The good: I initially bought this laptop for myself and then ended up passing it on to my son when I bought my new desktop. I purchased my Dell Latitude c640 laptop in 2003, when I began my studies at Colgate University. At that time, this laptop was a mid-range notebook. i bought this product last year, it has Intel Pentium 4 M 2Ghz processor, 20gb hard drive, 256mb RAM, and some installer cds.

Solid Pentium 4 class laptop from Dell The Dell C640 may be an older model yet it is surprisingly adroit with Windows XP SP3 running 512MB of RAM. Good Light...For the Most Part I work in security and need the ability to quickly scan dark or dimly lit areas for leaks, fires and intruders.

Having owned this laptop for over a year I am still extremely pleased with how it performs. I have used a C640 for 2 years and it is dramatically better than the C610. The graphics card was very good when first released.

Not as good as expected Very quick delivery. Description did not mention keyboard converted from AZERTY (or something) using stick on labels.

Dell Latitude C640

Pentium 4 impact in a thin and light notebook for Dells ultimate in "power density. With Intel's Mobile Pentium 4 Processor, the C640 boasts the highest performance ever in Latitude thin and light design. Combined with a new 32MB ATI MOBILITY RADEON 7500 graphics engine, this notebook is designed for road warriors who require maximum performance "to go".
Creating a really great business notebook means creating high value solutions in addition to top-notch specifications. So our new high performance C640 doesn't skimp on the hardware; compared to its predecessor, the C640 incorporates a faster chipset, faster memory, a new video chipset with significant improvements in 3D performance, faster hard drives, and higher density batteries. To maximize the value, we maintained Latitude's legendary C-Series legacy keeping it fully compatible with the entire C-series family of media modules, batteries, and docking solutions. Dell Notebooks are the #1 choice of professionals worldwide, and the C600 series is our most popular offering. If you need a notebook that's designed for maximum performance on the road, you will find the C640 a perfect fit.
High Performance with the Latest Mobile Intel Pentium 4 Processor-M and new Intel 845MP chipset
The C640 uses Mobile Intel Pentium 4 processors-M at 1.60, 1.80 & 2.00GHz and the new Intel 845MP chipset. The new chipset supports a 400MHz Processor System Bus (PSB) and up to 1.0GB of PC2100 Double Data Rate system memory running at 266MHz. Combined with new optional high speed hard disk drives (5400RPM) and larger 66WHr batteries, this notebook brings new performance levels to mobile computing.
Improved graphics and brilliant color displays
The Latitude C640 features an ATI MOBILITY RADEON 7500 graphics engine with 4X AGP, and 32MB of double data rate (DDR) SDRAM video memory. The ATI 7500 chipset delivers outstanding improvements in 3D graphics performance (Up to 110% faster than previous Latitude C610 performance depending on benchmark). Choose from a 14.1" XGA (1024 x 768) TFT LCD or an optional high density 14.1" SXGA+ (1400 x 1050) TFT LCD. C640 also implements a new LCD which allows the user to significantly reduce LCD panel brightness for improved control, privacy, and battery life.
Dell TrueMobileTM Wireless Solutions
The Latitude C640 is wireless ready. Each system has dual integrated antennas, so you work untethered without susceptible external cards or antennas. You can also upgrade to wireless communications anytime in the future with easy to install customer kits.
Fully integrated communications, both wired and wireless.
The C640 features a fully integrated 56K1 V.92 modem and 10/100 Ethernet. An internal MiniPCI slot is designed to exclusively support 802.11 wireless2 technology. This combination allows greater user flexibility as the external PCMCIA slot can support other devices even when maximum communication versatility is required.

Flexibility and comfort

The Dell DualPoint integrated pointing device, which incorporates both a touchpad and a track stick, provides the flexibility of using either device or both at the same time.
