Thinkpad T400 Screen broken

Basically, I set my laptop down on my books too hard, and the LCD cracked(Not horribly, but I want it replaced).
After a while of searching with lenovo's system, this is what I found:
http://gyazo.com/b8b094e346dd7263d26c5986d48ea8b5.png
So I assume I need an LCD with Manufacturer's P/N of 42T0495? Does it have to have that part number, or is it fine to find any other PANEL LGD 14.1" WXGA from a thinkpad, or do I have to have a LCD with the FRU number that is the same as it says on the page?
Where would you recommend me buy the LCD?
Any help would be appreciated.
thanks

Will this screen work?

According to your posts, I think it does. But I just want to confirm.
Also, from the photos on eBay, the some LCDs for the screen seem to have different cables on the LCD.
When I opened up my laptop, I took a look at the back of the LCD, there was no cable runnning down from it.
T400 screen with no cable running from it:

Or maybe I'm just being really stupid, cause I unplugged a cable when I removed the LCD. Is that what it is?

Thinkpad T400 screen

Does the T400 have a matte screen? Or have they switched to the glossy screens?
Thanks.

What is the default option? I don't see a choice anywhere in the ordering process.

T400 Screen Broken/Blackout, or maybe the video card?

Just had a funny, actually very frustrating thing happen to my T400. I was using the dedicated graphics, with the laptop unplugged, the battery was at about 15% charge. I closed the screen, the system went to sleep after 5 minutes of inactivity. About 20 minutes later I open the laptop and wait for the screen to turn on. The screen flickers, goes black, and stays black. Usually after 5 or so seconds the desktop shows up like normal, but this time the screen was almost entirely blacked out. It was as if the brightness setting was turned way lower than the minimum. You can just barely make out whats on the screen, but only by turning the screen at an extreme angle and putting your face 2 inches from the surface.
I've tried restarting, switching to the integrated graphics, adjusting the brightness settings, and plugging in the AC, all to no avail. I've looked on google for other similar problems but I've come across nothing like this. Anyone know whats going on? Am I going to have to send this in for service (/sob)?
Any help would be appreciated, I'll post in notebookreview's forums as well.

Just tried plugging in an external monitor, and it worked. So maybe that rules out video card issues? Anyone seen this before?

W540 stuck on ThinkPad splash screen

I've got W540 (32GB RAM, 500GB HDD) running Windows 7.1 64bit that is constantly getting stalled at the ThinkPad splash screen during powerup.
It will often stall at the "ThinkPad" splash screen.
Other times it will stall at the "ThinkPad" splash screen with the "To interrupt normal startup, pess Enter" message displayed.
I've seen other entries that reference this issue with:
- using a SSD, I'm a standard HDD.
- a broken USB port. Mine all look OK (is there a way to actually test them?)
I've updated to the latest Bios and reset the Bios defaults with no change.
I've run the hardware diagnostic tests and found no errors.
When I say "stall" on the splash screens I sometimes find if I leave it alone long enough (maybe 5+ minutes) it will continue to the normal Windows boot up.
This is the 2nd W540 out of a pool of laptops to display symptoms similar to this.
Anyone got information on what may cause a stall at the ThinkPad splash screen?
Thanks.

Not knowing your exact set up, but KNOWING that this is a blind black box with no activity light like a normal workstation, you need to do workarounds.
Normally, on my older workstation, I could see the HD light blink and the rate would give me an inkling of the process.
The WORKAROUND: we now need to calibrate your computer clock to your watch, or use a cell phone time keeper which would already be synced if the W540 is connected to the WiFi (no switch so the W540 has to be connected, unless there is no access point). As an aside, I have found that when there are large MS updates, like last Tuesday, or other such WiFi connected updated, the compute also hangs with the user having NO KNOWLEDGE that the WiFi is talking / or calling home to some cloud device.
Back to the workaround: Boot the system, and when there appears to be a crash or hang in the sequence, note the time of the 'event' and also note the time when it appears to restart. Once properly booted, and I cannot tell you how often this has happened to my W540, check the even times in the [Event Viewer]. Too long to explain, Google the term "Win 7 Event Viewer", or check this:
MS Help - Event Viewer
Then find out where the computer chokes and restarts by checking the time in the events and the cause. These are i/o routines which the Lenovo Gods have decide to shield us from such WORKSTATION task.
FWIW, often I get <Program Not Responding>, when in fact it is performing a numbers intensive task.... yet I cannot tell what is happening as there is no i/o light. Usually unlocks when the task is finished, which may be what is happening on your system. You need to find out the task that is causing the wait.
Odd, the Lenovo Gaming machines Y50 have these lights, albeit atrophied: see lower 4 indicator lights....

