T500 no display

My display on my faithful T500 has stopped working.  Connecting an external monitor yields no results either.  Is this a sign the video adapter has passed on?  Is the video adapter embedded on the motherboard or is there a daughter board I can replace?
BTW, no audible beep heard during startup.

Some other tests you can try...
remove battery and ac power and cycle power button ten times holding a few seconds each and 30seconds on the last, the using ac power only see if you can get it to post, then repeat with only battery and with both.
Try abusing the keyboard and see if you can get it to beep, this as well as the "no ram" test could indicate there is some life in the board, but it won't tell us exactly what the problem is. 
ps. This topic will probably be moved to the T500 section soon.

  • R400/T400/T500/W500: display driver "amdkmdap" crashes

    Executive summary: All current Lenovo ThinkPads with switchable graphics (R400, T400, T500, and W500) have usability issues in connection with Vista and the use of external monitors. For more than half a year, users were plagued by frequent Windows crashes. During that time frame, Lenovo did not comment on the various available reports and complaints. By the end of April 2009, Lenovo resolved many issues by releasing a new official driver. Though several problems, including severe ones, remain as of today. Lenovo has said to be actively working on the remaining issues (without outcomes so far).
    Important information for affected users: If you're having one of the issues reported here, then Lenovo advises you to call your local Lenovo Support. Demand that a case is submitted to hardware engineering. In particular, you should ask for "a CMVC case to be created and escalated". Using these "code words" ensures that your case is properly addressed.
    Old problem description
    On Vista 32 and Vista 64, the ATI display driver "amdkmdap" crashes when an external monitor was active before OR an application (game) using DirectX technology is used. The user typically receives a couple of so-called "Timeout Detection and Recovery" (TDR) messages from Vista:
    (Click here for an explanation of the message from Microsoft)
    Sometimes, amdkmdap crashes several times in a row. Then Windows crashes with a so-called "BSOD", likely resulting in data loss. Typically, Windows detects "atikmpag.sys" as the crashing driver. Sometimes, also an instantaneous reboot happens independent of prior TDR crashes. In such a case, no BSOD is displayed.
    The following movie illustrates the phenomenon: http://www.youtube.com/watch?v=LBX9QsCmrpY
    This behavior above has been confirmed for the following ThinkPad models: R400, T400, T500, and W500 (see below). Problem reports indicate that the symptoms are often related to playing games and/or the notebook being docked and the external monitor being connected via DVI.
    Though, the presence of these two conditions is not necessary to trigger the driver crash:
    There are reports where no dock was involved and the external monitor was connected directly to the notebook's VGA port.
    Furthermore, there are reports where the notebook was docked and an external monitor was connected to the DVI port.
    So far, there has been no report relating to a monitor being connected to the Display Port which is available on some models. (Possibly because this port is not used.)
    There are a few reports where neither a dock nor an external monitor was involved.
    Playing certain games reliably triggers the crash.
    Steps to reproduce
    While intially (around September 2008 - October 2008) the crash could be triggered easily, the situation is now (December 2008) more complex. The crashes do still occur, though there is no clear pattern anymore. According to various reports, the display driver crash can be triggered as follows:
    Resuming from standby
    Watching a DVD.
    Playing one of these games: Fallout 3, Bioshock, Team Fortress 2, Knights of the Old Republic.
    Arbitrarily during normal work. On a normal working day, the problem occurs at least once.
    Further issues
    Here are more issues which seem to be related. More information can be found in other posts of this thread:
    The notebook display and/or the external monitor runs at a low resolution after resuming from standby.
    After the login both monitors flicker while adjusting the resolution of the monitor.
    The external monitors cannot be activated using Presentation Director.
    The external monitor is blank after docking or undocking.
    There are some reports about display driver crashes on machines running Windows XP.
    The switchable graphics drivers limit the useable RAM under Vista 32 to 2.5GB (i.e. 500MB-1GB less than usual).
    Workarounds
    Lenovo has released a new "tip" document which provides a link to a new driver. Get it here but be sure to read the instructions!
    (Old tips follow below the line. Consider them as obsolete.)
    Here are some tips which might make the problem occur less often. I have not tried all of them. Though, A. and B. have improved the situation for me; your mileage may vary.
    A. If you do not have to use an external monitor, then switch to Intel graphics for time being.
    Otherwise:
    B. Make some changes to your system:
    Disable Aero.
    Create a new profile in the power manager with the following setting: When running on AC, turn off the monitor after 40 minutes. (Thereby, the notebook goes less often to standby.)
    Install the newest graphics drivers.
    Install the newest BIOS.
    Install the newest Hotkey utility.
    Install the newest drivers.
    C. Disable the switchable graphics in the BIOS setup and install modded drivers from ATI (see zilla's post in this thread for instructions).
    The last workaround (C.) has been confirmed to work reliably by several users. Though, thereby you use drivers which have not been tested by Lenovo. It's possible (but not very likely) that damage results by doing so. Also, it might be difficult to install a future Lenovo driver which resolves the issues reported here. Finally, you cannot use the power-saving Intel graphics. Thus, you should only use this workaround if you know what you are doing.
    The programs can be downloaded from the following locations. Notice that System Update does not always offer you immediately the lastest versions.

