GT70 vibrations

Hello! I've just bought new GT 70 0NE, first week everything was fine, but now, when I rest my hands on notebook, I feel vibrations. Even worse, when I put notebook on my table, it starts to produce low noise, like subwoofer. Sometimes vibrations stop, sometimes start again, and it's little annoying. What is it? Is it normal? Should I return notebook to the store (I have 2 week moneyback) or medium to low vibratrions after first week of service are normal?

 

Could be that the chassis is a little loose; or perhaps a fan is causing the noise. As long as your temps aren't out of control, then there's no need to panic, although you should throw caution to the wind and use hardware monitoring programs to check your temps to verify that a fan isn't failing on you. Do you hear the noise when you apply pressure or put the laptop on a different surface? Is it fairly consistent?

Some noise from the fan is normal when it revs, but you shouldn't necessarily have "vibrations".
