I did a search on this Forum and could not find anyone who has reported a similar issue so I decided to post this.
I have a Jambox Bluetooth speaker and I was able to pair it successfully for a few days after setting up my new Lenovo X220T Tablet on 6/6/2011. However, today (6/12/2011), when I tried unsuccessfully to play music through my Jambox speaker, I discovered that the Bluetooth choice had totally disappeared as an option when I brought up the Software Wireless Radio software with [Fn] [F5]. Also, the existence of any Bluetooth capacity had also disappeared from Device Manager. Additionally, when I then attempted to install the Bluetooth driver for the X220 Tablet from the Lenovo website, the driver would not install and indicated that it was not able to install because it could not find Bluetooth on my computer.
I spoke with a customer service representative (CSR) at Lenovo service in Atlanta, GA on 6/12/2011 at 4:30 PM PDT. We restored the original BIOS settings and the Bluetooth, which had disappeared earlier, now showed up in wireless devices.
The Lenovo CSR ssigned me a case number. However, oddly enough, he could not find a record of my machine in the system even though it had arrived on 6/2/2011 and I attempted to register the machine twice online over the past week..
The CSR recommended that I call Lenovo at +1 (888) 776-0920 8:00 AM EDT to provide the case number and ask them to register my computer in the system manually, even though I made the two attempts to register it online and Lenovo had emailed me two Excel spreadsheets prior to the arrival of my X220 Tablet, both of which contained a worksheet entry, "Registration Successful"
Bluetooth started working again after the BIOS reset but the frustrating thing is I still don't know why it suddenly disappeared from the X220T and I am concerned that this strange behavior might recur. Additionally, after listening to music on my Jambox for 30 minutes or so after regaining the Bluetooth connection, I lifted the laptop onto my lap and the Bluetooth connection suddenly disappeared after this little bit of movement and I have not yet been able to restore it, although Device Manager does show entries for two Bluetooth radios, Microsoft Bluetooth enumerator and ThinkPad Bluetooth 3.0.
I wonder if the WiFi radio might be interfering with Bluetooth? I think that I'll next try connecting the X220T to my cable modem directly via a wired Internet connection and turn of WiFi to see if I can get a more durable Bluetooth connection.
This is my first ever Lenovo purchase, so I have not known what to expect with this new machine. Otherwise, I have been pleased in my first week as an owner of the X220T tablet. Anyone else out there reporting similar issues?
