I could've sworn my Aspire One 533 came with Bluetooth but I installed Windows 10 on it a while back and just noticed now that Bluetooth doesn't show up. I thought I saw Bluetooth on it on the Windows 7 Starter that came with it but don't see it popping up now. Based on past experience, I know that Windows 10 can miss certain things when installing on legacy hardware. After searching a bit on the Internet, I see some articles saying it came with Bluetooth 3.0 while some others said it was an option. Can anyone confirm if all 533s sold in the US came with Bluetooth? If it was an option, does anyone know the partnumber of the BT module and if it would be a simple plug and play once you take off the bottom cover? Thanks in advance!
