T440p Owner's Thread

Update drivers, upgrade to Win 8.1, make sure you're using the power saver mode, and don't stay on 90% screen brightness. I generally sit at around 30-40%, and right now my battery is at 62% and is claiming to have another 4 hours of battery (though I doubt that's extremely accurate)

 

Along with update drivers, make sure you install this


Intel Collaborative Processor Performance Control (CPPC) Driver

from here: t440p driver page

 

My fan still makes a horrific grinding noise. The funny thing is that I don't remember it doing so out of the box, so it must have manifested in the first hour or two of runtime.

I'm going to have to send it in for service on the fan at some point, but I can't go without a laptop for three weeks or more during the school term. I'll probably wait for an opportune time and see if I can sneak in an LG->AUO screen replacement as well.


My laptop has otherwise been stellar, even the LG screen is miles ahead of my next best monitor and in fan0 the laptop is completely silent (which is good because capacitor whine drives me insane). Having a mangled fan is pretty annoying but at least it will be an easy swap. All the rest of my nitpicks are small things like the brightness of the lights (IMO all laptops should tie every LED brightness to the monitor brightness) and the trackpoint redesign. I find that I use the trackpoint a lot less on my T440p, compared to the T410s.

 

Interesting. Slide 15 of http://www2.partnerinfo.lenovo.com/...hinkpad-tseries/T440p Sales Presentation.pptx mentions "9 Hours – Go All Day, 20X reduction in idle, >10 days connected standby" but it doesn't quote a specification.

 

I have a i7-4800MQ with a Samsung 840 Pro SSD (single drive) with Win 8.1 and the report says:

CONNECTED STANDBY Not supported

 

You seem to be experiencing the same issues as me. I too, did not notice the nasty fan at first - so indeed it may have manifested after a bit of use. This seems to be the case with my CPU whine as well. Any idea if this is specific to the CPU, or other components on the mainboard?

Here is an expert from the review on the notebookcheck review, whose unit too had a horribly noisy once it initiates..

Full review: http://www.notebookcheck.net/Review-Lenovo-ThinkPad-T440p-20AN-006VGE-Notebook.108423.0.html

So frustrating so many components are causing issues in this new model.

 

I had the fan replaced in my new T440p because it made a grinding/buzzing noise. The new one is virtually silent (aside from the sound of rushing air). The tech took about 10 minutes to replace it.

 

Can everyone let me know what their IPS screens were like? Did you have backlight bleed? I have an x230 and the backlight bleed is pretty bad!

 

All I know about capacitor/inductor whine is that it is horribly annoying and near impossible to track down. I'd probably blame the motherboard/psu circuitry before the CPU but it could really be almost anything.

I have an LG screen and just have a slightly brighter border against the top and lower bezel (viewed in a dark room, maximum brightness, fully black screen). Nothing like any of the pictures in this thread.
I can definitely notice the "spotlight" effect and narrower vertical viewing angles though.

The colors and viewing angles are overall much better than any other laptop I have used before. This is my first IPS screen so I don't really have a benchmark to compare it to.

 

I had an LG display in my T440p that had horrendous backlight bleed. On boot the screen looked like a checkerboard and once logged in there were still 3-4 big patches of light bleed along the top and one side. Had it replaced with an AUO and it is almost bleed free on boot. However, I can induce some bleed along the bottom depending on how I adjust the screen angle. the lid is just too flexible and probably pushes on the LCD panel frame in some cases.

 

UPS said they would deliver it today. I waited all day... Nothing...

Saturday and Sunday of course they're not working, so again I'm stood up and left standing. G-ddammitsonovabishpieceofcrabs#*%&$@*!!!

SERENITY NOW!

