heh, i posted with this problem here some time ago too...
i contacted the e-support on/since march the 12th , but they are still making a fool of me it seems!
just try and give these words to google:
sony vaio fs summen
and you will find many many cases with this display problem... A lot of notebooks were already collected, but e-support tells me the don't have a confirmation that it is necessary to collect my notebook............
I am a programmer too, and i really love this notebook. But this buzzing noise makes me mad. Also my fan is running all the time... I read around, and not all the VAIO FS fans are running all the time it seems. I asked e-support on this problem. The asked me to try start up in BIOS an look if the fan will start there too. I did it, and the fan started. I told them. They told me to make a BIOS update. I did. Fan still running all the time. They told me that this is within specifiaction . And now i am really getting why so much people are talking about bad sony support and stuff... it seems they just want to calm one down, but not to try to solve ones problems.....
So, good luck...
