Review Dell Latitude D420 Notebook


Minimalist. The Dell D420 is one of the smallest and most mobile ...

Compact size and light, Robust and high-quality materials, 4 USB ports, Spacious keyboard, Matt display with good resolution, Very low noise emissions, Passable battery runtime (9 cells battery)

Moderate number of ports (except: USB), Touch pad and track point need familiarization, Vertical stability to the vantage point of the display, Moderate performance, Partly high temperature increase

Music sounds tinny and low. In order to enjoy music, we definitely recommend the use of a headset

Dell Latitude D420 with Core Duo and Windows Vista Review


As a college student portability is extremely important to me. I purchased a Dell Latitude X1 in March 2006 with the intention of carrying it around frequently. The X1 was a great notebook that is extremely light and small. However, the 1.1GHz Pentium...

Fast ; Light weight at 3.0lbs with 4cell battery and 3.2lbs with 6cell ; Good battery life ; Widescreen matte LCD ; Lots of wireless options ; Excellent MediaBase and compatible with Latitude Docks

Runs hot ; A bit noisy with fan running at max ; Slow 4200rpm HDD ; Placement of vent on right side of notebook ; No internal optical drive

The Dell Latitude D420 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...

Dell Latitude D420 Review (pics, specs)


The Dell Latitude D420 is a 12.1 ultra-portable notebook designed to succeed both the Latitude X1 and the Latitude D410. In an effort to simplify its ultramobile product line, Dell has merged several traits from each of these two retired models to...

Light-weight design starting at 3.0 lbs and only 3.2 lbs with flush-mounted 6-cell battery Uncompromising build quality, magnesium-alloy casing, and pleasing aesthetics Wide-aspect screen and compact dimensions Respectable battery life with 6-cell...

Limited CPU clock speeds Slow 4200RPM hard drive options and only lesser capacities available Lack of internal optical drive and reliance on D-Bay Average screen quality with restrictive viewing angles Placement of fan vent on right-hand side

Having used the Dell Latitude D420 for some time now, my impressions have mostly been overwhelmingly positive. Although certain aspects such as the slow 4200RPM hard drive, lack of internal optical drive, and merely satisfactory screen have proven...

Dell Latitude D420 ultraportable


When the Latitude X1 was first introduced, it didn't resemble any of the other models in the Latitude line. In fact, it was a rebranded Samsung laptop that was incompatible with the Latitude line's peripherals, including the docking solution. With the...

Feather-light chassis. Excellent battery life. Integrated EV-DO. Dual pointing devices

The ultra-low-voltage processor is not as powerful as its standard-voltage Core Duo counterparts. External optical-drive component

The Dell Latitude D420 is the convergence of the Latitude X1 and the D410, and with it, you get more battery life and an integrated cellular modem in a system that (unlike the X1) looks and feels like other Latitudes.

Dell Latitude D420 review


The D420's reliable performance, battery life and ability to get online at broadband speeds, with or without a Wi-Fi hotspot, make it one of the best ultra-portable laptops we've ever seen

Compact size and weight ; HSDPA capability ; Fingerprint reader

Very limited 3D-graphics capability

Gaming performance is nothing to write home about. The Latitude D420's integrated graphics adaptor score a paltry 145 in 3DMark 2006, and we didn't even bother running F.E.A.R on it -- it's unplayable. The laptop impressed us with its battery life,...