T400 Screen turns Black/Gray and System Freezes.

My screen turns black or gray and the system freezes.
The only way to fix it is to restart the system by opening all forms of power supply (adaptor and the battery).
Sometimes it works fine for a day or two, sometimes only for a few hours.
I think the problem has something do with my graphics drivers or some other driver from Lenovo.
I have used Lenovo Thinkvantage Toolbox to check for hardware errors and it shows that everything is working fine.
I have updated all drivers but still the problem is there.
I still have warrenty period left.
I bought my system 2 years ago and have never had any problem untill this one.
My system specifications are given below.
Model: Lenovo Thinkpad T400 2764 CTO
BIOS version (Latest?): 3.18 (latest)
OS loaded (ex. Win 7 64bit): Microsoft Windows 7 Ultimate 64-bit
Lenovo default OS: Microsoft Windows Vista Basic 32-bit
Updates from TVSU completed? Yes.
Updates from Windows Update? Yes.
Power Manager Version: 3.25
RAM installed (brand and 1 x 4gb, 1 x 2gb, 2 x 2gb?) 2 x 2 GB
Model of discrete card: ATI Mobility Radeon 3400
Any error notification? No
3rd party application installed for the graphic card? No.
Any particular application which is running on the time this issue arises? No.
Running on battery? AC? Docked on station? Error occurs in any state.
Any solutions?
Anyone had similar problems?
Thanks.

My problem seems to be similar. Sometimes my screen also turns black unexpectedly and the notebook freezes completely! In some cases I see a bluescreen of death and in some very few cases it restarts automatically. If it does not restart automatically I have to hold down the power button for some seconds to turn the notebook completely off (so that the "power on led" left to the "battery led" is not illuminated any more). Thereafter it is possible to start the notebook again. So unlike user 400 I do not have to remove any connected power sources.
The issue seems to occur out of nowere and seems not to be related to the use of a specific software. My system is up to date with lenovo drivers and windows update, exept the BIOS, which I updated the system two times since the problem exists since more than half a year!!
I also give my system specifications below:
Model: Lenovo Thinkpad T400 2767 WC8
BIOS version: 3.16
OS: Windows 7 Professional x64
Updates from TVSU completed? Yes. (exept newest BIOS)
Updates from Windows Update? Yes.
Power Manager Version: 3.25
RAM installed 2 x 2 GB (bought and placed by loenovo reseller)
Model of discrete card and integrated card: ATI Mobility Radeon 3400 and intel mobility 4 chip
Any error notification? yes, entry for bsod or kernel-power-issue in the system protocol (but no specific error)
3rd party application installed for the graphic card? No.
Any particular application which is running on the time this issue arises? No.
I use my notebook with AC connected, with battery and most of the time in the advanced mini dock! Since a few days the error never happened when the notebook was docked! So I thought it is a power issue or has something to do with the graphics card.
But now I found out, that the issue might be related to the wlan card! This is because I never had a wireless lan connection when the notebook was docked, since I use a LAN cable. But a few days before I had to use the wlan while my notebook was docked and the error occured after some time. Furthermore, as far as I remember the issue never occured when the wireless lan was switched off and not docked, but I will check that again.
The issue also never occured when I booted windows in safe mode.
@400
Maybe you can check if it is the same for you with your wlan? Maybe together we can find out what the exact problem is. I want to find out what is the problem to get it fixed by lenovo. Until now they alwas said, that they had never experienced such an error.
Please keep on reporting.
Thanks for any help

