Lenovo"s ThinkPad T Series laptops have a legendary reputation amongst business users or anyone who needs to get serious work done. The 14-inch ThinkPad T440s continues this rich tradition, offering long battery life, strong performance, a best-in-class keyboard and an optional 1080p touch screen, all in a durable, 3.8-pound package. However, with a price of $1,514 ($999 to start), this productivity-centric laptop doesn"t come cheap. Is the ThinkPad T440s worth the investment?

Like other ThinkPad T Series, the T440s is built to take some punishment. An integrated roll cage helps the laptop survive drops and dings while solid hinges allow the screen to bend back 180 degrees, and a spill-resistant keyboard prevents a little water from destroying your system. Lenovo says that the T440s has passed several military standard, or MIL-SPEC, tests, including those for humidity, dust, extreme temperatures and vibrations.

At 13.03 x 8.89 x 0.80 inches and 3.8 pounds, the ThinkPad T440s isn"t the most portable business Ultrabook on the block. Toshiba"s Tecra Z40 (13.3 x 9.3 x 0.8 inches) is no thinner, but is significantly lighter at 3.2 pounds while the last-generation ThinkPad T431s weighs just 3.4 pounds, despite having the same dimensions as the T440s. The ThinkPad T440"s 14-inch touch screen is one of the heaviest parts of the system, as it requires a fair amount of force to lift. The extended battery adds 0.4 pounds to the system and tilts it 0.3 inches off of your desk or lap. However, users can save some heft by purchasing the T440s without a touch screen as the digitizer adds between .1 and .2 pounds.

The 10-point touch screen was extremely responsive to all of our gestures, even allowing us to draw with all fingers on both hands at once in Windows Paint. The T440s is also configurable with 1600 x 900 and 1920 x 1080 nontouch panels.

While it"s fine for conferencing and movie watching, the ThinkPad T440s offers unpleasant music playback. The laptop"s bottom-mounted speakers were loud enough to fill a small room, measuring 81 decibels on our sound test, which is fairly loud, but still a tad below the 84-dB category average. Playback also muffled a bit when the system was pressed against our legs.

Unlike the T431s, which marred the typing experience with a hot palmrest, the T440s stayed cool beneath our wrists, allowing us to achieve a very strong score of 92 words per minute on the Ten Thumbs Typing Tutor test, comfortably above our typical 86 wpm score. The keyboard"s backlight has three settings: off, low and high, with the low setting more than bright enough for a dark room and the high perhaps a bit too bright.

The HD webcam is capable of capturing solid images even in a shadowy area of our office, but even pictures we took of our face in a very bright conference room suffered from a bit of visual noise. Like other ThinkPads, the T440s features dual-array microphones for better conferencing, while Lenovo"s settings app allows you to set the mics to pick up a single voice or many at once.

Unlike the T431s, which had a warm right palmrest that made typing uncomfortable, the ThinkPad T440s stayed pleasantly cool throughout our testing. After streaming a video for 15 minutes, the touchpad measured a cool 81 degrees, the keyboard a chilly 84 degrees and the underside a breezy 88 degrees Fahrenheit. We consider temperatures below 90 degrees imperceptible and those under 95 degrees comfortable.

Thanks to its 1.6-GHz Intel fourth-generation Core i5-4200U processor, 8GB of RAM and 256GB LITE-ON SSD, our configuration of the ThinkPad T440s offered very strong performance that was good enough for demanding productivity work. On PCMark 7, a synthetic benchmark that measures overall performance, the T440s scored an impressive 4,970, well above the 3,445 thin-and-light laptop category average, the Toshiba Tecra Z40"s mark of 2,524 and the T431s" 2,884 score.

With its speedy 256GB SSD, the T440s booted Windows 8 in just 14 seconds, half the 28.4-second category average and a bit less than the ThinkPad T431s (16 seconds). The drive took just 27 seconds to complete the LAPTOP File Transfer test, which involves copying 4.97GB of mixed media files. That"s a rate of 188.5 MBps, more than triple the 57.9 MBps category average and eight times the Tecra Z40 and its 7,200-rpm hard drive. The 13-inch MacBook Pro with Retina Display notched a more impressive 299.4 MBps performing the same test in OS X Mavericks.

The ThinkPad T440s took just 5 minutes and 14 seconds to complete the OpenOffice Spreadsheet Macro Test, where we match 20,000 names with their addresses. That time is more than a minute faster than the 6:21 category average, but almost 30 seconds slower than the Tecra Z40 and its 1.9-GHz Core i5-4300U CPU.

The T440s" integrated Intel HD 4400 graphics chip achieved a modest score of 930 on 3DMark11, a leading synthetic graphics benchmark. That"s a little below the 962 category average, but well above the Toshiba Tecra Z40 (869) and ThinkPad T431s (530).

When we fired up "World of Warcraft" at the T440s" 1920 x 1080 native resolution, the system achieved a not-quite-playable frame rate of 29 fps, which dropped to just 15 fps when we turned up the special effects. Both rates are well below the 66 and 29.9 fps category averages.

