Return to the shop you bought from since you just bought it yesterday for 1-to-1 exchange. Try checking the laptop if it work and look fine at the shop before you leave.

Yes, always check a new laptop on the spot for any defects since you can avoid the hassle of travelling to the shop again to exchange for a new unit. 

well, can't totally blame Asus... shit could ve happened during transportation and stuff...

that's y u need to check thoroughly when u bought it, but before leaving the shop...

- incorrect about the 1 - to - 1 exchange info 
the correct way should be like this

1) you buy a laptop, any happen that needed 1 to 1 exchange, ( for obvious defect ), some seller will give you a new unit if they have another unit, if they do not have/ sold out the unit , how they give you ?

2)
-some seller, will took back the default item and claim back from Asus , because the unit are obvious defect, they have confident to get new unit from Asus.

- some seller will needed customer to get approval code from Asus before they give you another one to exchange,.this is because some defect may not so obvious, they afraid Asus not gonna give another new unit =)

the reason / example = you buy a Milo from Giant hypermart, when u back home, you found out its got problem , but the item still not over expired date, do u blame Giant ? no, cause the item is sealed , and not manufacture by  Giant , they as a middle only , they also buy the Milo from Nexxxx, and sell to you, if Nexxxx did not compensated them, they will die...  =)the example are for few dollar item, imagine the laptop mostly over 2k..== how the shop survive?
so in this situation , Giant will help you either get replacement from Nexxxx or will ask you direct go back to Nexxxx, its depends how you deal with them lol ... , if they willing help you, that would be nice  - cause this is what we call "after sales services"
-3) some buyer , they all look for very cheap price, and to be frankly , most of the seller will told them:" i can sell it cheap, if any happen on warranty, you no come back me, cause i earn u very tiny, i will not waste my time entertain u =) ... == " and most of the buyer will be so happy when they got very cheap price offer and forget about this situation, once the laptop have trouble that need to send warranty, they will suffer

At last, the shop replace a new 1 for me... Thumb up to the sales person who able to pursuit his superior to replace 1 before the ASUS make any decision...
