L440 LCD backlight issue

Q: L440 LCD backlight issue

Hi everyone! I have a ThinkPad L440. Just out of the box the lcd was very very dark (can see image with a flashlight) no backlight was on. I got a genuine replacement lcd, replaced and still same issue, no change. After that I have upgraded the BIOS to newest - didint help. This is not a driver issue as problem is presistant from start of the pc. External monitor works fine. Any ideas?

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

A: L440 LCD backlight issue

Hi Shlapenka,

Welcome to Lenovo Community!

We are sorry to hear that LCD backlight is not working in L440 laptop.

Usually, these symptoms indicate a blown fuse on the motherboard. The issue comes up frequently when LED-backlight screens are broken. Lenovo does not do this type of repair (other than motherboard replacement).It can be done, but most places do not have the specialized equipment to diagnose and repair.

I would like to suggest you to visit the authorised Lenovo service centre for the hardware assistance.

Hope this helps. Do post back if issue persists!

Best Regards,

Poojitha.

I made a schoolboy error leaving the battery in while upgrading the screen on my L440... voila i have blown the backlight fuse on the motherboard. I have had this issue before with a T430, it was easy to fix by bridging the F7 fuse on the motherboard.... (I used a small pin head size drop of metalic glue) however i am not sure which fuse to look for on the L440? Does anyone know the fuse number or location.... ? It is the backlight fuse that has gone on this board as the actual screen works on another L440 i have here. If no one can help then i will let you all know when I have fixed it, there does not seem to be anyone else out there that has had this issue with the L440 lol ;-)

Hello Everyone,

I have an odd problem with my Toshiba laptop. The Laptop starts, fans turn on hard drive is running but there is no screen and no HDD light blinking. I first though it was a backlight issue but when I shine a bright flashlight on the screen I see nothing. I also plugged in an external monitor and had no results. The only light that lights up is the power on indicator. The LED for the HDD doesn't turn on. the caps lock key doesnt turn on when pressed but the FN indicator turns on when FN is pressed. I get no POST beeps or anything else. I tried to boot up the machine with no RAM and no HDD with the same results. I took the laptop apart and found no water damage or any damage of any kind. Any one have any ideas before I call it quits?

Thanks

A:Possible Backlight Issue?

I get no POST beeps or anything else. I tried to boot up the machine with no RAM and no HDD with the same results.I'd suggest downloading the instructions for your model from the mytoshiba support website, and using the specified procedure (varies between models) to clear the CMOS data in case it has become corrupted and is causing the BIOS to set an unbootable condition for the CPU. Beyond that, unless anyone else has another idea, service might be the only option.

Hi!
I am experiencing issues with keyboard backlight on my laptop Vostro 5468 running Ubuntu 17.04. On battery it works normally (waits 1 minute to turn it off). On AC keyboard backlight turns off automatically after 1 second or less if I didn't touch the touchpad or keyboard. The same issue was on Ubuntu 16.04 and 16.10.

Greetings everyone! I have recently upgraded my Windows 10 OS to the anniversary update recently and shortly after the update, my laptop's LCD backlight randomly went off and wouldn't go on. At first I thought it could be the drivers update that messed up the backlight but I knew it doesn't work that way. Here are the list of things I've tried: - Rebooting (obviously)- Reinstalled the Intel HD graphics card with the latest version from Lenovo's support- Reinstalled the Nvidia graphics card with the latest version from Lenovo's support- Also tried previous Intel & Nvidia graphics card driver versions- Keyboard's built-in backlight controller doesn't do anything I'm starting to think it's hardware related issue and if that's the case, where's the trusted website to obtain a LCD screen replacement to fix it myself (I've already found tutorials on how to replace it, because warranty expired literally last week...) Thanks!!!

I have a T440p which came with a non backlit keyboard, which I wanted to replace it with a backlit one. After installing the new keyboard the backlight wouldn't come on (i'm using Fn + spacebar, the keyboard has the light icon on the spacebar and the OS shows an icon for the backlight).I tried swapping it out with a friend's keyboard (from a t450s which was replaced due to a damaged key) but without any luck. Could this be an issue with the motherboard or controller? What are my options?Thanks! I appologise if I have overlooked a topic describing this issue, but all of the topics related to the keyboard backlight were related to the fact that the keyboard wasn't backlit while the user was expecting it to be.

Hi!
I have a 7450 which suffered some liquid damage. The good thing is it still works and when plugged into an external monitor everything is hunky dory.
However, without an external screen the picture is barely visible. I thought the backlight had blown so I changed the screen however the replacement screen had the same issue?
I've read it is something to do with a fuse on the motherboard, is this correct? The replacement screen had the electronics bar (invertor?) as part of the screen but I did not change anything else.
Any help/advise would be much appreciated!
Thanks

Please provide us the LCD part# you replaced? 
If the issue is still the same with new LCD, probably the LCD connector on the motherboard is gone. In which case we have to replace the motherboard.

