model of this laptop on amazon. that's why.
The first one uses the integrated video built into the CPU. The second one uses a dedicated Nvidia GPU. The second one is stronger for gaming and all things video (like rendering).
