I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

Hello, I am new here and I realy hope you can help me! I've have the Lenovo Thinkpad S440 (as in the description). It is the model with SSD, i5 U, Intel integrated graphics, 8GB Ram etc. The display which was build in was the HD+ matt model (1600x900 px) I've had some water in bag back pouring into the screen. I tried to fix it and after I disassembled the screen, I got all the water out of it but the backlight was not working anymore. So I ordered a new display. While I was looking for it, I came to the knwoledge, that you can take a replacement screen from the Lenovo Thinkpad T440s, at least considering that most 1600x900px displays seem to be the same for each of them. So I thought: okay, then I should be able to use the 1080p display for the t440s as well, since it also has a 30 pin eDP connector.So I ordered one and put it in my S440 and it fits perfektly. But now the display only gives a really dim short fliker while booting the machine and nothing is viewable, so the display stays completely black. Is there a possibility to fix it or can I only use the 1600x900 px displays on the s440? As I sayd the screen fits perfect and the 30 pin eDP connector also fits perfekt into the new display. If I use an external display via HDMI, the image is shown normal on this external screen. Also it seems that the new internal screen is not recognised, since in the intel graphics options I cannot chose it as the main screen, only if I go for dual screen it is an option. ... Read more

Hi,
Over the past year, since I upgraded the memory on my IBM R31 Thinkpad, I have had intermittent problems with my screen blacking out. It's not completely gone, just extremely dim, but I can make out the things on screen by using a torch. At first, I was able to trigger it back by leaving the lid open and never closing it, taking all the usbs and plugs out of the back, or re-starting it.

However, it seems like nothing I do will trigger it on now. I've done a search and apparently the commonest cause is that the inverter needs replacing. Would this seem like a sensible thing to buy?

http://cgi.ebay.co.uk/IBM-Thinkpad-...goryZ162QQrdZ1QQssPageNameZWD1VQQcmdZViewItem

The only thing I'm thinking now is, i've had this laptop for 5 years now!! I'm not sure if it's worth fixing or upgrading anymore. I mean, I love it, just cos it's lasted this long, i've upgraded the memory from 128mb to 384mb and i've bought a wireless card for it but would it be worth trying to buy and fix myself a new inverter or just buy a new laptop?

Thanks!!
 

A:IBM Thinkpad - Backlight screen black.. inverter replacement?

Well the most common things would be the inverter board you linked to, or the backlight bulb itself.

If the laptop still suits your needs, in terms of performance than its much cheaper to just fix this one, than buy another laptop of similar quality.

The great think about IBM is the great support. Here is a link to the hardware manual for the R30 model.
http://www-307.ibm.com/pc/support/site.wss/MIGR-39797.html
It should tell you how to get at the inverter and bulb.

Even if you do get a new laptop, its still worth it to fix this one up as a backup laptop. 20-30 pounds and a couple hours to fix it isn't that bad.

And i believe its called a flashlight not a torch. You could burn the house down with a torch

Hi all, 4 days ago my 2 year old S440 suddenly switched off when I removed the power cord. It still worked when I had the power cord plugged in. 2 days later the battery worked again and the laptop was running even with the power cord removed. So all good. Today all bad: the laptop wouldn't turn on again, even with the power cord plugged in. I tried the elsewhere described trick to push the power button at 30s intervals (even after removing the RAM and the HDD). But I still couldn't recover the machine. Status quo:I plug in the power chord (battery inside): the red light flashes 3 times, I press the power button and the red light turns on for 3 secs, then turns off, nothing else happensI remove the battery, plug in the chord, red light flashes 3 times, and a few secs later the fan starts and continues in a on-off-loopI plug in the connector of the battery: the fan moves a little bit for a secondAny ideas what's wrong or what I can do to fix this? Thanks!

Hello everyone,Last week's Wednesday I used my Lenovo G40-80 to do my college homework at the afternoon. It went all normally, I turned off the notebook and get to my college.At night, when I returned, I tried to turn on the notebook and was given the error when the system don't booted and both the led aside the camera and the fan turned on for almost two seconds and then turned off. After many attempts, and seeing some topics here, I tried to turn on my Lenovo using the recovery button. It worked,the system booted up normally. Problem is that the system gave video, but LCD backlight is off.I am very anxious about the possibility of being a software problem, giving the fact that the F9 key has a feature similar to the problem i'm suffering (LCD backlight on/off) and also the fact that if I connect my laptop into a TV or another screen via HDMI/Vga cables, video is showed nornally. I've done a video showing my problem and uploaded it on YouTube, here's the link:https://youtu.be/deGQw-88x68 Please, do someone has any answers to this problem?