 

I talked with a sales rep and they said I can return the unit within 21 days for ANY reason. They will pay the shipping. this convinced me to place an order - I5, IPS panel, 9 Cell battery ... And with huge kudos to Iphetamine I got an extra ~$50 off with student discount. Also thanks to the many owners in this thread I requested a comment be placed on my order AFA panel manuf.
For anyone that paid via amazon credentials (Amazon Chase CC) did it take a few days to post to your account? TIA, Josea

 

This has been my experience with the lg panel as well. It really is a very nice didplay

 

Wrong thread, please delete

 

Wrong thread, duplication, please delete

 

I've decided that the LG panel isn't as bad as a lot of people are saying. My only problem with it is the vertical viewing angles when tilted back, but otherwise it's a pretty decent display with good color reproduction -- I wish it was a few nits brighter but I'll live.

 

Finally received mine. Immediately swapped the HDD for an SSD. The RAM stick was loose (?!), so fixed that.

Having lot's of trouble trying to get the thing to boot from USB-stick. All this secure boot crap turned off, finally let me boot off my sticks. Next thing it does is f-up screen resolution when booting a G-Parted bootable. My Puppy Linux USB-bootable doesn't even gets a proper chance. Trying to install Win7 from a USB stick, stuff starts whining about CD/DVD drivers... I'm not even using that drive!

-edit- Set the USB 3.0 to 'auto', doofus...

Win7 now installing from the stick. Still G-Parted (part of Hiren's boot 15.2+) has f-ed up screen (perhaps can't cope with the IPS screen?). I hope other Linuxes (Kali/Ubuntu) aren't going to be a problem...

Does anyone know where I can get the Win7x64 drivers? The website isn't showing anything when I choose the support page.

-edit2- Trying this link: http://support.lenovo.com/en_NL/downloads/detail.page?DocID=DS038816

That pack of drivers worked. Used 'device manager > update driver' to get the Ethernet port working. Now installing all updates windows has to offer me, hopefully I'm getting the most out of the machine and I'm not skipping drivers here. OSD stuff and such would be really handy when toggling the WIFI option.

Something else: the touchpad is really the worst I ever used... What the f- is this?! I think I need a tutorial for this thing, that's really retarded... I hope it can be more accurate with an update of some sorts, but the way it is now it's useless.

-edit3- Eventually ended up using this http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS037579 to get my drivers from. Now trying to figure out how to turn on the keyboard light...

And I found some kind of hardware failure thingie. When I tilt the screen back it turns off... Fail or feature?

-edit4- After doing this a few times it stopped that behavior and now it's okay... But for how long...?

-edit5- After trying to install Linux it went into a boot-loop. F-ing ridiculous... I think I'm sending this piece of c- back. Seriously, I've never had a piece of c- as big as Lenovo.

-edit6- Taken the SSD out, now it agrees with booting from CD/DVD. I'm going crazy, why not boot from CD when the SSD is in? BIOS has settings the way it should.

-edit7- Made the SSD completely blank, put it back in, bootloop. My relationship with Lenovo ends here, never seen so much trouble with a laptop in my life and I've seen a lot of laptops. I still can't believe this.

-edit8- First I calmed down. Then I took a different M500 SSD and put that one in. Again once it boot looped. Then it booted the USB stick. Put the troublemaking SSD in an external USB bay and formatted it to NTFS. Put that back in. No bootloop, booted to USB. I don't get it anymore. Why the bootloops? I now remember it happened three times after flashing BIOS 1.18, could that be the cause? I thought it was the flashing procedure to reboot a few times... Now I'm not sure anymore. Going to try to install Win 7 again. If anyone has some more info on this strange issue, please let me know. Or let me know what I could possibly do, because I'm losing my cool.

-edit9- I can't stop trying. I guess that f-ing with the MBR on the SSD gets you a first prize, the boot loop. The thing is too darn stupid to know how to handle a simple Grubbed MBR? I'm probably too stupid to fix it the right way. Why won't this thing let me run Linux the proper way? Anyone with an answer to that? I guess I'm calling tech-support tomorrow. I need some sleep, paranoia is telling me the Microsoft Mafia has something to do with this.

