You can use the Toshiba Satellite 5205 guide for removing and replacing the DVD/CD-ROM drive or the keyboard. On this model you have to remove the keyboard in order to remove and replace the DVD/CD-ROM drive because the optical drive securing screw is located under the keyboard. Always start laptop disassembly with removing the battery or you can damage the system board if you accidentally touch it with a screwdriver and shorten traces. Removing the keyboard strip is not very difficult, use your fingers to release the plastic latches. If you want to replace the keyboard, do not forget to unlock the connector on the system boar before you pull the cable.
