I updated the BIOS to 2.26 a while ago and ever since then there's no on-screen indication of caps lock on/off, screen brightness or volume when I change it. Since it seemed to be affected by BIOS, I updated again to 2.27 just now, but the problem persists. I needed to update the Hotkeys Feature Integration by downloading the utility thingy from this page. Probably wasn't a BIOS thing after all.
I have a 3-yr old Thinkpad T500 laptop w/ XP. My on-screen volume and brightness displays have recently disappeared. Spoke with customer support and was advised to download all the machine updates....did that, but still not working.
I can't adjust my screen brightness using the Power Manager. Updating to the latest release of the ThinkVantage Communications Utility did not solve the issue. I can't make the screen either brighter or dimmer.
My T440p slightly adjusts the screen brightness depending on what is being displayed. For example, on Chrome, one page might have more images, so the screen slightly adjusts brighter or darker. Another page it might slightly adjust again. And it does it when scrolling down a page as well. It is distracting, and I want to disable it? I'm on windows 7.
The company I work for just gave me a new Thinkpad T440P and I have a screen Brightness problem. the shortcuts on the keyboard doesn't work with or without the fn button and the brightness gauge doesn't show up in the power options too.
Someone suggested to that I should download and install the latest Intel HD Graphics Driver for Windows 7 from the support page [URL] ... but after the installation ended a pop up on my screen said that my Laptop doesn't have the minimum requirements for this driver! so who come it's in the drivers section for this model?
Does the Microsoft Window's 7 installation CD automatically recognize the mSATA and the Optimus in conjunction with the Intel HD 4000 as well as the fingerprint reader for login? Or do I have to download the drivers and install ExpressCache separately off of Lenovo's website... trying to stay clear of Lenovo drivers that might conflict with Intel's and NVIDIA's.

Since receiving this laptop, OSD birightness control has always failed to work, i.e. does not appear on the screen when using the Fn+F5/F6 key combination nor does it control actual screen brightness AFTER FIRST resuming from sleep mode.
Sequence of steps that demonstrates the above symptom: 1. OSD brightness works fine after reboot 2. Putting the machine to sleep (I do not use hibernate) for a duration longer than a few minutes 3. Open lid the first time, hit Fn to resume machine 4. Pressing Fn+F5/F6 key combo does not display the brightness slider nor does it control brightness 5. Closing the lid and opening it again, causes OSD brightness slider to flash briefly and is now fully functional using Fn+F5/F6 keys
Your tech department should easily be able to re-create this issue on any stock T440S/Win7pro machine, as I have seen others comment about this very issue across other T440/OS variants.
So, I just got my shiny new T540p with a 3K display and Win Pro 8 installed. I promptly upgraded to Win 8.1 Pro and now I have a problem with the Intel HD Graphics. Basically, the system will not turn the display on after a sleep and I can't adjust brightness.
I tried downloading the drivers from the support page, but they reference a Intel(R) HD Graphics 5000 card, whereas my system says it has a Intel(R) HD Graphics 4600 installed. When I try to run the driver install anyway, I get a message saying that my system does not meet the minimum requirement for installation (?).
I tried manually installing the Intel(R) HD Graphics Family driver instead. This fixed sleep and brightness control, but then all things 3D was completely messed up (like buttons in Skype and Chrome).
yesterday i open my laptop(model 6530s) and clean motherboard but after setup when i start laptop that time on top right corner showing one message MOUSE NOT DELETED and mouse pad not working any more ..Now what can i doi tryed to open motherboard battery but still same ...
another problem when i watched movie some of website laptop suddenly going off ..also when i try to do somthing on bios that time also going trun off
Inspiron 17R N7110 has no power, I was watching movie and the laptop just froze, after waiting a few minutes I performed a hard power reset, machine was restarting, abruptly shut off and has been dead since.
Tried the power reset by removing the battery and holding the power button for the static discharge ... and so on. No luck. Machine has no lights on front, it is completely dead, battery was 100% charged. Tried two charger cables, both have green lights till I plug them into the machine then green lamps die.
I think it would be the DC power connector or the motherboard... or something else that I have not thought of yet.
I rarely use this machine but a couple of months ago I went to boot it up and found that I was not able to get past the Windows splash screen. Sometimes I don't even get the Windows splash screen, I just get a black screen. Rarely I get a Windows screen saying that it is diagnosing a system problem or something to that effect and I can even get to where it will allow me to do some Windows diagnostics but nothing ever comes of it and the process is extremely slow.
I called Lenovo, but of course my machine is out of waranty so the tech just gave me a few pointers and said I could send it in to the depo but the potential repair cost could range up to about 75% of what I paid for the machine in the first place. Anyways, after having me try a few things in the BIOS he suggested that it was likely the hard drive. I mistakenly thought from the time that I bought this machine that the OS was installed on the 24 GB SSD so I ordered a new SSD and swapped it in. This made no difference at all as I have now learned that the mSATA SSD drive is merely for cache to speed up booting.
I am afraid that this means the main HDD is at fault, and quite frankly, if I replace it I am going to do a fresh install of Windows 7. But I do have pictures and docs that I would like to salvage if possible.
I have a problem with two T400 thinkpads. The first T400 was dead when I bought it ( suspected graphics card ) . Well I managed to get this laptop to boot up. The screen was black but I found by chance that if shine a lamp or light on the screen it is working. Now being able to see what I was dooing on the screen faintly. So I updated the bios & that did not fix the problem but I was well happy about finding out this trick. I then added 8Gb kingston ram which works with my other T400 laptops. I installed Win 7 ultimate. The laptop is working fine. No issues just extreamley dark screen almost black "but working" Very strange indeed.
