So I´ve had my T902 for a few weeks now and I've been putting up with a really annoying high pitched whine or hissing noise (driving me absolutely crazy when I'm in a quiet office). I can´t really pinpoint it but the sound is easier to hear around where the ram is situated (probably because of the air vents). I can still hear the whine when the laptop is 'sleeping' although not quite as loud. In addition when in sleep mode I can hear a very faint rythmic beeping too but I'm not sure if this has anything to do with the main problem. Anyone else experience anything like this? btw I´ve tried swapping the ssd, unplugging the fan, removing the battery... still whining. I had a technician come by last week and he decided that it was probably the motherboard so he ordered a new one. Today he came by and swapped it (and in the process ripped one of the speaker cables and put some nice scratches into the lid... great) but it hasn't helped at all. The technician proclaimed that he couldn't hear the noise anymore, but I think he just didn't want to deal with it anymore or get of from work :/ Any other advice? Is this acceptable or should I try to make the take it back or give me a new one? FYI I have no history of super-hearing or anything like that and other people have confirmed the noise, although somewhat older people (naturally) doesn't seem to pick up on the noise quite as much.
