t440s lcd panel free sample

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.

Reason: Needs a function keys section and the status of hardware components in the hardware table (i.e., entries under "Working?") still need to be populated, preferably by someone who has an actual Lenovo ThinkPad T440s. (Discuss in Talk:Lenovo ThinkPad T440s)

If you have a 1920x1080 FHD panel installed and find that text and UI elements are too small, it may interest you to consider using display scaling to adjust the size of UI elements to your preference. Integer HiDPI scaling is likely too excessive for a display of this resolution and size, so you will want to consider a fractional scaling solution.

Reason: Function keys table needs to be populated. See also Lenovo ThinkPad T450(s)#Function keys; the T440s and T450/T450s will likely have the exact same tables since they have basically the same keyboard. This still needs to be confirmed (for good measure). If so, then one section should link to the other (to avoid needless duplication). (Discuss in Talk:Lenovo ThinkPad T440s)
