Latitude D620

The D620 (and simultaneously introduced D820) was Dell's first business-oriented notebook with a dual core processor available. Initially available with the interim "Yonah" Core Duo processors, it was sold with the first-generation mobile "Merom" Core 2 chips once those became available from Intel in the Fall of 2006; both run on a 667MT/s bus. It was initial sold only with Intel integrated graphics, but an option to upgrade to a discrete NVidia GPU became available after a few months. It replaced the raised pointing stick with a "low profile" model, and introduced the option of 4-cell and 9-cell batteries in addition to the standard 6-cell model. It uses DDR2 memory and is compatible with both PC2-4200 (533 MHz) and PC2-5300 (667 MHz) memory.
