The ThinkPad T series is a line of laptop computers. Originally developed by IBM, and introduced in 2000, the brand was sold along with the rest of IBM"s consumer computer division to Chinese technology company Lenovo in 2005, who have continued to produce and market succeeding models.

In October 2000, the ThinkPad T20 was upgraded and released as the ThinkPad T21 laptop with the Intel Mobile Pentium III (800 MHz) CPU.1400 × 1050. The hard disk space offered was a 32GB—high for the time.

Announced in March 2003, the ThinkPad T40p represented the first in the T series" "performance" class of laptops.1400 × 1050 resolution, a maximum of 2 GiB PC2100 RAM, and a 60 GB IDE hard disk.T41 and T41p and the T42 and T42p (ATI Mobility 7500, 9600, and FireGL T2), with almost complete parts interchangeability, except for the fan (normal or p-series), keyboard (14.1" or 15"), screen (14.1" or 15"), and screen inverter. The 15-inch T42 and T42p models were offered with an optional 1400 × 1050 or 1600 × 1200 "FlexView" IPS LCD display.

The naming convention for the T Series was changed by Lenovo following the release of the ThinkPad T400 and T500 in July 2008.ThinkPad W Series laptops.Linux compatibility. The T-p lineup later returned as an irregular T##0p line with only T440p, T460p, T470p and T540p models.

The Lenovo ThinkPad 25th anniversary edition was released on Oct. 5, 2017. It was based on the ThinkPad T470, but brought back the classic 7-row keyboard.A485, which officially isn"t part of the T Series, but it uses the same housing and has the same build quality as the T480. It offers a 2nd generation AMD Ryzen Pro processor (namely the 2500U), and because of the AMD platform, it lacks Thunderbolt 3 support, but has USB-C support. The A475 had been similarly released in 2017 as a variation of the T470, but with AMD Carrizo or Bristol Ridge. In 2019 Lenovo officially introduced the AMD CPU in the T Series, and differentiated it with the digit 5 at the end of the model number (i.e. T495). From 2020 onwards, the naming scheme changed again, after the letter "T" comes the screen size in inches, then a Generation number (i.e. T14 Gen 1), just like with the X1 series. There is no more differentiation in model number for the AMD processors.

PCWorld said that the ThinkPad T20 “packs a bigger screen, a more comfortable keyboard, and a larger set of useful features into a smaller package than any of its competitors.”

Ghost Touch, Running Touch, No-Touch, and Inverted Touch are not screen related issues. Kindly check your digitizer board and cable since they are the most likely cause of any touch issue; please do not open a return claiming the touch did not work. If the machine has a weakened or fragile digitizer board, the replacement unit or assembly will not have proper touch or in some cases it may not have touch at all.

I broke my laptop screen a month ago at a rehearsal for an evangelistic event. I was busy transcoding a video so it’d play in ProPresenter, and left a flash drive cover flipped open over the keyboard, and shut the lid…

It turns out that buying an OEM replacement part form Lenovo costs a cool $400 AUD, excluding GST. I think you’d agree with me that this is ridiculous - and this does not even include the labour to do the screen swap.

I really wanted to get an exact same LG screen panel replacement. Especially since I had changed the screen panel 2-3 times already under warranty - the previous AUO panels were rather grainy.

You MUST message the seller to get their word on the actual screen panel they will send you. Most sellers are helpful and will check if your laptop is (electrically) compatible or not.

Unlike AliExpress, eBay + Paypal gives a 100% money back guarantee + no return shipping fee. So my first experience with AliExpress will likely be my last for sourcing LCD screens.

Any mainstream notebook can run popular apps like Microsoft Office, just as any pair of sneakers will protect your feet while you play basketball, but working on the Lenovo ThinkPad T450s feels like running down the court in Air Jordans. Lenovo"s ThinkPad T Series of business laptops has long been known for its first-class combination of long battery life, sharp screens, durable design and best-in-class keyboards. Starting at $881 ($1,592 as tested), the 14-inch T450s takes mobile productivity to the next level with a speedy Intel 5th Generation Core i5 CPU, over 15 hours of potential battery life and the most comfortable typing and navigation experience anywhere.

Lenovo"s notebook uses the same chassis as its predecessor, the ThinkPad T440s, and that"s a good thing. With the T450s" rectangular shape and raven-black lid, sides and bottom, the device has the quiet but classy ThinkPad aesthetic that"s equally at home in the boardroom or the coffee shop. The red TrackPoint pointing stick and its red-striped buttons add small splashes of color. ThinkPad logos with glowing red lights for the dot in the "i" sit on the lid and the deck, blinking to show you when your system is asleep.