-edit10- Jeez, this post is going obese. This time, started from scratch again. First threw all partitions off the 960SSD, let Win7 make itself comfy on install. After installing booted Kali Linux live from USB, used Gparted to create partitions (Primary; /boot and logicals; /, /home and swap). Don't put the grub-stuff in the MBR, for some retarded reason Lenovo doesn't want me to and gives me boot-loop. I put it in /dev/sda3 (location of the /boot partition). I hope this gives helps with trusting this laptop, but we really got off on the wrong foot. Let's see if this method works the way it should...

-edit11- Linux boots just fine. Windows 7 is giving me the finger.



Why?! Perhaps you now know why I'm being so verbally abusive. It's ridiculous!

-edit12- Fixed that by logging in blind, clicking right, choosing 'Screen resolution' option, press TAB twice, a few times up, enter, press TAB four times, enter... Still scrambled screen, reboot, screen normal...

Next thing I tried, installing SP1, normally works like a charm. Error occurred, 0x800F0A12. I'm going to hang myself, someone is f-ing with me...

-edit13- Seriously, this is where my knowledge ends. It's not worth having a nervous breakdown over (I'm really close though), but this craptop really got the best of me. I'm completely done, there's nothing more I can think of. I think I started over about 10-15 times now and still nothing works. I really cant believe what is happening. Without this simple stuff working it's really the worst piece of hardware I ever came across. I give up. Thanks for listening...

-edit14- After some more testing I found that the screen scramble remains even when all correct drivers are installed...



Because of the tilting-back black screen, they were going to send someone over with parts. I said I was unsure if I would want to keep the device. So I'll be thinking that over in the coming days. I can't use a device that is that unstable, nobody can.

 

I've had that problem with Windows 7 -- it has to do with installing from USB. I'd just burn the ISO to a CD if I were you. Here is the workaround, from A required CD/DVD device driver is missing, usb installation - Microsoft Community

 

So I ended up caving in and calling Lenovo again today -- to my surprise they didn't argue when I asked to have my screen replaced! The part is on back order now and I should be hearing from a tech sometime tomorrow. The woman I talked to on the phone (Helen) was very helpful and very patient.

Hopefully the AUO screen is acceptable. I had one for a brief time before I returned my Clevo W740SU and it was honestly pretty fantastic. Wide viewing angles, bright screen, no reflectiveness at all.

I upgraded to the 3 year on site warranty at the time of purchase for the record.

 

Got my machine yesterday ordered on 2/12/13. 3 weeks later than expected. Was not kept up to date on the delays by digital river. UPS details were not up to date and I waited a whole day and it did not arrive. I was put off buying another laptop for a year because of my last bad customer experience with Lenovo. There is no need for it. I don't mind a delay but let me know my chances when I buy. Keep me up to date. Allow me to cancel and get a quick refund if the delays are extended.

I love my old thinkpad's black design but my first reaction to this machine was the plastic feels cheap and slapped together like a budget machine. The lip of the palm rest has a thin sharp edge that makes a really cheap sound when you brush against it. It can cut into the wrists.

It was sly of lenovo to make the laptop seem so slim in the product pictures on the web. I bought the i7-4900QM so I don't mind but if I had bought a machine with a lower specification I would have felt cheated. Although the extra weight and thickness is not as sexy, I find practically it makes no difference to me, I'd rather have the power and ability to change components than the sexy X1.

I got the backlight keyboard. I don't know if this makes the keys feel so loose but they are lacking the comforting bounce of my other thinkpads. Also 2 keys are worse than the others.

The reason I got a backlight was so I could see the function keys in the dark. However they are now multimedia keys. You can swap them but the lights show the media key symbols and I still struggle to distinguish them. Also by swapping the keys I am forced to have to have the fn green led on all the time. Alt-F4 to close windows, F5 to refresh pages, and F11 to maximise the screen, are important buttons I use all the time.

When lying on the bed the backlight of the media/function jumps out from under the keys and shines in my eyes.

I wish the backlight had a red setting, or was programmable like Dell's alienware

This keyboards keys ~ and # are full sized. This was an unexpected disappointment. The enter bar is now an uncomfortable stretch away.

I had the FHD screen with backlight bleeding.

My fan is really noisy.