Problem to come back from sleep mode in Lenovo Thinkpad T400 using Windows XP

Problem to come back from sleep mode in Lenovo Thinkpad T400 using Windows XP. Each time closing the T400 lid and try to make the laptop into a sleep mode for some time, it does not properly come out of sleep mode. Login screen is able to see when opening the lid for the first time, but it only seen for a while before then a black screen on T400 Thinkpad appears. Sometime the hard drive activity can be shown also. And then, to come back I had only one option to hard re-boot.
I tried Fn+F4 and power button once to come back but no use.
Please provide me some solution for this?
Thanks in Advance.

oh sorry and its been closed inbetween uses. When i open it the keyboard doesn't light up and it makes no sound.

T400: Screen resolution is mixed-up

I'm using a 2765-21G ThinkPad T400, with Microsoft Vista Business as the OS. I'm using the highest screen resolution, which was native to the PC when I bought it (although I did change the DPI from the default 96 to 106).
Since the PC downloaded the latest batch of Windows updates the other day, certain applications (e.g. Skype, BBC iPlayer download manager, etc.) - as well as Windows message boxes and the ThinkVantage menu - seem to appear at a lower resolution, with a soft/fuzzy appearance to the writing and graphics. This is the case even though everything else remains at its normal, sharp resolution.
It's not the biggest problem in the world, and if I hadn't just paid full-whack on a premium laptop I might just let it slide. But as it is, I'd quite like to find a solution. Anyone got any ideas?

disable your all startup messengers,like yahoo msn google skype and all. may be display driver is get clash with other program..i got this kind of issue in my laptop. use msconfig to disable startup programs.

Thinkpad T400, Win 7 Pro 64bit and sleep

I have a ThinkPad T400 laptop that is running Windows 7 Professional 64bit with SP1. I use a docking station with it as well. When I go home at night, I put the computer to sleep, undock it and take it home with me. On most nights, I don't do anything else with it. When I come in in the morning, I put it in the dock and start it up. However, when I do this, it takes about 5 minutes for the logon screen to appear and another minute or two before I can actually do anything. I've tried different docks with the same result. It isn't hibernating either. Any ideas what may be causing this? I thought Windows 7 was supposed to be fast to resume?

I tend to agree with the suggestion that it's waking from sleep and hibernating. It is at least a strong possibility.
Does it say "resuming windows"?
OTOH, 5 minutes plus is way too long for a normal resume from hibernation. I just tested my T400/Win7 Pro 64. It takes 30 seconds from power on (resuming from hibernation) to the desktop. I don't require a login on resume.
I don't have SP1 installed. The graphics driver prevents that for now.

Thinkpad T400S (multitouch) Vs. MacBook Pro

Hello,
I am recently going to purchase a labtop (for work) and am undecided between the Lenovo T400 S (multitouch) and the Mac Book Pro.
Advantage Thinkpad (previous experience)
- My last past 3 laptops are Thinkpad (no defect what so ever)
- Reliable & Strong (I saw about 3 months ago my baby girl (2yrs) standing on the labtop, & it still works )
- Multiple OS (Windows and Linux) support
Advantage MacBook
- Sleek design (Beautiful)
- MAC OS + Other OS (Windows, Linux, Unix) Compatibility
- Presentations style are great
Both are very similar in price (MacBook Pro = Thinkpad +200$ )
Configuration for both are similar:
- solid state drive
- WiFi/WiMax
- processor very similar
MacBook advantage:
- wider screen
- led screen
- bigger solid state drive
T400S advantage:
- multitouch
Questions:
1. Can the T400S support Mac OS? How about Linux (Debian)?
2. How strong is the casing compared to MacBook Pro or other Thinkpad?
3. Multitouch compatibility with which OS (Windows, Linux, Unix, MacOS)?
4. What type of SW works with this multitouch? CAD applications? Google Earth? Office applications? Vi editor?
5. Can this labtop (in theory) run all these applications: http://www.youtube.com/watch?v=89sz8ExZndc
Thanks
Gus

