dell latitude d420 laptop review

The Dell Latitude D420 is the smallest notebook currently offered by Dell. It is a fusion of the discontinued Dell Latitude D410 (latitude d410 battery )and X1. It combines notable traits from both and offers great portability, Toshiba Laptop Battery,power and versatility. Starting at $1199 it also offers great value featuring an Intel Core Duo ULV processor, 12.1in widescreen LCD, ExpressCard slot, a host of wireless options, and great battery life.


Dell's business-minded Latitude notebooks have always been more about function than form, but the Latitude D420 (latitude d420 battery )manages to pack some decent specs into a package that is both small and attractive, making this ultraportable the smallest laptop Dell currently offers. With almost a full workday's worth of battery life, the Latitude D420 stands up admirably to other similarly configured systems in its price range, such as the Lenovo 3000 V100. The 3.7-pound system has just gotten an upgrade to include Intel's Core Duo processor, and at $1,534, it's a solid choice for both consumers and small business users who need power and portability at the same time.

With almost a full workday's worth of battery life, the Latitude D420 stands up admirably to other similarly configured systems in its price range, Satellite A70, such as the Lenovo 3000 V100. The 3.7-pound system has just gotten an upgrade to include Intel's Core Duo processor, and at $1,534, it's a solid choice for both consumers and small business users who need power and portability at the same time.


Like most laptops of its size, the Latitude D420's wide-aspect 12.1-inch WXGA UltraSharp display has a native resolution of 1,280x800. The small screen at that resolution makes for some potentially hard-to-read text, but we didn't have any trouble with basic Web surfing or word processing. The display's crispness partially makes up for the loss of impact that comes from a smaller display. While not the brightest notebook screen we've seen, it was easy to see in a brightly lit office environment.


The build quality of the Dell D420 is great overall. It feels very solid and the steel hinges are very tight though not as tight as the X1's.Satellite A75, The magnesium alloy casing felt rigid and when pushing the back of the LCD it did not cause LCD distortion. Unlike the X1 which uses the hinges to keep the LCD shut the D420 goes back to the more common latch design.


Another major change was the placement of the battery. On the X1 it was placed to the back of the notebook. This offered a number of advantages. When using the extended 6 cell battery the battery protrudes a little and can be used as a grasp for holding the notebook with one hand. On the D420 (inspiron b120 battery , inspiron b130 battery )the battery is placed in the front. The 9 cell battery sticks out a bit. Unlike the X1 battery the D420 battery does not serve a secondary function. There are some benefits however. I for one like to have my ports in the back and the front placement of the battery enable you to open the LCD with one hand which was very hard to do on the X1.


Aesthetically the D420 is a smaller version of the current line of Dell Latitudes. I prefer the darker, more business-like feel to this laptop however it is nothing to write home about. An interesting difference between the X1 and D420 lie in the placement of the power, hard drive and battery indicators.Tecra 8000, On the X1 they were placed at the bottom of the palm rest. When the LCD was closed the LED were hidden which was rather inconvenient. On the D420 the indicators are on the right hinge which is a small but definite plus.


Even without benchmarks the performance difference was obvious compared to the X1. The D420 (xps m1210 battery)runs everything I throw at it fine including some light gaming. The Core Duo U2500 at 1.2GHz processor is very fast for its clockspeed. In fact, it is comparable if not faster than the Pentium M 2GHz in my Inspiron 710m for everyday computing. I can easily run a virus scan and watch a HD movie (720p) at the same time. The other two options for processor are the Core Duo U2400 at 1.06GHz and the Core Solo U1300 at 1.06GHz. Tecra 8100, The U2400 is a sweet spot for those looking to have a Core Duo system yet also wants the lowest power usage and heat output.


Memory is extremely important in today's computing. The D420 (xps m1330 battery )offers up to 2GB of DDR2-4200 (533mhz). This, however, is an extremely expensive option. 2GB is achieved by using a 2GB stick in addition to the 512MB soldered onto the motherboard. Due to motherboard limitation only 2GB instead of 2.5GB is addressable. A more realistic upgrade is 1.5GB of RAM. This is highly recommended for running this system under Windows Vista due to the integrated GMA950. 1.5GB will cost an extra of around $90 if upgraded aftermarket which is a very reasonable price.


The D420 uses Toshiba's 1.8' hard drives. The spindle speed is 4200rpm. While this is rather slow it is not a huge drag on the system. Hard drive capacities come in 30GB, 60GB, and 80GB. 100GB may be an option soon.


In terms of optical drives the D420 is very similar to the X1. It features no internal optical option but does provide an external D-Bay.Tecra 9000, To some the lack of an internal optical drive is a deal breaker, however it lowers the weight and size of the system significantly. For important discs I use imaging software to copy it onto the hard drive as an ISO. This way I can access these discs even if I don't have the D-Bay on hand. The MediaBase also has an optical drive and with the D-Bay the D420 can be turned into a 3 spindle system.


Unlike the X1 which is dead silent, the D420 (inspiron 1501 battery )is rather loud. In a quiet room the fan is noticeable at medium speed. However it is no where close to being an annoyance. I can work comfortably in the library with the fan on max without being a disturbance. What is an annoyance is the placement of the vent. The vent blows hot air directly at the hands of a right handed user which becomes uncomfortable rather quickly. When the notebook is doing intensive work, the right side of the notebook gets much hotter than the left. However, it is a lot better than the X1 even though the Pentium M ULV on the X1 ran a lot cooler. I tested the temperature of the CPU under load with CoreTemp and it topped out at nearly Tecra 9100,90C while the highest the X1 got was around 70C. Still, working on the D420 (latitude d620 battery )is a lot more comfortable over an extended amount of time than on the X1.


The Dell Latitude D420 (latitude d820 battery )is a great notebook for those who want an ultraportable design without sacrificing computing power. The build quality of this notebook is excellent and the price very competitive. Despite some design flaws, notably the location of the vent and the useless brightness sensor, this notebook excels in its primary function as a business ultraportable. Compared to its predecessor the Dell Latitude X1,Satellite 1900, the D420 (latitude d820 battery )is a great upgrade that will be all ready to handle the demands of newer software and Windows Vista.
