Do they send any warranty extension certificate n all?[DOUBLEPOST=1427656229][/DOUBLEPOST]Planning to increase ram.
Which ram should be compatible with existing ram?
Model 80E300GYIN
I've got the same laptop as you - 80E3GYIN
I didn't get any certificate when I extended my warranty.
I bought an 8GB 1.35v 1600mhz RAM stick and it worked perfectly alongside the existing 4GB stick. I've since given the 4GB stick away, and am using only the 8GB one.
This is what I bought - http://www.amazon.in/gp/product/B00CQ35HBQ?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00