1. It probably needs some work around to do so, but it is not natively supported out of the box.
2. Well you can drive a truck over it, and still relatively undamaged in the hdd, motherboard, etc.... LCD is cracked. Don't think you can do that on a macbook pro. Even dropping a macbook pro is not advisable since the hinge on every generation of Macbooks are so fragile, dropping them could cause the cable in these hinges to break.. oh there is not much adjustability in the Macbook Pro screen hinges, so it can go through the 180 degrees of movement like Thinkpads can.
Oh Macbook Pro have built in battery, and anyone whom ever use laptops and that knows, built in battery is headache, when you need to replace them. And from the past, you can't really when Apple products battery would decide to kick the bucket on you.
It also doesn't have docks. When Macbook Pro dies, it dies, whereas Thinkpads you can take it apart and service themselves relatively easily, and use various parts from other thinkpads to resurrect it. Bit like Frankenstein.
Thinkpad T400s isn't suppose to directly against Macbook Pro, since there are T400 and T500, W500 and W700 to do that.
T400s is basically a X301s with bigger screen, more expansion slots and dock connector (Macbooks don't have them).
Macbook Pro are well designed machines, but they are restrictive in terms of aftermarket parts, serviceability and upgradability. I would also say reliability with Macbook Pro past certain years of use are not great.

T400 screen flashes then goes black

As the thread title says, my lenovo t400's screen recently started flashing. It wasn't that bad at first but it increased in frequency and started to be very annoying. I noticed changing from battery to cable would temporarily stop it, also turning down the brightness helped.
However the problem started getting worse and now when I am forced to have it on the lowest brightness settings. If I turn it up it starts flashing erratic and then the screen turns off. The system itself keeps working though and if I turn the laptop off or in sleep mode and then turn it on again the screen "works" again (still with flashing). Ofcourse if I left the brightness above its lowest level it will instantly go black again.
Also most likely related, half of the screen (left side) has taken on an "redish" collor.
What could be the problem and is it something I can fix myself?

On the back it says type: 6474-B84. I assume you mean that?
And yes if I were to shine on the screen with a flashlight I can see the content.
Correct, these are the original specs of the machine:

P8600(2.4GHz), 2GB RAM, 160GB 7200rpm HD, 14.1in 1440x900 LCD, Intel 4500MHD, CDRW/DVDRW, Intel 802.11agn wireless, WWAN option, Bluetooth, Modem, 1Gb Ethernet, UltraNav, Secure Chip, 9c Li-Ion, WinXP Pro
I can think of three possibleculprits, LCD cable defective, inverter defective or LCD panel's backlight defective. The cable and the inverter will be cheaper to replace, the panel will be more pricey I guess, (I don't know the current LCD panel prices).
T400's came with standard CCFL and LED screens. You need to find out which one you have. You can try the part lookups page from Lenovo and follow the instructions here: http://support.lenovo.com/en_CH/product-and-parts/partsLookup.page?
(You need the machine type and your serial number, please don't post the serial number here in the forum)
P.S.: If you have a LED screen cluprits could be the cable or the panel, no inverters there AFAIK)

ThinkPad splash screen

Is there a way to disable the ThinkPad splash screen during boot up? I checked out the BIOS settings on my T400 but to no avail.
Thanks

I disabled a few things under the BIOS that I wasn't using and a few things within Windows mentioned here..
http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/What-is-the-Rapid-Boot-extreme-feature-on-T...
So far, it went from a 28 second bootup to about 20 seconds (I'm also using an SSD). The shutdown time is about 5.8 seconds. At this point, I'm pretty content with the progress now.
Thank you all for the comments.

