I've seen instructions online about how to add Bluetooth internally to Acer laptops, which almost all seem to have either a Bluetooth switch or button... except no Bluetooth module. However, I haven't been able to find info on the model I just bought (Acer Aspire 5520). It has a Bluetooth button, but it says there is no device when you press the button.

So what I am wondering is, is there a way to find schematic diagrams for my motherboard to find the location of the Bluetooth pins, if in fact I do have one?

Acer's site says your model has bluetooth
"he Acer Video Conference solution integrates one-click, real-time video and voice over the Internet to give you mobile and flexible communication capability. This solution includes:

• The Acer Crystal Eye webcam supporting enhanced Acer PrimaLite™ technology for superior low-light performance.
• The Acer Xpress VoIP phone3, which provides powerful audio capability with support for IM services and features beam forming, echo cancellation, and noise suppression technologies.
The Acer InviLink™ 802.11b/g1 Wi-Fi CERTIFIED® solution supporting Acer SignalUp™ wireless technology provides far-reaching, stable networking.
Gigabit Ethernet allows for faster, more efficient and more secure network connections while downloading or uploading large media files.
Bluetooth® efficiently connects to a variety of mobile devices with ultra-fast data transfer rates."

I highly doubt they would have it disabled. Go to the Device Manager and expand all of the +'s. Look for any yellow exclamation points or red X's. You may need to enable the device or reinstall the driver

According to this link, it does not have Bluetooth: Acer 5520

There is a button for it. There are no question marks or anything in Device Manager. Apparently none of the US versions of Acer notebooks have Bluetooth. Except the motherboards all have spots for a module. I've seen instructions on how to add it in other models, but can't find it for this.

As I understand it, it's cheaper to just build one motherboard and only add the components that you need (rather than to build in all the components and then disable them). So the traces for the bluetooth probably do exist - but it's gonna take someone familiar with this to figure out how to hook it up (if it is possible).
