At first glance, the T450s looks identical to the previous-generation ThinkPad T440s thanks to the fact that Lenovo used the same chassis. While it might lose points for originality, this Ultrabook retains the same ¡°all business¡± design, road-tested dependability, and is still compatible with all the same docking stations and accessories that your company purchased for your previous ThinkPad. asus u47a battery Good luck finding enough USB-C adapters next month for everyone who buys the new MacBook.Like its predecessor, the ThinkPad T450s is wrapped in a matte black chassis made from satellite-grade carbon fiber similar to what is used for the latest F1 race cars. This carbon fiber is not only more shock absorbent than aluminum alloy but tips the scales at just 30% of the weight of aluminum with a similar thickness.The screen lid is supported by an internal roll cage and square pin stainless steel hinges that anchor the screen lid to the chassis. venue 8 pro charger The keyboard also has a drain to help it survive spills or a brief amount of time outdoors in the rain.As with all T series ThinkPads, the T450s is Mil-SPEC 810G tested for a wide range of environmental hazards from humidity and extreme temperatures to exposure to sand, high vibration, mechanical shock, and even fungus (for users with poor hygiene).Our touchscreen version of the T450s weighs 3.8 pounds with the standard 3-cell removable battery and measures 13 x 8.9 x 0.83 inches. This makes the T450s portable enough to carry between meetings or bring it to and from work each day in a laptop bag. The base configuration of the ThinkPad T450s with non-touch screen weighs just 3.5 pounds with the 3-cell removable battery (3.9 pounds with the optional 6-cell battery).asus x200ca battery The bottom of the ThinkPad T450s can be removed for service and repair after removing 10 Philips screws on the underside of the chassis. Inside, you'll find a single RAM slot, space for a 2.5-inch SATA drive (7mm thickness), the internal 3-cell battery, a single cooling fan, a Wi-Fi module, and an open slot for a WWAN card or M.2 SSD. Of course, most workplace users will forgo disassembling the T450s and simply connect a docking station to the port on the bottom of the notebook if they want to add storage.
Keyboard
If typing comfort and speed are important to you, there is no better choice than the ThinkPad T450s, which has the best laptop keyboard money can buy. It's even better than many other ThinkPads. ux31e charger With 1.9mm of travel and 63 grams of actuation force (55-60 is typical), the keys have a strong tactile feel that makes typing incredibly comfortable and accurate. Almost as good is the subtle indentation in the keys themselves, which makes it easy to feel your way around and avoid adjacent-key errors.Because of the fantastic key feel, I achieved a rate of 96 words per minute on the Ten Thumbs Typing Test, matching the highest score I've ever gotten and well above the 80 to 86 wpm I usually score on other laptops. dell m3800 power adapter The keyboard comes standard with a two-mode backlight, which was more than bright enough on its lower setting and even more powerful on the higher one.
Display
With a 14.1-inch panel, there is plenty of screen real estate to be productive, and opening multiple windows doesn't feel claustrophobic.However, Lenovo only offers a middling resolution on the T450s, with a maximum of 1,920 x 1,080 pixels. acer iconia w510 w511 charger I would like to have seen at least a QHD option on the T450s, as Lenovo offers a 3K panel on the 15.5-inch W550s.On the full HD, LCD touchscreen model, Lenovo claims a brightness of 300 nits. The screen has a matte coating to reduce glare, but I found that brightness suffers slightly compared to glossy panels, like the 300-nit-rated screen on Samsung's Series 5 550 Chromebook.With ambient indoor lighting at work and at home, samsung n8020 genuine charger I usually have the display at around 70% brightness for comfortable viewing. Outdoor viewing is decent under shade with brightness turned all the way up. In general, you shouldn't have any issues with the screen brightness unless you're working in the field under direct sunlight.I found Lenovo's choice for a matte display helps reduce reflections and cuts down glare under bright lighting or outdoors, but the downside is that the coating makes the screen appear dull. charger for g75vx Compared to the glossy display of the MacBook Pro, colors pop less on the matte display found on the T450s.Another downside I found in my testing is that the matte display doesn't look as sharp as a glossy one, with text and images appearing grainier. There is also some light bleed at the edges around the top right and bottom left corners on the review unit. That said, the bleed is only noticeable when viewing a dark image.The 180-degree hinge allows the screen to lay flat for office collaboration, and the IPS display technology helps with wider horizontal and vertical viewing angles.
