i take back to shop and told them it cant turn on..

i request new laptop or change other model since mine is display set and purchase within a week..
they say wait check izzit software problem.. say they will format/recovery if cant spoil..
i want see how technician do since it cant turned on ;D
edit: damn, the shop say i registered on asus website for 2year global warranty, means the pc is mine. i can't change other laptop already. they say after reg on asus website, 3 day later the asus will update and activate the warranty.
