Recently got myself Sony C Series C2S/H 13.3" model.

However it has recently started to make a whining humming high pitched noise, the kind that you can only hear when you turn your ears towards the sound.

It seems to be come from the hard disk drive area and is audible only when its very quiet all around

Anyone know what this high pitch whining humming noise is and should I be concerned about it

Thanks