No,  It won't work and the problem isn't the BIOS or a Lenovo limitation.  You have a 4th gen CPU  i7-4500u.  The 16GB modules only work on 5th gen or later

Dear all, I bought a Thinkpad S440 in Germany a few years ago and additionally purchased an on-site warranty extension, which is valid internationally and allows a technician to come directly to your home to fix the problem. I already used that warranty option in Germany for a broken sound card and it worked perfectly. Technician came and solved the problem on site. Now, I'm living in Japan and my S440 suddenly doesn't boot up anymore if the battery is plugged in. Works when I unplug the battery. Tried the notorious "unplug and push the power button for 30s" tip in many different variations, but nada. Probably battery dead or Mainboard problem, who knows. I'd now like to use my international warranty option here in Japan, but the Japanese customer service said they don't have the parts here. According to them, I am supposed to ask the German customer service to send the parts to them. Problem is, I cannot call them in Germany and am also tired of solving that problem myself when I actually paid big money for that warranty pack. So, does anybody know a contact address of somebody in a higher hierarchy and can help me to escalate that problem? Maybe global warranty management or something? I feel lost and am really wasting my time here.  I would greatly appreciate any help. Best,Simon

Hi, After installing Windows 8.1 I've had big problems with my brand new Thinkpad S440. The laptop has generated systematic bluescreens, mostly related to the Intel Wireless-N 7260 WiFi module. Disabling it in the Device Manager helped a little bit, but I also get other Bluescreens related to e.g.. to "usbxhci.sys" and other modules. After the BSoD the laptop always goes into a reboot-loop at the Lenovo logo during the boot-up with the only solution do do a hard shut down (keeping the power-button pressed for 5 sec).  Yesterday I tried doing a fresh install, but it did not help at all. A few minutes after installing Win 8.1 from scratch the laptop generated a bluescreen. I have updated all drivers to the latest version, and also tried to solve it by installing an earlier version of e.g. the WiFi driver. Neither one has helped.  Below is a list of the minidumps generated during BSoD's I've had during the last 12 hours since installing a fresh copy of Windows 8.1.  Please, what can I do about this situation?

Hi Kxer44, It's mainly a driver isuue as you noticed. Unfortunately I don't think much can be done about it for now.

Hello All. I have a unique problem, that I would love to see if anyone else has had or any thoughts. I am trying to deal with a Lenovo G585 Laptop. The screen broke on it, as a dog stepped on the screen, cracking it. The laptop does turn on, and I do see a picture on the existing screen, it just has a huge crack through it. So, I ordered a new screen, and replaced it in the laptop.  It is a 15.6 inch screen. Now, when I turned on the screen, I can see that the screen does take an image, but the backlight does not turn on. At first, I thought that the new screen was defective, but I have since replaced it with another screen, and it does the same thing. I have also tried to turn the backlight on through the keyboard, with no luck. Here is the weird thing. If I put the old screen back on, it lights up no problem. Then when I put the new screen in, right after and keep the laptop plugged into the wall. the new screen also lights up. When I take out the power, the new screen no longer lights up, but the old one does. I don't think its the lcd cable as that doesn't explain the power/no power thing, and this laptop has done this now with two different screens. What am I missing?

Hi fellow lenovians. Inspired by numerous posts on the Internet on how to replace the LCD on T520 I decided to do a similar surgery on my machine. My Lenovo T520 came with a 1366x768 screen, a LP156WH4 (TL)(BL1) which uses LED as backlight and I wanted 1920x1080 instead. I searched ebay for "B156HW01 V.4" and ended up ordering this one. In hindsight I should have paid more attention to the word compatible in the item description because the monitor I received was a Chimei N156HGE-L21. I'm wondering how the seller defines "B156HW01 V.4 compatible". Funnily, according to the ebay link it uses CCFL  as backlight while the Chimei seems to be using LED as backlight ? which is fine since the original LCD uses LED too. Disassembling the old LCD and mounting the new one was very easy. However, upon switching laptop on I get exactly the same experience as this guy: The laptop turns on, there is backlight, the harddisk is running but the screen is blank. I can use the Fn + brightness up / down buttons to increase the lightning, but even with a strong flashlight I don't see a faint of the Windows splash screen on the LCD. If I put the old LCD back then everything's fine - except it's not the new one...  Now, before returning the LCD I'm wondering if there's anything I should try? There's backlight so I don't think it's the inverter. I can almost only imagine the LCD being faulty?

A:Lenovo T520 replacement LCD - there's backlight but blank screen

There is no inverter with LED backlight.  As inverter converts direct current to the AC needed by a CCFL. You have no inverter so the fact that your backlight comes on means the new screen has an LED backlight.  A CCFL scxreen would have a separate backlight connector, typically a 2-wire plug with one pink and one white wire.  Make sure the cable is making a good connection, otherwise, I would assume the new screen is bad.