Screen and Speakers
The full HD multitouch display in our review unit provides a nice 1920 x 1080 resolution with sharp details, good color accuracy and plenty of contrast. The touchscreen surface is accurate and supports 10-point multitouch gestures.charger sgpt111gb s The FHD touchscreen option shown here is an IPS display panel that delivers wide viewing angles out to 60 degrees or more but the lower-priced 1600 x 900 screen is a TN panel with limited viewing angles and reduced color accuracy as your view moves off center.The backlight was relatively uniform but we noticed minor light bleeding near the extreme upper left and lower right corners of our display. We used a light meter to measure the screen brightness in our review unit at an average of 256 nits with a minor hot spot in the upper right corner that measured 278 nits. We consider that "average" screen brightness and it means you'll have some trouble using the T450s outdoors under bright sunlight.The stereo speakers inside the ThinkPad T450s produce adequate sound that is relatively free of distortions and loud enough to fill a large office. samsung np900x4c charger Lenovo uses Dolby Digital Plus audio processing software to improve audio playback and it works; if you disable the Dolby software while streaming Netflix you'll notice an immediate difference in the sound quality.
Performance
The base model ThinkPad T450s starts at just $881 at the time of this writing and is powered by the Intel Core i5-5200U CPU running at 2.2 GHz, 4 GB of RAM, a 500 GB hard drive, Windows 8.1, and a 1600 x 900 screen without multitouch.Our review unit of the T450s is a much more expensive configuration priced at almost $1,600. Paying almost twice as much as the base model gets you the 2.3 GHz Intel Core i5-5300U processor (not much of an improvement over the base model), 8 GB of RAM, a much faster 256 GB SSD, Windows 8.1 Pro, and a 1080p touchscreenlenovo m72e tiny power supply Our test configuration was more than powerful enough to handle typical workplace productivity tasks ¡ but so is the base configuration. That being said, even our "high-end" configuration of the T450s is notably slower when performing processor-intense tasks than T-series notebooks equipped with the Core i7-5600U processor.The saving grace of our review unit is the reasonably quick 256 GB Toshiba SSD. While this solid state drive won't win any awards for being the fastest, it's notably faster than the 500 GB hard drive in the base model and helps improve Windows boot time while also allowing you to install and launch applications faster. alienware m15x battery As you know by now, the ThinkPad T450s is a business laptop and not a gaming notebook. That said, the integrated Intel HD Graphics 5500 is good enough for casual gaming and the kind of general video transcoding you might need to do when uploading a promotional video to a corporate YouTube account. If you want better graphics performance in a business laptop you'll typically need to move to a mobile workstation.
Case
Lenovo has already only carefully changed the design and build of the T400 series in the past. It even appears that they did not change anything in this generation: Weight and size are almost the same as the T440s' and it does not look different, either. At a first glance, the functional design might have the dubious charm of plain plastic, but the case is based on a high-end light metal skeleton made from aluminum and magnesium. The lid was even reinforced by carbon fibers.As a result, the T450s belongs to the stablest devices of its class. Localized pressure and twisting attempts do not have an effect on base unit and display, although we would not have expected this from the delicate ultrabook at first. yoga 3 pro power adapter In addition, the ThinkPad should be able to withstand other environmental hazards like temperature and air pressure changes, vibrations, moisture, or dust, which has been tested to military standards according to Lenovo. However, many competitors also lure buyers with this.We are especially delighted by the functionality of the case, which you will only gradually discover during everyday usage. For example, the smooth surface is very resistant against fingerprints and scratches. asus t100ta charger In contrast to soft touch surfaces, dust can be easily removed. Extremely flexible metal hinges allow opening the display by above 180 degrees. The manufacturer optimized the resistance in such a way that the lid neither wobbles nor the base unit lifts up when the laptop is opened. We did not find any workmanship flaws, at least not in our test model.
Battery Life
If you want enough juice to make it through an international flight (with Wi-Fi on), get the ThinkPad T450s, pop in Lenovo's high-capacity battery and prepare yourself for epic endurance. With the six-cell battery attached, our T450s with touch screen lasted a strong 15 hours and 26 minutes That's long enough to fly from New York to Taiwan and more than double the 6-hour and 8-minute thin-and-light notebook category average.vaio pro 13 battery sheet That 15:26 time is also more than three hours longer than the MacBook Pro 13-inch's time (12:04) and nearly double the ThinkPad X1 Carbon's time of 8 hours. Thanks to its power-efficient fifth generation (Broadwell) Core i5 CPU, the T450s even improved on the T440s (12:37) by nearly 3 hours.q400a battery Considering that touch screens drain a lot more power than regular displays, the nontouch configuration of the T450s is likely to last several hours longer.With the standard three-cell battery, the T450s lasted a more-pedestrian 7 hours and 31 minutes. However, you can purchase the six-cell version, which is the same exact battery used by the T440s, from e-tailers like Amazon for around $78. Hopefully, Lenovo will start offering this battery as a configuration option soon, just as it did with the T440s.replacement charger samsung series 7 ultrabook In addition to its external battery, the T450s has an internal pack that provides some of its power and allows you to hot swap units without shutting off the machine.
