DURABILITY AND BATTERY LIFE OF DELL
LATITUDE LAPTOPS
AUGUST 2011
A PRINCIPLED TECHNOLOGIES TEST REPORT
Commissioned by Dell Inc.
When looking for laptops to purchase for your employees, there are many
factors to consider besides excellent performance. System durability and battery life are
critical factors for today’s workers, who are always on the go. Their laptops accompany
them as they move from office to office, go home for the evening, stop by the coffee
shop, and travel using various modes of transportation.
To fit this lifestyle, workers need laptops with high durability and long battery
life for the occasions when an electrical outlet is difficult to come by.
We tested how the Dell Latitude E5420 and E6420 laptops, both of which come
with Microsoft Windows 7 preinstalled, stood up against competitors from HP and
Lenovo. Both Dell laptops withstood three high drops that severely damaged or killed
the other systems after only one fall. The Dell Latitude E5420 and E6420 batteries also
lasted longer than the competition’s batteries, increasing the time workers could use
their systems by as much as 18.2 percent, or an entire hour of working time!