Even if you don"t like the ThinkPad T450s" conservative looks, you have to love its durability. With a carbon-fiber lid, magnesium body and interior roll cage, the notebook is designed to take some abuse, passing MIL-SPEC tests for extreme temperatures, humidity, vibration, sand, shocks and fungus. The company also tests the T450s by opening the device"s stainless steel hinges 30,000 times and dropping metal balls on the machine from over a meter in the air. The keyboard also has a drain to help it survive spills.

At 13 x 8.9 x 0.83 inches and 3.8 pounds, the ThinkPad T450s (touch-screen version) isn"t the thinnest or lightest business notebook in its size range, but it was more than svelte enough for me to carry around indoors or bring to work in my laptop bag. If you get a regular display rather than the touch screen our review model came with, your ThinkPad T450s will be just 3.5 pounds. This makes it the same weight as the 13-inch MacBook Pro (12.4 x 8.6 x .71 inches, 3.5 pounds), though a bit larger.

Lenovo"s own ThinkPad X1 Carbon has a 14-inch screen and is significantly thinner and lighter (13 x 8.9 x 0.73 inches, 3.07 pounds), but it costs more, and has shorter battery life and shallower keys. Using the extended battery rather than the default adds 0.4 pounds of weight and 0.3 inches of thickness to the bottom back of the T450s, but getting more than double the battery life will be worth it for many users.

The ThinkPad T450s features dedicated left, right and center buttons for the TrackPoint. This is a huge improvement over the 2013-2014 ThinkPads, which built all three buttons into the top of the clickpad, forcing stick users to move their fingers down further and push with much greater force. Lenovo got some well-deserved criticism for taking dedicated buttons away on the T440s, so the company deserves some credit for listening to its customers and bringing those buttons back on the current model.

If you prefer a more traditional touchpad, the ThinkPad T450s" 3.9 x 2.25-inch clickpad more than fits the bill. It offered smooth navigation around the desktop in my tests while accurately registering multi-touch gestures such as pinch-to-zoom, two-finger rotate and four-finger swipe for showing the task manager. Many gestures, including Windows 8"s swipe to change apps, were disabled by default, but after visiting the Advanced Settings in Control Panel, I was able to turn them all on. I also found that it was easier to move my pointer across the screen in one motion after turning the speed of the touchpad up a couple of notches.

The T450s" display managed to produce 100.8 percent of the sRGB gamut on our color test, which means that it can show significantly more shades than the average notebook in its category (76.6 percent), the X1 Carbon (86 percent) and the MacBook Pro (91 percent). Its colors are reasonably accurate, as it returned a Delta e error rate of 3.9 (0 is perfect), a score that"s decent but not as strong as the MacBook Pro"s 1.2 mark.

At 236 nits on our light meter, the T450s" screen is not as bright as the 242-nit category average, and far below the MacBook Pro"s blinding 389 nits. Viewing angles were solid up to about 60 degrees to the left or right, with some loss of dark shades at more extreme positions. However, the glossy touch screen shows fingerprints quite prominently in black areas.

The screen responded quickly and accurately to all of my touches, whether I was tapping on a tiny window widget or swiping in from the left to switch apps. The digitizer supports 10 points of touch, as I was able to draw with all of my fingers at the same time in Windows Paint and perform multi-touch gestures, such as pinch-to-zoom with ease.

While not quite high fidelity, the ThinkPad T450s"s speakers provide sound that is loud enough to fill a large room and highly accurate. Whether I was playing Mark Ronson"s drum-centric "Uptown Funk" or Chic"s bass-heavy "Good Times," the audio was good enough to dance to and did not suffer any tinniness or distortion.

The ThinkPad T450s stayed pleasantly cool throughout our tests. After 15 minutes of streaming video at full screen, the touchpad measured just 82 degrees, the keyboard clocked in at a mere 85 degrees and the underside was only 89 degrees Fahrenheit. We consider temperatures below 95 degrees acceptable and those below 90 degrees imperceptible. In other words, you won"t feel any heat under normal circumstances.

The T450s" 720p webcam captured colorful images of my face, which were just a little noisy under the somewhat dim fluorescent lights of our office. In a very dark room, the picture was more pixilated but still vibrant and detailed. Frequent video-conferencers will appreciate the notebook"s dual-array microphones, which can be optimized for either single- or multi-voice conversations.