Phoned warranty support. It was a pleasurable experience. A guy is coming out tomorrow to fix the fan and keyboard. I was lucky to question them about the monitor because they were going to replace my FHD with a HD+. How can I check my monitor details and make sure I get the best replacement.

I vary rarely touch the trackpad and am hating the new mouse button setup. The mechanics of mousepad feel cheap. And the area on the pad for the clicks are so far in the corner I have to stretch my hand more and often mis click it.

The casing of the thinkpads feels less sturdy.

The red light on the i on my thinkpad on the palm rest does not light up. This is a shame because it does not look as cool. Is this by design or do I have a fault.

The light on the power button is of no use to me. Could they not have doubled its function as a charging indicator?

I want the 7th row of function keys back. I wound not use them for touch typing but they come in handy.

I bought the 7200rpm hard drive. It is really noisy. It makes the machine so slow that my 1.6ghz i3 (v2) ran faster than this machine. I swapped it for the 840 pro and it now runs lightning fast.

I bought the i7-4900QM because it had 8m L3 cache hoping it would speed up Dragon NaturallySpeaking. The actual text dictation seems to be a similar speed to my 1.6ghz i3 ( I tried lowering bestmatch to v3). Disappointed I am not getting my moneys worth from the expensive processor. Although it does run Dragon commands like opening programs and changing windows lightning fast compared to i3.

Edit 1: My machine had a power setting of 'balanced' making it run as slow as an intel i5 u non quad processor when on battery. With power setting set to 'performance' it is running faster. Dragon speed is now better than my old computer but I was expecting better results than I am getting.

Edit 2: My microphone was in the USB2 slot. Moved it to USB3 and dragon works a lot smoother.

 

I had a noisy fan (replaced and now silent) and display backlight bleed (screen replaced and now much better). I am also not impressed with the keyboard backlight shining from under the keys (the top row is particularly bad) but I guess that's what we get when we have a keyboard with fairly good key travel.

The "i" only lights up in the logo on the lid, not the palmrest. It would be cool for Lenovo to have the palmrest one also light up as a power/charge indicator, but alas Lenovo is more interested in using us for advertising than actually giving us a useful indicator light

 

@pipspeak Thanks for getting back to me on the red dot

Just did a cinebench r15 test on my cpu. It explains why my machine did not feel faster than my i3 when using some programs.

I had performance set to balanced whilst on battery: my machine got a 'Cinebench R15' cpu benchmark that ranked below an intel i5-3317U

on mains: my cpu benchmark was ranked below an intel i7-3720QM (score was 565)

with power settings set for performance and running on battery: My Cinebench R15 score was 506, ranking it just below this laptop on mains.

 

Dericbytes, your post immediately grabbed my attention. I have mine sitting here on the floor with the same 4900MQ for exactly the same purpose - voice recognition use (Dragon Medical). I haven't fired it up as I am waiting for W7Pro downgrade media to arrive from Lenovo (I ordered it with W8 in a momentary lapse in judgment).

Are you on W8 or W7?

Are you using 6-cell or 9-cell battery?

I presume yours had the compulsory 730m video card as it wasn't optional when you ordered it.

So basically the 4900MQ (in T440p) even when plugged in scores a lower benchmark than 3720QM? Is this replicated anywhere else? I am just curious.

And how is your battery life on "Performance"?

Lastly, has Lenovo fixed your noisy fan?

Thanks in advance.

 

I am using windows 8.1 with a clean install.

I have the 6 cell and 9 cell. I have not really tested them. All I know is that the 6 cell ran from full to empty in 3 hours whilst watching netflix, the first time I tested it. This was on the performance setting of balanced.

Yes I got the 730M. Seems a strange card to offer. The haswell processor is pretty strong and when you need more umph you most probably want something better than the 730M.

The 4900MQ did better in other peoples tests. On this website 3D Fluff Maxon Cinebench 15 Score Results it scored 686. I am going to test again when I upgrade my RAM from 8GB to 16GB am curious to see if that effects it.