So I recently upgraded my late 2015 imac's processor from an i5 to an i7, and when i put it all back together, the screen would not turn on. Well technically it turns on but the backlight does not work. (I can see everything if i shine a strong light on the screen) I've reopened it a few times to try and see what the problem is, but I cannot find anything. The connections are good, the cables are good, nothing appears to be broken or out of the ordinary. Does anyone have a clue on what is messed up and what I would need to fix/replace? I don't want to go to the apple guys....

I believe there are 4 possibilities for the issue:
The power supply, the 2 display connections on the logic board, a fuse somewhere, or the GPU.

specs:
iMac (Retina 5K, 27-inch, Late 2015)
4 GHz Intel Core i7 6700k
16 GB 1600 MHz DDR3
AMD Radeon R9 M390 2048 MB
Crucial mx300 750gb 2.5'' SSD
 

A:iMac 5k backlight dead issue

So i just looked at the diagnostic leds on the logic board and when i turn it on, the first 3 light up and the 4th doesnt. i read that indicates communication between the board and the display. so i think the backlight board is the issue. any thoughts on this?

Now, I suspect that the inverters are fine and I'm wondering about the LCD switch or LCD cable. I suppose I could just buy a cable, but before that, I wanted to take a step back and try to figure out if I'm overlooking anything. I've not been able to find a picture or location of the t400 lcd switch in either the lenovo hardware manual for the t400 or elsewhere online.Hi,I've got a thinkpad t400 with CCFL backlight. I recently replaced a bad LCD (the backlight was working at the time) with a new one. However, while the new screen works, it's backlight did not. I ordered a new inverter and plugged that in - still didn't work. I grabbed the old screen's backlight and tried it with both inverters - did not come on. I then grabbed another laptop I have and plugged in the old screen's backlight - it came on. Plugged in the new screen's backlight (while lcd was still plugged into the thinkpad), it's backlight came on.So, I know both backlights are fine, and suspected I just had a crappy inverter. I got a replacement new inverter and it still doesn't work. Tried new lcd and old backlight with all three again, no dice. Backlights still turn on when connected to spare laptop.

I recently got this amazing 1080p monitor for my custom rig and I love it! Well... most of it.
There is this problem with the backlight, where when the monitor turns on after a while of inactivity, the backlight turns on for a split second, then suddenly goes very dim. The brightness setting is unchanged; kept at a solid 70, yet it's a quarter as bright as it should be. I can go into the menu and change the brightness, and I can tell, faintly, that it does adjust, but never up to the proper level.

To remedy the issue, I repeatedly turn the monitor off and on until the display finally lights up properly, and it stays that way for the entire time I am using it. At the start of the session in which I write this post, I had to do this at least 20 times before it worked, so I finally decided to really look into this problem.

It seems this is a unique issue, as I found absolutely no matching posts on the interwebs by searching with the all-mighty Google Search. Is there anyone that can provide some insight as to why this occurs, and/or how to fix it?

Thanks for your time.
 

A:Issue with an ASUS VK-248h Monitor Backlight

New theory: Bad capacitors... somewhere. Possibly power supply

After a day at work, observing some coworkers working on used LCD TVs (and working on one myself), I now understand quite a bit more about such things.

I had removed the display from my setup and left it on the floor for a few days. Today, I decided to try it again. The backlight started up perfectly fine, surprisingly. The ASUS screen showed for a couple seconds, then went off, as normal. Then, when it's supposed to activate the selected display input, it shows the screen for just long enough to get half a frame drawn, then goes completely black. Turning monitor off and on repeatedly, and trying different input methods, gave same result. I got it to work once, but at that time the backlight had gone too dim again.

I think now I might know how to fix it, but I can't for the life of me figure out how to take the dang thing apart! Lol.

I had this same problem going from Win7 to Win8 and now again to Win10 Pro. It did not occur when I upgraded from 8.1 to 10 InsiderPreview. No matter, just go to the Samsung support site and reinstall the Windows 7/8 drivers and Easy Settings Setup (Samsung proprietary software) http://www.samsung.com/us/support/ow...NP900X4C-A01US.

Even after the updates and software installs it will crap out at random. Run the Settings program and the keyboard backlight magically comes back to life.