    Original post
    Hi there!
    I have major troubles using a Dell 2709W monitor with my T400. 
    The notebook is attached to a Advanced Mini Dock to which the monitor is connected via DVI.
     The problems are as follows.
    A. Activating the external monitor often fails
    Steps to reproduce:
    1. Attach a Dell 2709W via DVI to an Advanced Mini Dock which is connected to a T40
    2. Start Windows and make sure that the T400 is running on the ATI card.
    => Dell monitor enters power saving mode because no signal is coming.
    3. In Windows use either the Presentation Director, Windows, or the ATI tools to activate the Dell monitor.
    Expected result: The Dell monitor is activated and the Windows desktop is shown on it.
    Actual result: It takes 1-3 seconds for the Dell monitor to display something. The monitor shows the Windows desktop for a short period. Then it's black again and the monitor returns to the power saving mode .
    Analysis: It seems that the Presentation Director, Windows, or the ATI tools (or more aptly, I guess, the ATI driver) expect a quick response from the DVI-port that a monitor is present. If they do not receive the response, the DVI-port is deactivated again. Since the monitor is too slow to respond and enters the power saving mode too quickly, the monitor can hardly ever be activated.
    Suggested change: Change these tools (or the ATI driver) so that they wait longer for a response on the DVI-port.
    B. Resuming from monitor sleep causes Windows to fall back to a low resolution if the Dell monitor was activated before
    Steps to reproduce:
    1. Attach a Dell 2709W via DVI to an Advanced Mini Dock which is connected to a T400
    2. Start Windows and make sure that the T400 is running on the ATI card.
    3. Select the Energy Star profile
    4. Activate the Dell monitor
    5. Don't use Windows until the notebook display and the Dell monitor are set to sleep by Windows.
    6. Wake up the displays (e.g. by pressing some keys)
    Expected result: Both displays are run in the display mode as before.
    Actual result: The Dell monitor still sleeps. The notebook displays is run at a lower resolution (I guess 800x600). The Windows login prompt is not visible and it has to be guessed that it is shown. Though the typical Windows login background is visible. If the password is entered, then Windows can be used again. Though, the resolution is still low and the Dell monitor still sleeps.
    Analysis: It seems that by sending the Dell monitor to sleep, the monitor deactivates the DVI-interface or enters a low-power interface mode. This seems to disturb some component in Windows (the Presentation Director, Windows, the ATI tools, the ATI driver) in a way that Windows only activates the notebook display when it resumes from "monitor sleep".
    Suggested change: Change these tools (or the ATI driver) so that they can cope with the situation that the DVI-interface is deactivated and wait longer for the interface to be in a useable state. Reactivate an external monitor even if it "sleeps very deeply".
    Relevant system information
    - T400 2767-CTO (T9400, 2x2GB RAM, ATI, WXGA+ LED)
    - Advanced Mini Dock
    - Vista 32 Business (German) - fully updated
    - All Lenovo updates via System Update are installed- Dell 2709W
    - The system runs the ATI graphic card in the described scenarios

    Solved!
    Go to Solution.