Hopefully fan and keyboard will be replaced today.

Noticed I can not get my headphone jack to work today. Even tried installing the old hard drive to see if it was a software problem

@axr: Why don't you want windows 8.1. You can get it to boot straight into desktop. Windows classic shell is a free sourceforge project that returns the start button and adds slight improvements. You can remove most metro apps so they do not accidentally pop up. You can disable the top corners and sides of the screen from prompting access to metro. The core of windows 8 is windows 7 with improvements in speed and functionality. You can still log in using just your local account. The only annoying feature I notice on windows 8.1 now is when I move my mouse to the lower corner of the screens and I get charms bar showing but thats not really an issue.

 

Well, I made my choice, it's being sent back. Called them up this morning and told them I've had it with that piece of #$@%. The guy on the phone had never heard of those problems, I must've had a 'monday-morning-device', bad luck. But he understood I wanted to send it back. Waited f-ing long for it to arrive, such an anti-climax... Now waiting for the money to be refunded, could take as long as two weeks, of course.

Lenovo Thinkpad T440p(roblems) - YouTube

My very short review.

 

That really sucks, but I think you just got a really awful device. Personally I'd say ask for an exchange for a completely rebuilt one rather than getting a refund, but I can understand your frustration.

 

The guy on the phone told me I had bad luck. I asked if it was possible to swap devices, but Lenovo doesn't accept that. So he advised me to be on the lookout for weekend-discounts on the website and just order another one. I'm not sure if I'm going to do that yet. First I need to get rid of this rage.

Perhaps next week I'm confident enough to order a replacement, then I'm giving it the same treatment, let's hope I just had a big patch of bad luck to go through.

 

I was supposed to get fan and keyboard replaced to day. Guy turned up without keyboard. He did not know he was supposed to do it. He phoned office and they said they knew about it but it had not turned up. He needs to come back for the monitor so am not bothered.

Noticed my headphone jack was not working. He tested the jack without checking sound drivers or pc settings. Said machine needs a new motherboard. Not sure if I want to watch him replacing that. He took the keyboard off to replace the fan when he did not need to. I watched him struggle to pull out fan whilst one screw was still in. The keyboard keys are a little worse after he struggled to replace it.

New fan still whines, even when all I am doing is writing. I spent the repair guy a text and he said he will inform lenovo. Some people have said the fan is silent except for gushing air. Is this right? Should there be no whine sound at all?

Grrrrrrrr

Ran Cinebench a few times to test fan and see if it would settle. Got results 565, 590, and 570 for my i7-4900QM. My brothers pcspecialist laptop with i7-4700QM got 608.

 

Will this work in the T440p? I'm not sure how dual voltage RAM works.

Amazon.com: Crucial 8GB Single 8GB DDR3 1600 MT/s (PC3-12800) CL11 SODIMM 204-Pin 1.35V/1.5V Notebook Memory CT102464BF160B: Computers & Accessories

 

I haven't had any issues with my fan. It will occasionally ramp up a bit if I'm doing something intense, but even then it's not very loud. Other than that, it's pretty much silent.

I've gotten really annoyed with Windows 8 and trying to set up dual boot. I'm not sure if it's the computer or just Windows 8 that's causing the problem. I suspect the latter, so I am just going to do a clean install of Windows 7 when I get the time. Currently I can boot into Ubuntu no problem, but when I select Windows in grub it fails.

Also, I haven't gotten the trackpoint buttons working in Linux. The nub works, but the buttons don't. Does anyone have any experience with this?

 

Install Arch Linux and get the xf86-input-evdev-trackpoint drivers from AUR. They work perfectly for me.

I don't think there is any fix for other distributions until the changes reach upstream (if they ever even do)

 

Not to be rude, but this makes me feel very good about shipping mine back to Lenovo while it's still possible. Wouldn't want some guy poking about in my laptop while he's clearly not qualified...

I'm sorry for your trouble though. Let's hope they agree on the broken motherboard, that probably means you're getting a complete replacement.

 

If I don't have time to install Windows 7, I definitely don't have time to install Arch.