With the 3-cell 23.2 watt-hour battery, the T440s lasted 7 hours and 1 minute on the LAPTOP Battery Test, which involves continuous surfing over Wi-Fi on 40 percent brightness. That time is more than 30 minutes longer than the 6:27 category average, but not as lengthy as the Tecra Z40"s runtime of 9:28. (To be fair, though, the Z40 has a much dimmer screen.)

With its high-capacity battery, the ThinkPad T440s lasted an epic 14 hours and 36 minutes, making it one of the longest-lasting laptops we"ve ever tested, Though the the high-capacity pack costs just $5 more on Lenovo.com, it juts 0.5 inches out from the bottom of the laptop and adds 0.4 pounds.

Interestingly, Lenovo does not preload the T440s with Windows 8.1, though downloading the new OS is a free upgrade. A Lenovo rep said the company will not start selling the T440s with Windows 8.1 preloaded until sometime in 2014.

Lenovo backs the ThinkPad T440s with a standard one-year warranty on parts and labor. You can extend the warranty up to 4 years and add accidental damage protection or on-site service for prices ranging from $59 to $489.

Our review unit of the ThinkPad T440s carries an MSRP of $1,514. For that price, you get the Intel Core i5-4200U CPU, 8 GB of RAM, a 256GB SSD, Windows 8 Pro and the 1920 x 1080 touch screen. For the starting price of $999, you get the same Core i5-4200U CPU, but just 4GB of RAM, a 1600 x 900 nontouch screen, Windows 8 and a 500GB hard drive with 16GB flash cache.

The ThinkPad T440s is a worthy successor to the ThinkPad T431s. With the performance and power efficiency of Intel"s fourth-generation Core series, long battery life, an industry-leading keyboard and an optional full HD touch screen, the ThinkPad T440s is the new business laptop to beat. Those looking for something that"s more portable than this 3.8-pound system might want to consider Lenovo"s 12.5-inch, 2.8-pound ThinkPad X240. However, if you want the best thin-and-light business system on the market, the ThinkPad T440s should be your top choice.Lenovo ThinkPad T440s: Price Comparison

Hi, I haven’t modded the bios yet. I haven’t had the need to. I think there is not enough space to clamp the clip, you need to remove the entire backpanel.

You got a pretty good deal on the CPU! Most Haswell mobile CPUs are well overpriced on Ebay from my opinion: they range from 100€ to 150+€! Overall mine costed me a bit more: 500€ for the laptop with 4712MQ, 16GB RAM, 500GB SSD, FHD IPS Panel (LG). I upgraded it with: T450 trackpad (35€), azerty keyboard (38€), TP-Link Nano Wifi (8€), hdd bay (6€). That’s about 560€ for the upgraded laptop, after selling replaced parts.

I got a T440p with the i7-4600M and 16GB of Ram for a total of 115. No SSD/HDD and there’s some slightly more white spots on the screen (they don’t actually bother me).I just ordered a 128GB SSD for 25 euro and a B140HAN01.3 for 50 euro (from China). Had the guy make me several pictures and confirm that he’ll be sending an exact model and not a copy or compatible panel (really wasn’t too sure he understood what I was saying).

Hi Ragnar, This is pretty usual. Most T440p come with the TN 1366x768 14 inches panel. It seems like this panel doesn’t age very well. I have bought multiple t440p with worn out displays: I don’t really care since I immediately replace it with the FullHD one.

Make sure to ask the seller if it’s a genuine LCD panel (and not a compatible one). Ask them which LCD they have in stock (if any). Don’t buy any compatible LCD as those are generally of poorer quality. I bought mine on Aliexpress but got one with several dead pixels, so I wouldn’t recommend the seller which I bought the unit from.

I have a T440s that I purchased in 2014. The only upgrade I’ve done so far is a Samsung 1TB SSD. That alone made a huge difference. I am also considering upgrading the original 1600x900 screen to a 1920x1080. However, I am wondering how much of the details you have written about for the T440p can be applied to the T440s that I have. Also, I have an i5 and was thinking about upgrading to an i7. Would your instructions/recommendations apply to my laptop as well?

Hi Roger, I don’t really know the T440s, however it seems quite different because it relies on a ULV Intel CPU. The chassis is also a bit different (thinner). You can’t swap the CPU of a T440s, but you can definitely swap the LCD panel. However, the screens suitable for the T440s might be different. I suggest you to ask on Reddit Thinkpads. It’s the single most valuable resource regarding Thinkpads.

Hi Lars, Thanks for the info! The BOE NV140FHM-N41 seems to have only 262K colors, which should position it at 42% sRGB coverage. With a max power consumption of 4.1W (vs 4.6W for the LG panel), it’s less power hungry.

It seems like this panel equips the Lenovo Yoga 510. I wouldn’t recommend it as it has a PWM frequency of 350Hz (screen flickering) which may result in eye strain. On the other side, the LG panel has a PWM frequency of 21370Hz (see Razor Blade 2017 Review).