Hi everyone,
I have an Inspiron 15-5559 laptop and I've been trying to turn OFF the backlight on the keyboard but none of the methods were successful.
Here are all the things that I tried:
1. Pressing Fn+10, as well as just F10 while the Fn key is locked. Keyboard backlight stays on. 
2. Installed Quickset, same as above.
3. Installed DFEP 2.2 Utility (after uninstalling Quickset), same as above again. 
4. Changing the settings in BIOS in the Keyboard Illumination section.
All of the above will allow me to change the settings on the software side, whether it's selecting OFF/50%/100% brightness, or ON/OFF, or on-screen slider. None of them actually changes the keyboard backlight brightness.
Please give me a hand on how to turn off the keyboard backlight. Thanks.

I have a Dell Inspiron 17RSE laptop (the SE = special edition of the 17R (7720)). Lightning stroke the router which was connected to my laptop through an Ethernet cable. The laptop was off during the strike, but afterwards the router was fried and the laptop screen did not power on (or so I thought) when the laptop was powered on. I then connected an external monitor to the VGA out, and this works. The graphics card also seems to be picked up correctly inside speccy/HWMonitor/Everest and CUDA acceleration works inside Adobe Premiere Pro, so I guess I can rule out a fried GPU. The monitor Part Number is N173HGE L-11 rev.2 (ChiMei) --- and in Everest it says Manufacturer: HDKPVƒ173HGE --- http://www.laptopscreen.com/English/screen-part-number/N173HGE-L11/. As I said initially I thought the screen was completely blank, but upon shining a light on the screen I can see an image on the screen, just very faint (btw the display brightness is set to max). I then looked for the LCD power inverter, but realised the screen is a LED screen so there is no inverter. So I'm thinking it could be a burned out fuse near the LCD connector cable on the motherboard itself, or the LED backlight is burned out.
What do you think?
Other changes in my laptop state since the lightning strike:

1) the laptop seems to overheat when running Adobe Premiere Pro -- which is set to use GPU acceleration. Using HWMonitor it seems to be the CPU, not the GPU, that overheats and all 8 threads of the CPU... Read more

Dell 5558 comes with an optional keyboard. Apparently, the bios is tweaked for machines that come with a backlit keyboard while your machine doesn't. The only option is to purchase and replace a new backlit keyboard from EBAY or AmaZon and install it. That will work, do check out instructions before replacing keyboards.

I had a customer dropp off an Inspiron 1525 laptop due to the "not charging issue". Therefore, the dc jack power board was replaced. However, when the laptop was put back together and turned on, we noticed that the LCD was extremely dark as though the backlight was shot.
When we hooked up the 1525 to an external monitor, it worked great. We thought it was the inverter so we replaced it and still "no backlight"! We changed the lcd cable and still "no backlight". I even swapped out the LCD screen and still "no backlight". I tried the original LCD screen on an inspiron E1505 and it worked great. What the heck is going on? I even tried connecting the LCD screen to another 1525 motherboard that we had around collecting dust and still no backlight. I'm extremely upset at this point. This problem seems to defy all logic to me. Obviously the LCD Screen and inverter are fully working.. Any thoughts? Is there somekind of weird issue that only dell knows how to fix. I'm thinking of getting another 1525 motherboard but fearful it will not fix the problem. What am I missing?

New to the forum so Hello everyone.

I understand how to turn down the level of brightness through backlight control but how do I decrease the level even further? The slider in the brightness bar is all the way down (left) yet at nights the light from backlights are too bright!

Couldn't someone please help me out?

Dimming is an option but it still doesn't decrease backlight.

A:Backlight - Decreasing backlight Level more

let's see: there should be backlight and brightness adjustments on the monitor, plus contrast which does affect final light output somehow, plus all those except backlight should be duplicated inside video drivers on your computer and gamma on top of that. If it's a laptop then there should be some combination of Function key and arrows to adjust backlight directly. If you can't get the screen dark enough with all those controls, could be something wrong. If controls are too limited and your environment is totally dark then buy anti glare screen protector, that usually cuts the light coming out probably at least by half.

Hi, There seems to be some problem detected for my original 16GB M.2 SSD, so I want to replace it with a new one. I bought the following one, which should be compatible https://www.amazon.com/dp/B00KBZH72I/ref=twister_B00KBZH7E6?_encoding=UTF8&psc=1 My question is, after I get it, should I just remove the original one and install the new one? Is there any other thing I should to complete the replacement? The OS is on my HDD, but I don't plan to move it to the new SSD. In this case, do I just need to remove the old one and install the new one? The reason why I ask is that the manual says: "Ensure that you partition the M.2 solid-state drive after installing it on the computer you are servicing. Otherwise, the M.2 solid-state drive will not function correctly." Thanks a lot!

