Latitude C series

The Latitude C-series notebooks covered the range of processors from the Pentium 166 MHz to the Pentium 4-M. Models in this series included the CP (Pentium processors), CPi (Pentium II processors), CPx, C600 and C800 (Mobile Pentium III processors), CPt, C500 and C510 (Celeron processors), C400, C610 and C810 (Pentium 3-M processors) and C640 and C840 (Mobile Pentium 4M).

C series laptops were notable for their consistent and interchangeable accessories across this wide range of processors. The series was one of the first to offer the UXGA 1600x1200 resolution display and included a NVidia GeForce MX400 32 MB video accelerator to complement the display requirements. A robust design made it a favorite in harsher climates; however, this design lacked the visual appeal of many of its competitors.

The most popular of the C-series included the C800, C810, C840, and later the C640.

The later C-series models mostly had near clones sold as the Inspiron 4000 and 8000 series:

    C840 cloned as the Inspiron 8200
    C810 cloned as the Inspiron 8100
    C800 cloned as the Inspiron 8000
    C640 cloned as the Inspiron 4150 and as the Inspiron 2650
    C610 cloned as the Inspiron 4100
    C600 cloned as the Inspiron 4000

An interesting note on the C840 is that it was the last Dell notebook (along with its sister models the Inspiron 8200 and Precision M50) to have both a "fixed" optical drive as well as a modular bay, making it a "three-spindle" notebook. The modular bay could also be used for a second battery identical to the primary battery rather than a special modular bay battery. It used a Pentium 4M processor and DDR SDRAM. The Dell C840 also supports 2 gigabytes of ram.
