Lenovo ThinkPad T420 – Review
Source: Gadgetmix English
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
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
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.

Above all, this display size is used for subnotebooks, ultrabooks and convertibles. For all three types, this size is quite large. The biggest variety of subnotebooks is represented with this size.

Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.

Usually subnotebooks, ultrabooks and quite lightweight laptops with 12-16 inch display-diagonal weigh as much.