I talked to a redditor that said : “the NE140FHM-N61. It should be the best FHD panel for this laptop for now since it’s the low power 400 nits T490 panel.”

Hi Lars, according to Lenovo T490 review on notebookcheck, this panel has PWM too (2427Hz). While it provides an excellent color coverage (92.2% of sRGB), the response time is between 44ms (black to white) and 71ms (grey to grey).

Thanks for the extensive review. I am on the lookout for building a T440P. The only thing that is not clear to me is which screen is considered the best so I would like your thought on this. Could you also elaborate on this: “Always make sure the item description doesn’t talk about compatible LCD”.If you could send me some links that would be great. Thank you!

Hi Jim, Just make sure you get the advertised panel, not a “compatible” one. Compatible LCD panels are equivalent to branded LCD but have usually lesser quality (lower color coverage, higher response time). Definitely not worth the money when you spend a lot to get a genuine LG panel and receive a cheap chinese copy instead.

I notice that a few of the cheapest panels list themselves as being made by AU Optronics but I have a feeling they aren’t. If they were, then they wouldn’t be so coy about showing the labels on the back of the screens.

I have been looking everywhere to buy a replacement screen LG LP140WF3-SPD1 on places like ebay, alibaba, aliexpress, even contacted some suppliers on “panelook.com” but all I could found were compatible screens. Could you please provide me with some websites I could look into? Or maybe even specific listings? That would be a huge help.

1080p LCD: I had a B140HAN01.3 in a T430s before and found it a little dull, not bright enough. So I gave a try to the Innolux N140HCG-GQ2 rev.B1. VERY happy with the Innolux 400cdm brightness. Almost no color adjustments. BUT this Innolux does not have tabs on the rim, no way to screw it in place. My work around: (this Innolux is a lot slimmer) took the metal rim from a broken screen, did some trimming at the bottom, put 3M dbl-side tape on the rim, screwed the rim in place, and aligned the Innolux onto the rim. (Innolux is a few mm less wide than original lcd) Put back the bezel. There is light gap between the bezel and the front of the LCD, which I could get rid off by adding some shimming between the tabs and the top cover… but I did not bother… gap is not noticeable. I’m really satisfied with the screen and the installation.

i7-4800MQ CPU: from a duo to a quad-core… obviously noticeable. But I am a bit disapointed with video encoding. It does take half the encoding time compared with a T440s 2-core i7 CPU. But it is not using the full capacity of the CPU, because of the 45W limitation. Let me elaborate: the 4800MQ, according to hwinfo, based at 2700MHz, turbo 3700MHz (but only for short time)… while encoding video, it tops at 2700MHz, @ 0.9V, 83C, because it exceeds power limit. Which is not the case with a 2-core i7. I have not yet fiddled with undervoltage, nor anything else, YET! So… my point here, is that, in my context, I doubt that a higher CPU (like a 4900MQ) would make a difference… moreover, I bet that a 4700MQ would give the same results (and be a little bit cheaper)

Can you tell me a bit more about the solution you did to ameliorate the space between the lcd and the bezel? I also have the same problem on the bottom part of my bezel. I suspect I might have damaged a plastic connector from the bezel that is not able to stay in place when I put it back together.

It has a resolution of 1600x900, which is OK but I am considering upgrading to FHD. I tried to follow your advice and find a genuine panel (AUO or LG) but the only option I found is through the Lenovo website for >$300. I can’t spend that much.

I was wondering if you (or anyone else) knows where to find genuine panels (I have contacted sellers on eBay, aliexpress, etc but they all carry the “compatible” panels). Alternatively, do you know if the quality of compatible panels has increased since you first wrote this?

Can someone plug in an external monitor into the VGA port and tell me if you can see the bios & OS in both the internal LCD and external VGA monitor at all times ?

I’ve bought mine for about $115 with a 4300M CPU, 1600x900 screen and no RAM or HDD (It was the cheapest working T440P that I could find for sale in my country, and I’ve had 16GB of 1600MHz RAM and a 240GB SSD laying around, so didn’t really care about the lack of these components). I’ve found an incredibly good deal - a synaptics T450 touchpad for $12 and I’ve bought this display: https://www.amazon.de/FTDLCD%C2%AE-N140HCE-EN1-REV-C2-Display-Bildschirm/dp/B07GFF375V/

I am currently running an 860 EVO 1TB SSD in SATA bay, kept the disc bay since it comes in handy at my place of work. 16 GB of RAM (samsung 1600 Mhz - the price on Amazon was very fair), 4702MQ CPU, Synaptics Thouchpad and the FHD LG IPS panel.

For anyone ebay trolling, I got an authetic B140HAN01.4 from seller lcdbeststore - I actually ordered a LP140WF3-SPD1 LP140WF3 so not really what I ordered, but it works fine and is in good condition (seems as good as new). Glossy. Linux confirms:

This is not an endorsement, just stating facts of my experience. Really not digging the 3rd party lcd screen seller drama, that’s for sure. Just happy to have a decent screen even if it’s not the one I ordered.
