Asus x51rl wont always switch on?

Question

HiI have a new asusx51rl laptop.when i switch the power button on, you can hear the hard disk spin and dvd drive spin (no disk inside), but there is nothing on the lcd display.After about six attempts it will then load as expected with the display.this happens with both battery and ac power.is this a fault, or is there something that i can disable to get it to load up everytime?many thanks
