How To: Fix Dell Truemobile 355 Bluetooth + EDR on Windows 7
One of the few problems that have really been giving a bad rap to Windows 7 users is the loss of proper Bluetooth Connectivity on Dell Laptops, specifically the Truemobile series. The cause is, unsurprisingly, a lack of Dell support – no updated drivers. In fact, if I recall, my Bluetooth wasn’t working properly on Windows Vista either, which the computer came pre-installed with. Since the problem is Dell Drivers, the solution is fairly simple: Screw Dell, set it back to the Windows Drivers.
Open up Device Manager.
Once there, right click “Dell Truemobile 355 Bluetooth + EDR” and click “Update Driver Software…”
You then want to “Browser [your] computer for driver software.”
Then click “Let me pick from a list of device drivers on my computer”
Select the bottommost “Generic Bluetooth Adapter” and then wait forever for it to install. (Yes, this one takes forever for some god awful reason, but it seems to consistently work).
The next step is disabling the “Power Management” feature to turn this device off. (Since Dell has crappy driver support, this only helps to cripple the usage of Bluetooth).
Right click your new “Generic Bluetooth Adapter” once the Device Manager refreshes.
Click the “Power Management” tab in the properties dialog, and make sure to uncheck “Allow the computer to turn off this device to save power.” Once you have done that, you should be good to go! No more Bluetooth Problems on your Dell =)
In this demonstration, I used a Dell Inspiron E1705, though this problem plagues many, many other Dell Laptops running Windows 7.
