 Interference

If you’re running Bluetooth and Wi-Fi® at the same time, interference can affect the Bluetooth

performance. This is most noticeable if:

–You try to transfer large amounts of data, such as with file transfers.

–Several Bluetooth devices are operating in an office simultaneously.

 Speech Recognition

Bluetooth audio has not been fully developed for speech recognition. Therefore, for speech

recognition, we recommend that you not use a Bluetooth wireless headset.

 Disconnection

Some Bluetooth devices disconnect when they go into power-saving mode. Most devices

automatically reconnect when they become active again.

 Incompatible drivers

If you attempt to install other wireless headset or other audio drivers, such as Bluetooth or USB,

over the Tablet PC audio drivers, a malfunction of the Tablet PC audio system might occur,

because the drivers might not be compatible.

 Interoperability

If you are having issues with interoperability of Bluetooth devices, contact the manufacturer of

your Bluetooth device and check its compatibility with the Bluetooth software installed on your

Tablet PC.

 Security

Bluetooth devices use a passkey to create a secure connection between the Tablet PC and the

Bluetooth device. Although the passkey exchange helps to secure your data, Bluetooth wireless

technology shouldn’t be considered completely secure.

Audio Issues

No sound is coming from the built-in or external speakers.

 Ensure that nothing is connected to the audio in/out port. Connecting headphones or external

speakers disables the built-in speaker.

 The volume might be set too low or muted. Swipe in from the right, tap the speaker icon, and

adjust the volume setting. You can also use the volume buttons on top of the Tablet PC to turn

the volume up or down.

 The integrated audio components might have been overwritten. If you install a third-party

audio device (such as a USB or Bluetooth device), the integrated audio might stop working. If

this happens, reinstall the audio drivers. After you install these, if you still have issues with

audio, contact your system administrator or service provider.

System Issues

The tablet seems to be operating slower than usual.

 Reboot the tablet.

 The hard drive might be full or nearly full. You can free up space on your drive. Type disk

cleanup in the search field and then select Free up disk space on this PC from the search

results.