T400 - TWO
Now the second laptop was working fine. But I was swapping the parts with the non working laptop to determine the problem. Now I have two T400 laptops with a dark almost black screen. But over about a month working on them I am making progress. I am determind not to give up on these computers. This is not like fixing or repairing a computer. More like rezerecting a computer. I did not intend to spend so much time on these laptops but I have found a common problem that effects a lot of people. I would love to know why a working laptop when re- assembled gives an almost black screen & still works. Normally I would just buy a new motherboard & bin the defekt one. What I need is some command codes to try to make the screen brighter. Is this planned obsiletion or just a graphic defekt myth. Because after throwing away more supposidly dead motherboards with a graphic defekt than I can count. I am starting to think that if I get the brightness back on my computers I will have sloved a major black screen problem. It is not the graphic processor. I have been playing fifa 14 with a lamp shining on the screen. It played fine, not jumpy ,no colour stripes just very dark.
Today I was surfing the internet on my Lenovo t500 ubuntu. After a Kernel Panic ( i'm not sure it was that some text on my screen ). I shutdown the computer and restart it but the screen stayed black. Not even Thinkpad logo at boot. The fan is working the lid are working, the keyboard too. So after trying to fix it i went on a walk while the computer was on and when I got back I heard the ubuntu noise when it start. So i try but terminal to run music and it works but the screen stay black. I tried to remove RAM, 10 times shutdown without battery or plug. Nothings worked. I cannot try without another screen yet..
Lenovo T400 to install Windows XP on it..It previously worked fine with windows 7 and 8.1.so it boots in windows XP preinstall screen, it formats hdd and like usual installation automatically restarts after that BUT its black screen, lights and sounds show that it works and goes to next screen BUT the screen is still black. Powering down and turn on again is not showing any screen picture. Opened it removed Bios battery, turned up after few on and off it starts it reset bios.
So now there is picture and it goes on the next screen of windows instalation like normal, after installing devices and stuff it automatically restarts like usual BUT it has NO screen again, black screen, lights and sounds again show that its loading windows end instalation screen but no picture on the screen. Reset BIOS again, it starts normaly and this time it shows BSoD with code 0x7B, after BSOD Black screen again..Maybe its a BIOS setting?!? tried installing with drivers for AHCI and tried installing without drivers for Compatible , what else can it be? Updated the bios to latest version, same result. To say it again - it works fine with other windows, but XP must be installed
I've purchased this ram from the lenovo site for my T440p laptop and they said its compatible with the original 4gb RAM which it has. but when I install it in the other free slot and turn it on it cames with a black screen and stucks in it!! When I take it out everything is ok and it turns on normally.
I just recently received my first lenovo laptop, the T440s. The overall built quality is excellent and performance is great. However, I realized there is a dead pixel on the screen. I am stilI within the 21 days return limit. I am wondering if I am able to get an exchange for one without such defect and not subject to the restocking fee?l
My T540p with Window 7 is experiencing problems starting and shutting down. After booting up I often get a blank screen where just the moused pointer is displayed. I have to hold the power button down to shut down and then try again. Sometimes it takes 2 or 3 goes to boot-up. Quite often when I shut down Win 7 The desktop icons disappear but the desktop background continues to be displayed and the notebook doesn't shut down.
I have a T420s that I bought a couple weeks earlier, it's a used one, so there's no warranty with it, I used it several days without any issue, I don't use it very frequently as I use my corporate one most of the time.
Someday when I wanted to turn it on, it stacks on a black screen and it beeps one beep then two other, nothing showing on the screen not even the thinkpad logo at startup, I thought it was a RAM related issue so I put the one from my corporate PC but without any luck, so I wanted to see if its graphic controller issue, I plug the VGA cable on the laptop and my TV and here I can see the thinkpad startup logo but after that I see a message on the screen telling :
"Real Time Clock Error - Check Date and Time settings. Press Esc to continue or F1 to enter setup" and when I press either one nothing happen at all, still stacks there.
This computer originally had an issue with the 2100 Detection Error. This computer was previously built with no issues when it was imaged with our company's Windows 8 configuration in which I am highly sure our IT engineers have worked closely with Lenovo on. Also out of the tens of thousand computers that were imaged this way this is the only system I have dealt with that has this issue. I luckily had a good T440 I could test this system's SSD in. The hard drive appears to be fine with no issues. So that rules out to be the SSD. I ordered a system board under warranty and installed it. Everything so far responded fine with the system board replacement until I performed the model type/serial number and UUID update using my 1.86 maintenance update USB thumb drive. After that completed the computer froze on the Thinkpad Logo screen. I verified again for my piece of mind that the memory module and SSD was fine. Sure enough those components were tested fine in a known working T440. So I submitted the system board as a DOA with an explanation. I received another system board to replace with the DOA. I installed that system board to once again update the Model Type/Serial Number and UUID using my USB maintenance disk 1.86 thumbdrive to once again end up with a locked computer at the Thinkpad Logo screen. I have replaced a couple of other T440 and T540 system boards during this time also with using the same USB maintenance disk thumbdrive used for updating those system's model type/serial number and UUID. So I know the issue is not with the USB thumb drive. I am very frustrated with this system. I hate to keep submitting DOAs for the same system.
Since the BIOS is part of the system board and I have not had these issues with the many T440 system boards I have replaced successfully that performing a BIOS update is not a good excuse why this doesn't work on this particular T440 and since after replacing a system board under "DOA" and updating with the maintenance disk and froze there is not a way I can run a BIOs update on this system now right?
Had the laptop for 11 months no issues, I woke up to find the computer stuck on the startup screen. Tried rebooting, took out the battery, tried it pluged in, unpluged and it keeps stopping at the startup screen.
