Lenovo ThinkPad T420 – Review
Source: Gadgetmix English Archive.org version
The 14″ Lenovo ThinkPad T420 looks like most of Lenovo’s ThinkPads, emphasising efficiency over aesthetics. The exterior plastic has a dull scratch-resistant surface, tending to resist fingrerprints and smears. Supreme typing experience, stellar graphics performance, a paragon of connectivity, and world-beating endurance, a credit to any business.

Change comes slowly to the venerable ThinkPad T series, but when it does, it’s usually worth waiting for. With Sandy Bridge-grade speed, great battery life, durability features, and other goodies, the ThinkPad T420 is arguably today's best business thin-and-light. (But yes, it’s still basic black.)

80% Lenovo ThinkPad T420 Review: The Best Business Laptop?
Source: Notebookreview.com English Archive.org version
The Lenovo ThinkPad T420 is a well-engineered 14" business notebook. It has the hallmark ThinkPad qualities including great build quality and a superior keyboard. I liked almost everything about it. The anti-glare screen prevents reflections and with a 1600x900 resolution, provides a lot of working space. The keyboard has a highly functional layout and the trackpoint and touchpad are easy to use. All this functionality can be taken to the road thanks to the 10 hours of battery from the optional 9-cell. Bottom line, the ThinkPad T420 isn't just a good business laptop ... the T420 is an excellent choice for business, home, and student use.

80% ThinkPad T420: A Classic Workhorse
Source: PC World English Archive.org version
The T420 is solidly constructed and offers racehorse performance. It's highly configurable with multiple warranty options, as befits a business laptop. Just about every IT person we know swears by the T series--for their clients and themselves. That should tell you everything you need to know about the long-term reliability of these laptops.

Comment

Series: Laptop Mag calls the battery runtime "epic", Notebookreview.com writes 10 hours, no doubt, this smaller than average laptop is made for mobile use. Generally, the screen got good ratings except in the russian site Retera. They gave their T420 model a very bad rating.

NVIDIA NVS 4200M: Business Graphics card that is based on the GeForce GT 520M with special BIOS and drivers for business applications. The clock speeds however can in theory slightly surpass the GT 520M, in the Latitude 6420 however they are at a level of the GT 520M.

Non demanding games should be playable with these graphics cards.

» Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.


Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.  


2620M: Very fast Dual-core processor based on the Sandy Bridge architecture with an integrated graphics card and dual-channel DDR3 memory controller. » Further information can be found in our Comparison of Mobile Processsors.


14.00":

There are hardly any tablets in this display size range anymore. For subnotebooks, on the other hand, it is the standard format.

The advantage of subnotebooks is that the entire laptop can be small and therefore easily portable. The smaller display also has the advantage of requiring less power, which further improves battery life and thus mobility. The disadvantage is that reading texts is more strenuous on the eyes. High resolutions are more likely to be found in standard laptops.

Lenovo: Lenovo ("Le" from English legend, novo (Latin) for new) was founded in 1984 as a Chinese computer trading company. As of 2004, the company was the largest laptop manufacturer in China and, after acquiring IBM's PC division in 2005, the fourth largest in the world. In addition to desktops and notebooks, the company manufactures monitors, projectors, servers, etc, and specializes in developing, manufacturing and marketing consumer electronics, personal computers, software, enterprise solutions and related services.

In 2016, the company ranked first in the world in computer sales. It still held it in 2023 with about 23% global market share. Important product lines are Thinkpad, Legion and Ideapad.

In 2011, it acquired a majority stake in Medion AG, a European computer hardware manufacturer. In 2014, Motorola Mobility was purchased, which gave Lenovo a boost in the smartphone market.


86.5%: This is an above-average rating. Nevertheless, it should not be forgotten that about one fifth of all tested models receive a better rating.
