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 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.
A new T440s makes multiple times problems after start or sleep mode. Windows 7 comes up but instead of login screen a black screen appears. Just the F7 wireless control gives response. When it happens after wake a programs are runing in background but the screen is black.
I did already all updates, just not my BIOS, it is 2.11 but now 2.19 is available. I hesitate BIOS updates.
I could return the laptop since it is within the 2 week return garantie.
I've just out my hdd to check whether the ssd will fit there, just checked whether the slot is ok. Then I put back the original HHD very carefully. After that I opened the extra RAM slot, took it out and put it back, also VERY carefully. I didn't harm the laptop in any way.
Then I turned the computer on and it was just a black screen, nothing happening. No indicators lighted up, except for power button. I cannot enter BIOS, no response whatsoever.
i ve got thinkpad t440s model 20AQ004VRT so it got europe only geforce GT 730M video card. I've noticed that if i use it all day long( about 4-5 hours, maybe got something to do with sleep mode) fan stops spinning and notebook gets really hot under high loads. Fan starts working only after reboot. I've tried to use tpfancontrol but smart mode stopped detecting cpu tempreture and even somehow crushed battery life detection, so ive had to remove it.
Other than that, I've got gorilla glass bit extruded from the left side. I can push it but it keeps coming back to that position.And ive had fingerprint reader error - system could not find it after some time of use, but that problem resolved itself somehow, maybe after ive removed northon protection system...
Lenovo T530. Power settings of Windows 7 and in Lenovo power Manager say that when laptop is plugged to AC adapter - NO SLEEP. But i hear how hdd stops down after some period of time and spinning again when there is a data read or write. That`s quite annoying, especially when primary storage is ssd drive. How to get rid of this "feature"?
Running on Windows 7. I've read similar problems that others have posted, which is the monitor goes black during bootup. My machine boots fine, but every few minutes the monitor goes black / dies - no backlight.
This lasts a minute or so, then the display go back to normal. Then it goes black again. Then it goes back to normal. It's not sleeping, the HDD keeps on spinning.
I've checked the graphics driver - no update available. I reinstalled it anyway. The built in lenovo utility -thinkvantage- is of no support.
At this stage I'm wondering about the integrity of the motherboard.
My T400 display works at BIOS startup but goes black was soon as Windows 7 starts to load.. Video out put works and I can see an UN Backlit image on the display. Is there some sort back light controller /driver that may be broken.
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 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.
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.
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?
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.
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.
Something strange happened on my T440s today when I first turned it on...it booted to windows, then I entered my windows login pin, and then the screen went blank/dark instead of going to the windows 8 tiles. so I closed the lid, and it went to hibernate. and when I opened the lid again the screen came back on and it worked fine.
I have recently bought a T400. At the moment, it is running on Windows XP, Service Pack 3.
After installation of Windows XP, I have installed all the relevant drivers and no yellow question marks appear in the Device Manager panel. However, during the process of installing these drivers, now whenever I plug in our take out the AC Power Plug, the screen goes blank for about a second and then comes back.
This problem was NOT there immediately after installing Windows XP and Service Pack 3, i.e. before installing the drivers. I think that it is one particular driver which may have caused this.
I have already tried re-installing the Graphic Driver.
I'm looking at a refurbished T430 online, but want the 1600x900 screen - can't find specs for that model anywhere. it's not in any of the PSREF docs at the Lenovo site. If the 2355-A17 has the 1600x900 resolution screen?
During one month usage of my T430s, I met four times of BSOD(Blue Screen) and the recent two showed the same error message: A clock interrupt was not received on a secondary processor within the allocated time interval. And the stop code: 0x000000101
Here is the screen shot:
Link to picture
When I use the software "BlueScreenView" to read the .dmp file, it says that it caused by address "ntoskrnl.exe + 7f1c0".
And recent two days, when I use Vmware workstation 8, the playing music suddenly stuck for few seconds and my screen was freezed. I thought the BSOD coming again, so I stop doing everything with my PC but then the music came back and screen was released. I think maybe the CPU is stucked again but not so serious to cause BSOD. But I treat it as a sign.
By the way, after I got my T430s, I have done lots of stability, stress test, including Prime 95, Furmark, MemTest Pro. But none of them gave me problem and my T430s all survives. But the BSOD just happened randomly.
My Config: i7-3520M with HD4000 8G RAM SSD
I enabled Intel Turbo Boost before recent two BSOD.