Hello Lenovo Community!  I purchased a Lenovo Flex 2 14" Laptop last Saturday (6th of September 2014) and I noticed when using it at night time that there was a yellow tint coming from all corners. This yellow tint isn't really noticeable when on standard applications with a bright colour but when watching films or viewing dark images it is really noticeable. I returned the laptop to the store (PC World) and they happily provided me with a replacement, however the same problem is happening with the replacement which I got today. I have included a picture below which shows the tint when streaming a film on Netflix, as you can see it is really noticeable and not something I have seen with any other Laptops I have purchased. The same yellow tint appears on dark images or applications, not just on Netflix.  Has anyone else expierenced a problem like this before? Is this expected? Or have I just been extremely unlucky with the two laptops I have been given? Thanks for any support/advice, Shane

Hello,  I recently had a problem with my Thinkpad S440 that I purchased 1,5 year ago. At some point it was not able to boot up for no apparent reason. As the warranty was no longer valid I had it expertised. The expertise showed that the screws on the hard drive were loose and one of them started to move inside of the laptop, causing a short circuit on the motherboard.Anyone ever had that problem ? Any idea on what I should do ?It seems to me that it is a huge problem of fabrication which I would not be able to avoid by myself... Sorry for my bad english and thank you for your answers.Cheers.

I posted a similar question earlier and people referred me to the Yoga (much appreciated).  However, I was interested in the 2.6 lb carbon version with touch screen capabilities.  Asus has a Spin 7 model that is very good at 2.65lb, but I miss the red mouse toggle in the middle of the keyboard and Asus's track pad was designed too large....causing unintended tapping.  The Yoga, while nice, is heavier than I was looking for.  The 14 inch screen is about 3.3lb? the 12 inch at 3? I thought that some of the earlier Thinkpad Carbons had touch screen and was hoping they would make a return soon.  Thanks,

https://support.lenovo.com/ec/en/products/laptops-and-netbooks/thinkpad-s-series-laptops/thinkpad-s4...
 
That links to this PDF with the part numbers:
https://download.lenovo.com/parts/ThinkPad/s440_fru_bom_20130717.pdf
 
Would it be this one "04X0984 C Cover w/KBD UKE LTN <PRIMARY>"  ?
 
Please validate the part number with your retailer.
 
Regards

Hi forum, i own a Lenovo S440 and the power button have shattered, the PC is almost 3 years old and therefore is no longer covered by warranty. I've tried to search for a new power button, so that i might replace it myself but i can't seem to find anything.  Do anyone know how to acquire a new power button for this model?.

Hi,i have Lenovo ThinkPad T470 (LENOVO 20HD0002MC) and recently has started a strange problem:While booting at first Lenovo logo shows up (where you can get to BIOS by Enter key) and right after screen goes black. When i power down laptop and boot again (sometime few times) intead of the black screen there is a prompt for Bios password, like it should have and booting continues to OS.Enter key for BIOS doesnt work while it slill get stuck on black screen just right before it loads the BIOS (after trying few times with power -off/on it gets to BIOS and i can boot normally)I have BIOS firmware updated to the latest version, so as well drivers for hardware.Im not aware of any change that could potentionally start this issue, maybe after updating bios to some newer version.Otherwise im using Windows 10 with latest updates, but i dont think this could cause the issue as its way before windows loading.Thanks for the help.

My sister dropped her T410 and cracked the LCD screen, which clearly was not covered under the basic warranty.  The $950 quote for repair was a little steep (basically the cost of the laptop) so we decided to try a repair ourselves.  I replaced the LCD screen with a model suggested by the Lenovo rep.  With the new screen in place, the backlight doesn't function at all (can see information on the screen with a flashlight but otherwise nothing).  I also put the old screen back in (which previously was backlit despite being cracked) and observed the same problem.  I made sure the LCD cable was seated firmly at both ends. Considering things as they stand now, my question is about the best route to take from here.  As I understand it, since the LED backlight is powered by the system board, we either buy a new system board or use this laptop as a "desktop" attached to a standalone monitor.  Replacing the LED sub card seems questionable for this particular problem (saw another post here with that conclusion).  We could replace the LCD cable, but it seems to me more likely that the fuse on the motherboard is blown.  If it comes down to motherboard vs. desktop use, we'll probably avoid the motherboard replacement since it is somewhat expensive. Am I missing any obvious ideas?  Should I consider replacing the LCD cable more seriously?  Is the LED sub card more relevant to the LCD/backlight than I think?  I'm hoping t...

A:T410 LED-backlight LCD screen: suggestions for no backlight

spencerkellis wrote:Is the LED sub card more relevant to the LCD/backlight than I think?Yes, the backlight is LED. What else would that card be for? You should also make sure that the cable to that card is seated all the way, from what you describe it sounds like it came loose. http://www-307.ibm.com/pc/support/site.wss/MIGR-72786.html

Hello, Since two weeks my Lenovo Thinkpad screen flickers on the right side and on boot up or recover from stand by. This becomes pretty annoying and I have updated all the drivers and also upgrading to Windows 10 didn't work neither. The warranty was due June this year, so I don't know that if I have to repair it that it will cost money. But I think it's strange for a screen to be broken in one year and 3 months. If you perhaps know a solution for this or know how it will be handled by Lenovo if I send it away for repairs please tell me. Yours faithfully, Joost Kolkhuis Tanke