Thinkpad T400 and frame buffer 1440x900

Hello!
I can't get the frame buffer working at the native resolution 1440x900 on my Thinkpad T400.
Have added the vga option at the kernel line in Grub.
kernel /vmlinuz26 root=/dev/sda6 ro devfs=nomount vga=0x355
Have tested with 354, 355 and 356. The screen just goes black.
Here is some info I used.
http://en.wikipedia.org/wiki/VESA_BIOS_Extensions
Orjanp

If you have an nvidia card, try vga=0x365. That's what I use on my Dell laptop with a Quadro NVS 135M driving a 1440x900 screen.
Failing that, use vga=ask and it will give you a list of all the modes the card you have supports.

T400 screen - loose connection

Dear All,
The screen of my Thinkpad T400 has started to act weird the last couple of weeks. As far as I can tell, it seems to have a loose connection as it goes dark if the hinge is not in a specific angle where the connection is working fine.
I have been searching around thius forum and others but without any luck. However - I found a video on youtube with someone who has the same problem: http://www.youtube.com/watch?v=0O2cx9T4DI8
Does anyone know how (if possible) to fix this?
Regards,
Jakob - Copenhagen
Solved!
Go to Solution.

I can think of the cable being loose, or the connection to the mainboard.
If you are not afraid of opening your laptop you can download the HMM (hardware maintenance manual) from here => click me! and remove the battery, palmrest and keyboard bezel following the instructions from the manual. Then check the lcd to motherboard connector as shown in page 117 of the manual (not page 117 from your pdf reader!)
If that doesn't change you may need to check the connection of the cable to the LCD, this means more dissasembling, but let's try the motherboard one first.
Hope this helps!
Cheers

Problem with 3rd party RAM for Thinkpad T400

Hey everyone,
I just installed 1GB Hynix RAM (came from my macbook pro) onto my Thinkpad T400. At first, it booted up fine. I did all the memory tests and everything. No problems found.
However, every once in a while, when I reboot my laptop, the bios beeps once, three times, once, then three times. I looked up the beep codes and called customer service and it has to do with the memory.
Sometimes when I press the power button, the laptop turns on but the screen doesn't. I just have to force it to shut down then restart...then it's fine.
Any suggestions? (besides buying overpriced lenovo branded RAM)
Thanks in advance.

gatorman1122,
umm, i think we've already established that it's DDR3. it's absolutely impossible to make DDR2 modules work in your system even if you removed the check pin from the socket. and, even if you did get it to fit, your system wouldn't even POST. the pins are different in both quantity and mapping.
what hasn't been established, however, are the exact specs (not the type) of the module installed. what speed is the module? what's the part number? is it an original apple module or an aftermarket? again, more info is needed on what you installed.
also, what beep code are you getting? is it the beep code for memory or for something else? you can check codes in the T400 HMM if you haven't already.

The installation CDs of my thinkpad t400

Hello all
I have a problem. I have a thinkpad t400, but I don't have the installation cd's to reinstall the basic programs of the system-
Is it possible to get them somewhere, to buy them or to dowload them for lenovo?
Please I need some help ! did somebody knows where to get them

If your T400 is currently working and still has the Lenovo factory stuff installed - and you haven't changed your hard drive partitioning, you can burn them yourself. It will be called something like create recovery media, or create factory recovery media.
You only get one shot at doing this. If you've already burned a set and lost them, you will have to get them some other way.
Depending on your version of Rescue and Recovery it may be an option on the advanced screen, or perhaps as a selection in the "create rescue media" option on the advanced screen. Or perhaps as an option in the "back up your hard drive" option on the advanced screen.
Another way (if it's still there) is to click on the Q partition in windows explorer. You should be offered the option to create recovery media.
Sorry I can't be more specific. My T400 is running a clean MS install with the Lenovo tools added, so I can't quite duplicate a factory setup for reference.
If you need the disks to repair an already damaged OS, you'll have to get them from Lenovo as Maliha says.