With its 2.3-GHz Intel Core i5-5300U, 8GB of RAM and 256GB SSD, our configuration of the ThinkPad T450s was more than powerful enough to handle any productivity task. On Geekbench 3, a synthetic benchmark that measures overall performance, the T450s scored 5,993. That"s below the 7,082 thin-and-light notebook category average but on par with similarly specced systems like the ThinkPad X1 Carbon. The MacBook Pro 13-inch and its 2.7-GHz Core i5-5257U were noticeably faster, notching 7,113.

Ideal for office work, the ThinkPad T450s took just 4 minutes and 41 seconds to complete the Laptop Mag Spreadsheet Macro test, which involves matching 20,000 names with their addresses in OpenOffice Calc. That"s a minute faster than the category average (5:41) and 33 seconds quicker than the T440s (5:14). The MacBook Pro fared better, finishing in just 3:28.The more than 15 hours of battery life is enough juice to fly from New York to Taiwan.

Because of its speedy 256GB Toshiba SSD, the T450s finished the Laptop Mag File Transfer test in just 34 seconds. That"s a rate of 149.7 MBps, about 40 percent above the 104.2 MBps category average but not quite as fast as the MacBook Pro, which notched a rate of 386 MBps.

Though nobody would mistake the ThinkPad T450s for a gaming machine, its integrated Intel HD Graphics 5,500 graphics processor is fast enough for casual gaming and serious productivity. The notebook scored 59,843 on 3DMark Ice Storm Unlimited, a synthetic benchmark that measures graphics. That number is slightly behind the 65,420 category average, but many products in the thin-and-light category are designed with discrete graphics.

When we fired up a game of World of Warcraft, the T450s achieved a highly playable rate of 36 fps in 1080p resolution at the default settings, much better than the MacBook Pro (24 fps). When we turned the special effects up, that rate dropped to a slide-show-like 14 fps, which was actually a little less than the also-weak MacBook Pro (17 fps).

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. 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.

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.

Our review configuration of the Lenovo ThinkPad T450s carries a current street price of $1,592.10. For that price, you get the notebook with a Core i5-5300U CPU, 8GB of RAM, a 256GB SSD, Windows 8.1 Pro and a 1080p touch screen. Lenovo lets you configure the system to order, and you can save a lot of money by choosing more affordable options. The touch screen alone adds $310 over the base price.

The base model ThinkPad T450s costs a very reasonable $881 and comes with a 2.2-GHz Core i5-5200U CPU, 4GB of RAM, a 500GB hard drive, Windows 8.1 non-Pro and a 1,600 x 900 nontouch screen.

To get the best mix of price and features, we recommend configuring the T450s with a 1080p nontouch screen ($70), which will give you a sharp picture, along with longer battery life and a lighter chassis. Go with the 2.2-GHz Core i5-5200U CPU that isn"t much slower than the Core i5-5300U on our review system, but costs $100 less. If you can live with less internal storage, the 128GB SSD is a $90 premium versus $280 for the 256GB model. If and when the six-cell rear battery is available as an option, it"s worth every penny; on the T440s, it was only a $5 premium.

The T450s also comes with Pokki Start Menu, a third-party app that sits in the taskbar and launches its own "Start menu" without actually replacing or enhancing the actual Windows 8.1 Start button. A lot of the options in Pokki"s software lead you to the company"s app store, which makes the whole menu feel more like a promotion than a useful utility. Windows 8.1 users who want a useful Start menu replacement have a lot of other options, including Classic Shell, which is a free download.

Lenovo backs the ThinkPad T450s with a standard one-year warranty on parts and labor. You can buy an extended warranty that goes up to four years or add on on-site service and accidental damage protection, with prices ranging from $39 up to $399.

Even if you"re not buying it for business, the ThinkPad T450s is the best notebook for getting work done. You can find other laptops with solid performance and high-res screens in the $850+ price range, but the T450s stands head and shoulders above the crowd with its best-in-the industry keyboard, durable chassis and epic battery life.

If you"re looking for more portability and are willing to accept less battery life and keyboard comfort, the ThinkPad X1 Carbon is a strong choice. If you want more performance and a brighter display, the MacBook Pro should be near the top of your list. However, if you"re looking for the ultimate combination of productivity and portability, the ThinkPad T450s is your best option.Lenovo ThinkPad T450s: Price Comparison