But it seems odd to me that it isn't working, because I had absolutely no problems with the trackpoint buttons on a w530. I didn't think they had made significant changes to the trackpoint system between those models.

 

Installing Arch is pretty easy. You partition, mount, pacstrap the root partition, chroot, install grub and reboot. It's actually the fastest install process I've ever done for a Linux distro.

 

Easy to install Arch if you already know what you're doing... But also then something of a hassle to then get everything set up and configured the first time around. It's something I would like to do at some point, but my last go at it ended up being a time sink. It might get a partition to play around with, but it won't be primary for awhile, at least...

Also, is anyone else having headphone static? It's really annoying me. On my old computer, I had this sort of static if I had the built-in mic enabled (so I just always kept it muted). With this, though, the only way I can get the static to go away is muting the headphones, which really defeats the point...

 

My fan also sucks. At first, it seemed fine, but at low levels it would vibrate slightly.. and I thought that would bother me. I was playing with TPFanControl and confirmed it was the fan as the vibration slowed as the fan spun down/off. I'm not sure what happened, but there must have been an issue with it and it gave, because now it is very loud. Going up to the first step, it's already annoyingly audible. Speeds 1-4 are overly noisy, and speeds 5-7 sound like they should, loud and fast. I must have some problem with a bearing, or lubrication.. something. I want to have it replaced but it seems like such a hassle to upgrade to onsite just to have this done, and I'd really rather not send it in.

That's not the only noise complaint. My motherboard/CPU has a most irritating whine. I had this in my T400 but it was bearable. This thing seems to scream when the CPU is at lower power states. I'm not sure if it is indeed the CPU or the motherboard. Again, a pain and annoyance I shouldn't need to be concerned with.

Lastly, one of the most annoying issues of all I've been facing, is that the displays (both T440p IPS and external LCD via DVI-D) DO NOT WAKE UP from sleep. Not computer sleep - the displays. I come back and neither display will turn on, and the computer is not responsible. I can often hear the fan running, like it's doing something, but the indicators on the keyboard don't respond. It seems the only way to remedy this is to hard shut down, which I did far too many times before displaying the displays turning off for now. Sometimes it shuts completely down on its own...

I've read several other users of the HD 4600 graphics having this issue, in various forms, but just another Problem to add to this series of T440.

And I haven't even though about ordering the dock after reading all of those problems.

The scary thing is, you never know if you'll get something worse after having it serviced, so I'm still debating whether or not to deal with this or action fixes.

@dericbytes - appreciate you sharing your observations of the tech and his interaction with the notebook. I've only swapped HDD/RAM but may eventually need to change the fan as well. Anything to watch out for? This thing runs fairly hot, so my concern is applying the correct amount of thermal paste & contact.

Thanks again

 

@Cool I have the nvidia card, so the fan is different for this machine compared to the the one without. He did not apply any paste. The fan was just a unit that was easy to access. Just remove the back lid its 2 screws and slide off. Unflick power connector for fan. Then just remove screws from fan and pull out.

I got mine fixed onsite without paying for an upgrade on warranty. Although I bought it in uk and got stung on price so maybe I got a different warranty as standard.

Noticed my audio jack only works if I have headphones in when I start laptop. If I change sound device then it can not be regained without reboot.

 

My new fan is as silent as can be expected... some very minor mechanical sound but mostly just air. My previous fan made an annoying buzzing sound when it ran.

The tech who repaired my machine thought he had to remove the entire keyboard and palm rest to remove the display bezel and replace the panel, until I pointed out to him the relevant page in the hardware maintenance manual!

Since this is a completely new Thinkpad design I guess some cluelessness is to be expected, but Lenovo's cluelessness doesn't help. It specifically says in the HMM that a new display bezel is needed whenever the old one is removed. I even called Lenovo to ensure they shipped a new bezel with the new panel but was told the bezel wasn't necessary. And sure enough, I had to wait another day to get the bezel replaced. Even Lenovo apparently doesn't RTFM

 

Found the headphone problem. My audio Jack is slightly the wrong size. Tried a different headset today and it worked. Tried 5 different 3.5 connectors and only one fitted well enough to transmit sound

 

Just used KDE Mint in a Virtual Box. It felt really quick (i7-4900QM + 8M RAM + SSD)

 

Moved microphone from USB2 to USB3 slot and it works much better and NaturallySpeaking software runs smoother.

