A couple of weeks ago, I bought an Asus N46VZ from a local retailer. I was quite satisfied with my purchase, until I found huge scratches on the case. So I claimed a brand new unit, and they said that they would install new screen and touchpad protectors for the new laptop, since I already installed them on the defected unit. When I received the new unit, I brought it home and found a tiny scratch beside the touchpad, it must be caused during the installation of the touchpad protector, but I didn't care since it's so tiny. After a 2 weeks of usage, I found major scratches on the lower right corner of the display bezel. I don't know where it came from, I never even touched that area. It took me a long time to notice because the scratches must be viewed at a certain angle for them to be seen. The laptop's subwoofer that came with every unit of Asus's N Series laptops, also has the same finish as the display bezel, rubber matte, but it didn't have scratches on it, despite how many times I bumped it on my table or wall. I suspect that they scratches were also caused during the installation of the screen and touchpad protectors. I really don't like scratches on my gadgets, they annoy me a lot. Now I'm wondering how I can claim another unit, the units that I have received from that retailer so far are all defected. How do I convince them that these scratches were already there since I received the laptop? Thanks.
