bluetoothmacossettings
Before I upgraded to OSX Lion, I could open up the Bluetooth Preferences, select a device, click on the settings icon, choose 'Rename Device' and rename the Bluetooth device.
Now that I've upgraded to OSX Lion, the option is there on the same location, but it is called 'Update Name', however, it doesn't do anything for me. Is that just a dead GUI component that will get functionality tied to it later on, or am I doing something wrong?
Your trackpad preference page is an earlier version than 10.8. I think 10.7 or before, so this is likely a software issue** The 10.8 page has changed a lot compared to your screenshot.
In the lower left it should say trackpad battery level and have battery icon with percentage. Having had some bluetooth problems in the past it should give you a battery level even if it is zero, unless the device is not completely paired, possible hardware issue.
With 10.8 under the Bluetooth preference page it will give you a list of all Bluetooth devices that have been paired with your machine, at the bottom below the devices should be a + - and a sprocket with a drop down menu that includes connect, rename, add to favorites, update name, update services, and show more info. The - will delete the selected device, I would suggest you delete the ghost mouse and maybe even the trackpad and try to pair the trackpad again. Also on the bluetooth page I have discoverable not selected.
If you are running 10.8 and you have Apple Care I would contact Apple as your screen shot is showing an earlier version than 10.8 as far as I can tell.
It seems this has to do with your older macbook pro because I have a more recent iMac and my Bootcamp version shows Bluetooth devices. When did you download that version of Bootcamp? If you're still using the original version from years ago, you may want to try downloading a new version as it may include the Bluetooth capability. If not, your computer may just be too old. Hope this helps, good luck!
