Bluetooth problem

Note: Check your connection anytime and ensure that no other Bluetooth-enabled device is searching for
the device to which you want to connect. Simultaneous searching is not allowed in the Bluetooth connection.
• Problem: Sound does not come from the Bluetooth headset/headphones but comes from the local
speaker even though the Bluetooth headset/headphones is connected using a Headset profile or AV
profile.
Solution: Do the following:
1. Exit the program that uses the sound device (for example, Windows Media Player).
2. Go to Control Panel, and ensure that you view Control Panel by Category.
3. Click Hardware and Sound ➙ Sound ➙ Playback.
4. If you are using a Headset profile, select Bluetooth Hands-free Audio and click the Set Default
button. If you are using an AV profile, select Stereo Audio and click the Set Default button.
5. Click OK to close the Sound window.
• Problem: PIM items sent from the Windows 7 operating systems cannot be received correctly into the
address book of any other Bluetooth-enabled device.
Solution: The Windows 7 operating system sends PIM items in XML format, but most Bluetooth-enabled
devices handle PIM items in vCard format. If another Bluetooth-enabled device can receive a file
through Bluetooth, a PIM item sent from the Windows 7 operating system might be saved as a file
with the extension .contact.

ThinkPad pointing device problems

• Problem: The pointer drifts when the computer is turned on or after it resumes normal operation.

drifting might occur for several seconds under the following conditions:
– When the computer is turned on
