What is the difference between t430s and t430u

Definitelyw the best laptop ive ever owned. Hoping to have a similar experience with my next laptop. Couple of points of clarification All have one GB dedicated memory. If the T was perfect for you and you just want new HW in a similar footprint and form factor as has been stated the T is the only option as it is the best in the lineup for price to performance. The only reason to start to consider other options if you sought to improve your experience in some area That doesn't appear to be the case here In fact, with your initial post I don't know why you're considering moving on I have three T61's and a T61p in my household that are still functioning as new The only reason I have new ones is that they have serviceable lives at work and are replaced accordingly.

I am in the sciences as an undergrad and my winning combination is a T on the dock at my apartment and an XT I carry to campus. The XT is perfect for scribbling everything from synthesis reactions, analyzing NMR results, to doing actual typing on. If I need a bigger screen I have a 23" Samsung monitor as well.

The T I have is one that has a 2. I received it pretty much vacant of components but I have lovingly nursed it back to health. I love it! I purchased the XT in near-excellent shape but it did not have a hard drive, battery, or stylus. Do you purchase ultrabooks as business laptops? What are your business laptop models?

They are beautiful devices but I sure would like a touch screen. Jason Jan 29, at UTC. Steve work This person is a verified professional. Graham Jan 29, at UTC. Fortunately, useless demo version activation popups will hardly distract the user.

The manufacturer instead preinstalls handy tools like Lenovo Solution Center, which facilitates creating backups and provides warranty information among other things. Compared with ultrabook standards, the ThinkPad is quite easy to upgrade. The base plate can be removed without a screwdriver and allows the user to access the hard disk, battery and CPU fan.

The keyboard also has to be removed for this, which Lenovo describes in detailed step-by-step instructions. We did not do this and only want to refer to the corresponding document here. Some manufacturers can take Lenovo as an example in terms of warranty policy. The buyer receives a month on-site service ex-factory. However, you have to dig deep in your pocket for longer periods. As in all newer ThinkPads, Lenovo also installs a spill-proof chiclet keyboard into the Tu which will certainly not appeal to every regular customer right away.

We can however reassure you that the keyboard has not sacrificed any of its qualities with this modification. Nevertheless, users changing from other manufacturers first have to get used to the somewhat different layout, where for example the FN and CRTL key are swapped. When this short familiarization period is overcome, the keyboard presents itself from its best side.

The pressure point is comparatively firm and agreeably crisp and slightly resembles a high-end, mechanical desktop keyboard. This impression is underlined by its muffled noise that pleasantly stands out from the cheap clattering produced by some contenders. The convenient ThinkLight allows for easy usability in the dark, though the notebook does not feature a dedicated keyboard backlight.

Many ThinkPad fans will prefer the traditional TrackPoint to the touchpad. Is this justified? Well, it is partly a matter of taste. In any case, Lenovo has again done an excellent job with the technical implementation.

Regardless of the applied force, the cursor's speed can be controlled very precisely with the small, red joystick. The corresponding, fairly soft clicking mouse keys are located below the space bar as usual. Naturally, the aforementioned touchpad is also available as an alternative. It features an adequate size of 9. The surface now exhibits a finer texture than in former models, but it still pleases with excellent precision.

Rather than using dedicated mouse buttons, clicks are performed via pressing the corresponding corner on the touchpad, which is also known as ClickPad design. We would appreciate a slightly firmer pressure point and a shorter key drop. Like in Dell's and Fujitsu's contenders, the Tu's screen also has a resolution of only x pixels.

This is doubtlessly a low rate at a time when even some smartphones achieve a similar resolution. However, it is still standard in laptops in this price range. Alongside the The ThinkPad also achieves only medial screen brightness rates. The screen is at least bright enough for indoor use. The measured black value of 0.

However, we see a similar performance from the direct contenders. Nevertheless, it would be appreciated if Lenovo would offer a screen with higher resolution and richer contrast for a surcharge - preferably an IPS screen. If you are considering using the Tu for professional purposes, you should fall back on an external monitor.

The integrated screen only covers 57 percent of the sRGB standard , which is usually too little for graphic designers. The color spectrum and accuracy is however absolutely sufficient for occasionally looking at vacation pictures, watching movies or playing a game. The compact size predestines the Tu for mobile use. One of the most important requirements is however that the content can be read outdoors without restrictions. This is unfortunately only possible in the shade with our test device.

Although the surface is AR-coated , the brightness is not high enough to outshine direct sunlight. The screen exhibits more shortcomings in the viewing angle assessment, revealing the known weaknesses of other TN screens. The image quality wanes especially when looking from above or below and results in distorted colors and a decreasing contrast ratio. Although this has a positive effect on power consumption and temperature development, it also results in a performance loss.

Our configuration is powered by a midrange Core iU that features two computing cores with a default clock of 1. As usual, further details can be found in our CPU database.

While most business laptops rely only on integrated graphic solutions, Lenovo additionally equips a few Tu models with a GeForce GT M. Thus, only the efficient HD Graphics is enabled for video acceleration or undemanding tasks.

In return, the GB SSD is particularly noteworthy since it promises short booting times and a very responsive system. The cooling is not always designed for ensuring the maximum Turbo speed during longer CPU full load, particularly in compact ultrabooks.

Here, we have to compliment Lenovo. The Core iU in the Tu stably maintains its maximum clock of 2. This is reflected in good benchmark scores. The ThinkPad achieved 2.

The much more expensive Core iU can only surpass this by 15 percent. The differences in the Cinebench R10 bit single thread test are equally slim. Our test device achieved points here. In our opinion, the iU is the perfect compromise of price, performance and power consumption. A fast storage device that makes loading programs and booting times is more important than the processor's performance in many situations. The controller designed by Toshiba excels with extremely high transfer rates.

However, this difference will hardly be noticed in practical use. The PCMark range only has a limited validity since it is a pure synthetic benchmark anyway. Therefore, we would like to briefly report about our subjective practical experience. We could hardly complain about not having enough power during our tests.

The ULV processor easily coped with all routine applications and offered enough reserves to even occasionally deal with demanding tasks such as video transcoding.

The fewest users will likely yearn for an even faster quad-core CPU. More impressive was the speed of the storage device. Windows 8 was ready to go in 10 seconds after a cold start and many programs started within fractions of a second - SSD power makes it possible.

It is based on the GF chip built in a 28 nanometer process, which integrates 96 Shader units Fermi architecture. The gaming performance of a business laptop like the Tu is certainly a more secondary issue.

However, the ThinkPad is quite suitable to render most up-to-date games smoothly, providing the user makes compromises in resolution and details. The ultrabook even provided playable frame rates in the screen's native resolution and high settings for Diablo 3 and Dishonored.

Even anti-aliasing can be enabled on a low level to enhance the image quality. Anno and particularly Battlefield 3 have much higher requirements on the GT M and consequently, only x pixels and low or medium details should be selected.

In contrast to contenders featuring an integrated graphics, it is a clear improvement. Lenovo has created an extremely quiet ultrabook with the ThinkPad Tu in almost every operating state. Although the fan is never completely disabled even at idle , the low noise level of The device is virtually silent in most surroundings.

The fan stably maintains its low speed in routine use with office programs, Internet browsing and similar applications. The noise increases during long CPU or graphics-heavy software use. We ascertained a rate of Some laptops have already achieved higher rates in idle operation. The fan's low-pitched frequency and steady noise contribute to this and ensures that the ThinkPad remains in the background acoustically.
