The Latitude C840 is a Pentium 4M-based 15-inch business laptop that was released in March 2002. The C840's CMOS Battery is a 6-cell VARTA NiMH pack, located under the palmrest on the right side. This type of battery leaks nearly 100% of the time, and will easily cause damage to surrounding components if left unchecked. If you own a C840, remove this battery ASAP, and think carefully before buying one that doesn't work off eBay. This battery is a likely culprit. As of writing (in 2024), the C840 isn't quite old enough to have had most of them die from this battery, but if you're reading this 5 or more years from now, it's likely that a majority of unserviced units will be dead. The first parts to break will likely be the trackpad, as the battery in the C840 connects to the trackpad ribbon cable. If you see a C840 with a bad trackpad, keep this in mind!

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, CSx, 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 4-M). The GPU can also be upgraded on the C840/M50/i8200, from a GeForce2 Go to the Quadro4 Go 700 from the Precision M50. The Latitude ATG was a semi-rugged version of the D620, and was Dell's only semi-rugged offering, while their fully rugged offering originally consisted of the Augmentix XTG630, a D630 in a fully rugged case, and later the D630 XFR. C840 cloned as the Inspiron 8200 and Precision M50 Dell in 1993 discontinued its unsuccessful existing laptop computers. After hiring John Medica, who had led development of the very successful Apple PowerBooks, the company introduced the first Latitude portables in 1994. The 15" "Premium" line was the 8 series, until the E-series merged this line with the 6 series (Model numbers being along the lines of C8x0 or D8x0). The entry-level line was the 5 series, but as of 2015 the 5 series and 7 series Latitude laptops are the primary lines of Latitude laptops.