After the warranty tech guy replaced my keyboard the backlight does not work. Only just noticed. Also when he put the keyboard back on he knocked of one of the keys. I was not worried as I regularly removed my keys on my old thinkpad; to remove hairs that fell under them. Just noticed that he broke part of the latch. Luckily it is going to be replaced.

I think I am falling in love with this machine despite all the flaws. Can't wait until they are fixed.

 

My sentiments exactly. Even though this machine has some flaws, I'm seriously in love with it. Sure the clickpad isn't amazing, sure the LG screen has it's faults (though I'm getting mine replaced with the AUO), but the system itself is awesome.

 

I put a blank ssd in my new T440p. I installed windows all work. Next step I installed Debian with Grub.... not work. boot-loop. Never acces to the Grub and USB/CD boot !! .... if i clean SDD, USB/CD work...
Do you have a solution or tutorial for create dual boot with debi/win8 ?
Bios (v1.14)

similary problem as Lex_ (about the boot)

 

I just received my ultrabay hard drive adapter and the thing is a disgusting joke. There are metal tabs that short out the HDD circuit board unless taped over, and the thing doesn't even lock a hard drive into place. You can slide the hard drive out with zero effort even when "closed".

 

Are you using uefi for both? If you are, have you disabled secure boot? it also looks like debian may have issues with uefi...

 

Using HWInfo64 I found out my monitor name is: LP140WF1-SPK1

According to a previous post I have an LG AH-IPS display. I too have bad light bleed on startup. Although I would not have noticed it in Windows 8.1 if I had not run a light bleed test video.

It is the best screen I have had. There is a slight change in visibility when moving the screen past the 105 degree angle; its as if the screen has been dimmed fractionally but the image is still clear.

People mention the AUO is better.I have a t440p 20AN. In a previous post there was a link to a pdf with FRU numbers. It seems to be for t440p 20AW

My monitor was not there. It only had one FHD screen, the AUO B140HAN01.2.

Is it worth changing screens. Can I get the B140HAN01.2. Is that the best one to get?

Also I was trying to look for reviews on it and found it being sold for 99 dolars on amazon.com
Amazon.com: AU OPTRONICS B140HAN01.2 LAPTOP LCD SCREEN 14.0" Full-HD DIODE (SUBSTITUTE REPLACEMENT LCD SCREEN ONLY. NOT A LAPTOP ): Computers & Accessories

 

AFAIK There have been no direct comparisons between the LG and AUO monitors. The primary fault of the T440p/s displays is backlight bleed, which is almost completely attributed to how well the display was installed.

 

All UEFI was off (Legacy). I used the latest BIOS update; 1.18.

So now it's clear something is wrong with these machines, they won't boot anything anymore (no usb, no cd) even though the settings say it should.

What can we do about this? What's really causing this?

 

Here was my situation: I received my T440p about two weeks ago. I immediately noticed the deficiencies in the LG display mine was shipped with. I didn't have light bleed at all but rather a spotlight effect, fine color speckling, and overall dim display. The spotlight effect was most troubling as I could not get an even brightness across the screen at any normal viewing distance....even when viewing the display straight on. As others have pointed out, it basically took me back to early TN LCD displays...and hardly what one would expect from a $200 upgraded IPS display. Anyway, I was honest with the rep about my concerns and had my laptop shipped to a depot for replacement. And within a week I had my laptop back and it all seems fine except now my Nvidia card can't be detected to play SC2!

 

The power connecter is in an annoying spot. It crunches on my thigh when I rest it on my stomach when slouching in bed. It cruches on the floor when I type cross legged with it tilted towards the floor. I spend a lot of my time typing like this.
