Thank you for purchasing the Toshiba Service Manual CD. All the manuals are in .pdf format and can be viewed using Adobe Acrobat Reader. The latest version of this program is included on this CD. Once installed you can open the individual manuals and print off as required. As the Toshiba manuals are a bit lacking in Troubleshooting information I have included a troubleshooting manual from Compaq. If you have any problems please e-mail me at t_u_k_2004@hotmail.com I hope you are happy with your purchase and that you will leave positive feedback for me on ebay. Regards, Tim technitron_uk
