Hello everybody,

my new Portege Z30-b-138 produce an annoying level of electric noise (also known as "coil whine").

It is not a cooling fan or hard disk noise (the HD is SSD) but is coming from the motherboard and the pitch change as the workload increase or decrease.

Except for this problem, everything else is working fine.

Anybody know if this particular problem is covered by the warranty?
Can I RMA it asking to fix it for free?

Thank you
Gianni
