Dell latitude c640
Hi
Both Dell Part numbers 18THT and 5W299 are 8X DVD-ROM Drive Modules. DPN 18THT is compatible with Latitude C series and DPN 5W299 is compatible with Latitude D series. The two drives have different and incompatible connectors.
Your Latitude C640 is a C Series Latitude. You can therefore not use DPN 5W299.
If you need a DVD drive module, get DPN 18THT or an alternative Latitude C series drive.
