Bluetooth is not at all working on my dell inspiron 15R N5110 after i installed win 8. I downloaded several Bluetooth drivers from dell, but nothing seems to work. i Have a Bluetooth icon on my task bar, but when i click there for options, it is blank.

I see there is Latitude 10 or Latitude ST2E tablets. What is the difference? I see there is a BIOS update version A04 for the Latitude 10. There is a BIOS update version A03 for the Latitude ST2E.

Thanks for quick reply. And what should I notice / care about if I decide to buy online. I heard that I must use same mHz speed for both RAMS. Wouldnt more than 4GB work in 32bit UBUNTU 12.04 ?
