- Information
Some problems are relatively easy to identify and solve; however, others may require help from your network administrator or company technical staff. If you need to contact Toshiba, you will find information regarding Toshiba’s services at the end of this document. Before you contact Toshiba, please read the troubleshooting advice in this manual, in your computer’s user’s guide and/or in any manuals that came with your optional peripheral devices. Due to USB bandwidth limitations, you may notice performance issues if you are performing several resource-intensive tasks simultaneously (such as playing audio while simultaneously recording audio, transferring large files and using a high-definition web camera). This type of activity is common when running instant messaging applications. In such situations, the screen may go black or become unresponsive or there may be no sound from the connected audio device. Limit the amount of applications you have open at one time to avoid these performance limitations.
The contents below provide possible solutions to common issues and are in reference to Windows 7. Windows XP and Windows Vista procedures may vary.
A link to the drivers for all operating systems including Windows 8 are available at the end of this document. CLICK HERE.
