I do currently own a Asus x551ca-hcl1201l notebook and my question is that how do I make the Bluetooth work fine after updating to Windows 8.1? I basically had a problem in the device manager and I uninstalled it and see if it will detect the hardware again but it didn't. I thought maybe it would work fine but when I tried to use Bluetooth on my phone it will connect at all. I did try to remove it and re pair them and it worked but it won't get connected when I try to send a pic from my phone to the notebook. I basically ended up had to recover my system and put back Windows 8 and it works fine but maybe someone here would know how I can fix this problem since I would like to use Windows 8.1 since it's more updated. Here's a link to the drivers for my notebook but do you see what driver will fix it for Windows 8.1? Notebooks & Ultrabooks - X551CA
