Lenovo’s T-series ThinkPads are designed to provide mobile Professionals an appealing mixture of performance and durability, wrapped up in the familiar durable ThinkPad design. The slimline 14in. T420s features Sandy Bridge processors and optional dual-mode integrated/discrete images, along with additions (under the banner Enhanced Experience 2.0 for Windows 7) such as quick boot-up and shutdown. Much like ThinkPads, there’s also a veritable arsenal of ThinkVantage Tools that help to keep the machine secure and up-to-date

Small Review of the Lenovo Thinkpad T420 Laptop:

The black-clad T420s seems every inch a Its standout visual attributes being the 14in. 1,600-by-900-pixel screens (that is LED-backlit and pleasingly non-glossy) and the conventional (non-isolation-style) computer keyboard. The T420s can be noticeably slim to get a full-featured business notebook at just 2.1-2.59cm, while the footprint, at 34cm wide by 23cm deep, means it should fit comfortably into most laptop bags. Sturdy construction and a solid two-point screen clasp should keep safe and sound in transit.

There is little bend in the lid section, and the keyboard feels Admirably firm when you’re typing. The machine weighs a very manageable 1.78kg using an optical drive in the modular bay (as in our review unit) and also the 90W power brick is reasonably compact

We have used lots of ‘modern’, MacBook-imitating isolation-style keyboards and a few (including those on Lenovo’s very own ThinkPad Edge series) are perfectly usable. However, given the choice, we would select the traditional ThinkPad computer keyboard, as seen on the T420s, every time. Concerning feel and layout, it simply cannot be beaten, in our opinion. There is no backlight, but you do get the Fn+PgUp-toggled ThinkLight that glows from the surface of the lid to assist you operate in dimly-lit ailments. We used lots of pointing sticks from other vendors but few compare to people out of its inventor. You get three buttons together with the trackpoint (right and left mouse(and scroll), and 2 using the stipple-surfaced touchpad, which includes built-in vertical and horizontal scroll zones. The wrist-rest area has a fingerprint reader on the right-hand side, above the ThinkPad emblem.

Advantages of the Lenovo Thinkpad T420 Laptop:

Our review sample of the ThinkPad T420s was powered by Intel’s Quad-core Core i7-2640Mprocessor running at 2.8GHz (3.5GHz with Turbo Boost), backed by 4GB of DDR3 RAM. As much as 8GB of memory is encouraged, by filling both DIMM slots using 4GB RAM modules. A more affordable Core i5-2520M-based system is also available on Lenovo’s UK net site and you’re able to customise the detailed setup of both versions.

The review unit was outfitted with both integrated and discrete Graphics, in the form of Nvidia’s NVS 4200M GPU with 1GB of dedicated DDR3 video memory and Intel’s CPU-integrated HD Graphics 3000, which could easily control between 64MB and 1,696MB of system memory for its own purposes. The NVS 4200M supports Nvidia’s Optimustechnology, which automatically switches between integrated and discrete graphics according to this workload, maximising battery life by not using a high-power GPU for low-end tasks.

Connectivity choices are exceptional, our inspection Sample not only featuring dual-band Wi-Fi (802.11a/b/g/n) and Bluetooth (3.0), but also HSPA mobile broadband (Ericsson F5521gw). One of the ThinkVantage Tools you’ll find a Mobile Broadband Activate usefulness to set the connection when you insert your SIM. There’s Gigabit Ethernet for wired media also, of course.

Storage comes in the Kind of a Quick, low-power 160GB Intel solid-state drive (SSD). This is an expensive option, and you can specify lower-capacity 128GB SSD for #79.80 (ex. VAT) less, or a 320GB, 7,200rpm hard drive

The left handed side features a USB 2.0 port and a 34mm ExpressCard slot, while the facet is taken up mostly with a modular Ultrabay, fitted with a optical drive in our review unit. If you’d like the full claimed 10-hour battery life, you can replace the optical drive using a second 3-cell Ultrabay for an extra #68.40 (in. VAT) to complement the system’s main 6-cell battery.

Lenovo sets great store by the speed with which The ThinkPad T420s boots into Windows 7, claiming this could be achieved ” in as fast as 10 seconds”. Our review sample did not reveal such eagerness to get Windows going, but booted at a perfectly acceptable 30 seconds on average. It was faster to exit Microsoft’s OS though, taking just under 10 minutes to shut down. Although the graphics subsystem delivers comparatively low WEI scores in comparison to people for processor and primary hard disk (SSD inside this case), keep in mind the relatively undemanding WEI tests will be hitting on the integrated Intel HD Graphics 3000 as opposed to the discrete Nvidia NVS 4200M GPU, which will kick in under Optimus when the graphic going gets rougher. In two weeks of general ‘knowledge worker’ use, we found the T420s admirably receptive.

Lenovo claims “up to 10 hours” of Battery life for your ThinkPad T420s, when armed with all the principal 6-cell Li-ion battery plus another 3-cell Ultrabay battery. We didn’t possess the latter, that is a #57 (ex. VAT) options. To test the machine’s longevity with just the primary battery, we quantified the system’s average electricity consumption under workload and idle requirements, employing a Voltcraft VC940 Plus multimeter. Dividing the resulting statistics to the 6-cell battery’s 44Wh capacity gives us estimates for battery lifetime.


Much of the ThinkPad’s design — and Especially the superb keyboard — is traditional, but it packs lots of Up-to-date specs also: Core i7 CPU, hybrid discrete/integrated images, Solid-state driveway, USB 3.0 plus a high-quality multimedia subsystem. All of this Makes for an expensive notebook but it’s one we’re happy to recommend.