Hello finally I got my L440 and made RAM upgrade to 16GB and I also want it to have an SSD. After reading all the manuals and forum messages I think that it have  a sutiable port for an mSATA SDD which will solve my problem in a great way without replacing anything.
 
My question is, my machine didn't come with an mSATA or WWAN option. While making the RAM upgrade I checked the ports and there is only one seems to be suitable for mSATA but since area is too small I couldn't be sure if it is the one. Can you please check the attachment and tell me if any mSATA will fit in that port? Or maybe it is not for mSATA and I should go with the traditional SSD solutions by replacing the disc?
 
Thanks

A:msata SSD for L440?

Hi,
 
According to the Hardware Maintenance Manual, page 70 that slot is for a WWAN card or M.2 SSD.  An mSATA SSD will not fit.
 
From what I read here in the boards, finding a high capacity SSD in the right physical size is  a problem.  There are multiple sizes - IIRC the 42mm version is used in Lenovo laptops.

About 2 mo ago I got a brand new (warehouse fugitive) L440.  It had Win7 Pro 64bit.  the first thing I did after starting it was to let it upgrade to Win 10.  I'm a big fan and really like it, the 440, not so much.  I like the speed and quality of the build, It does everything I want and does it exceptionally well, I just can't stand the keyboard.  After reinstalling Win 10 in my T400 everything is finally working as it should and It has a far superior keyboard.  I want to reset it to give to my brother.  When I go to reset it I only get two options, and I don't really want to lose all the factory installed apps.  I'm alson a little concerned that Windows Explorer is showing Windows 7_OS (C.  It has all the app files.  It's not shown as a reset option in Settings, tho.   What's the best way to go here.  I still hae just shy of 4 year s of warrantee on it and don't want to mess that up.

I have an L440 (20AS) that has an M.2 expansion slot. My laptop is having the stock 500GB HDD as the only storage installed as of now. I am thinking of installing an M.2 SSD and using that as the primary boot disk, while keeping my current HDD as it is for pure storage purpose. I have a few questions:1. Is it possible to have such configuration without any hiccups?2. If yes, which would be the best M.2 disk to buy? Any suggestions?3. Is there any way to transfer my current system from existing HDD without reinstalling Windows (I am on Windows 10) on the M.2 SSD? My current C: drive is 65GB (25GB free). All data except installed softwares are in D: drive which is 400GB. So if everything is OK, I will try to buy an M.2 SSD around 128GB and will have to transfer my current C: to that, if that's possible.

A:L440 - M2 Sata

Short answer is yes. My L440 has a Transcend TS256GMTS400 I installed in the M.2 slot, and the software that is downloadable for it allows you to copy the O/S drive to the SSD and boot from it. My L440 goes from power on to logon in literally a few seconds and I still have the 512GB HDD available for things that don't need the blinding speed of the SSD.

So I got 2x8gb of RAM, my L440 came with 4. I took out the 4gb slot and put the first 8gb stick on there. My problem is that I can't put on the second RAM stick. The RAM pins dont slide in like the first one. I try to lightly push it in but It doesnt slide in the slot. Am I doing something wrong? Where exactly are the pins supposed to go?  

A:L440/L540 second ram slot

Hello Mui, welcome to the community,
 
there are two slots, one on top of the other, on the L440.  When inserting RAM you need to ensure that you initially position and insert the module at an angle of about 20° to the slot and then push it down into place.  See p74 (pdf p80) of the Harware Maintenance Manual.
 
If needs require I'm sure you will loads of video tutorials on YouTube.  And please don't forget to let us know how you got on.

Would anyone from Lenovo be able to give me the 'supplier part number' for an 8GB DRAM or DDR DIMM that works with this L440 Laptop - Type 20ASS06Y00 S/N R9****** ?

A:L440/L540 ram compatibility

03X6657 is the Lenovo part number.  That corresponds to several manufacturers' part numbers off various brands.
 
If you are buying non-Lenovo-branded RAM, you need DDR3L (1.35v) 1600 mHz SODIMM.  It might be described as PC3-12800.  Avoid RAM labeled Value Ram.  I always suggest checking return policy on RAM before buying.  Everybody has their favorite brands.  If I am buying RAM for myself, I like Corsair Vengeance.  I have never had a failure or a compatibility problem.

A:thinkpad l440 cpu upgrade?

If you do it yourself it will certainly be cheaper, but the CPU is not considered customer-replaceable, so it may affect your warranty status. If you can do the replacement in a professional manner, so it doesn't look worked on, probably nobody will complain, as long as you keep the old part and replace it back before getting service. The FRU of the i7-4600m is 04X4049. You do not want to get one marked "ES" (engineering sample). The ES parts may not be final versions