    Lenovo support made me reinstall presentation director to rule out this component as a factor. After the reinstallation, the amdkmdap-problem is still present. Letting Windows go to standby and waking the system up afterwards, is a reliable method in my case to reproduce the problem on condition that an external monitor was active. The problem does not occur if no external monitor is present.
    A web search for "amdkmdap", "atikmpag","BSOD" with one of the ThinkPad-series names (like "T400") shows that other persons also have this problem with R400s, T400s, T500s, and W500s:
    - t400: Display driver crashes
    - W500 Display Driver
    - My W500
    - T400 Display driver stopped working...
    - T500 Video/Video Driver Issues (2056-4SU)
    - NUS T400 issues
    - T400 Display Driver Issue
    - Vista64 + 4GB RAM + External Display = BSOD
    - R400 problem report (in Chinese)
    - T500 problem report (in Chinese)
    - Bioshock keeps crashing (seems related)
    -  Vista x64, ATI graphics, dock + external LCD = bluescreens? (a report by a W500 user)
    - many problems with lenovo w500
    - another R400 problem report (in Chinese)
    -  Vista BSOD on Lenovo T500 with new Switchable Graphics
    - switchable graphics and external monitor through port replic
    - Problem with Lenovo T500 notebook & external LCD
    - Lenovo ThinkPad T400 - some impressions.
    - T400 freezes with graphics Intense programes
    - Standard Laptop mit ein paar Macken (in German)
    Some possibly related Non-Lenovo cases: 
    - Why Vista crashes so often when dual display is enabled?
    - Vista and 7.3 Display driver atikmdag stopped responding error
    - 4870 vista x64 multi-mon = atikdmag BOOM
    In the cases in which people observe the "amdkmdap"-problem and describe the circumstances, the use of an external monitor is always a factor. These other reports also indicate that it is likely not an issue with the hardware of my notebook (or then a general problem for many batches of these machine types). For it happens a) on many systems and b) on different kinds of systems.
    If others want to contribute to the problem solution, then we should provide Lenovo and ATI a good problem description. So, please add your description.

  • T500 With Display Port TV Hookup

    I'm starting a new thread here because the other one dating back to January seemed to have gone cold. Hope someone can help with a solution. 
     I am going from T500 display port to HDMI via an adapter cable and have my audio cables attached to audio ins on the same TV  input as the HDMI. (It is my understanding that the HDMI/display port on the T500 does not support audio.)  I can get sound or picure but not both. Whenever I plug  the HDMI cable into the  TV,  the audio is diabled, unplu HDMI and audio returns. I spoke to Sony (my TV brand) about this at length to someone I think was about as qualified as  the Lenovo techs about my problem and she finally said I needed to change audio out on computer to analog. I  do not know how to do this, probably do not think it necessary and last think it was her way of saying goodbye!
    Anyway, I still have the problem. I have connected previous computers through s-video and audio cables and that works fine but, alas, my Lenovo has no s-video.  I would welcome your insights or at least a little intelligent conversation about this.
    Thanks, Dave

    Does it work if you plug it into a different source? What if you plug the cable directly into the T500's onboard DisplayPort?

  • My T500 external display colour issue

    Hello all,
    Before I invoke my warranty on my laptop I thought I would try here first.  My external display all of a sudden today, started to turn yellow.  It seems like its random as to what exactly is being turned yellow, but it seems like almost every part of the screen is effected.  Some facts:
    1.  I have tried 2 different monitors and 3 different VGA cables with the exact same results.
    2.  When I first plugged the monitor in today and set it to output only to monitor, the screen was fine, when I changed it to 1680x1050, the yellow instantly showed up
    3.  Whatever resolution I try now, its always the same
    4.  I have rebooted, tried extended, clone and one screen displays, I have even tried rotating the display!
    So thats the story, my gut feeling says the video card in the laptop is the issue, but I do not know enough about it to be sure.
    Anything anybody can think of that I can try before calling it in?
    Cheers,
    Darren

  • T500 - poor display quality

    I have T500 with WXGA TFT LED Backlight and integrated Intel graphics and I'm very disappointed with it. This LCD
    presents very poor quality in terms of viewing angles (not only vertical but also horizontal), colors (they are somehow
    washed-out, not saturated) and contrast.
    Does anyone know if it is possible to replace this display with WSXGA+ TFT CCFL Backlight or WXGA TFT CCFL Backlight.
    Will they give better results?

    If you would like ThinkPads with better displays, might I suggest that you please take the survey?
    Thanks!

  • T500 fuzzy display after Fn+F7

    I have switched to a T500 with Windows XP.
    When I use a projector and hit Fn + F7, the projector displays the image clearly.
    However the display on my T500 becomes fuzzy.
    Does anyone know if this is normal?
    I have tried changing the display setting, but it did not help.
    My colleagues also experience same problem.
    Sometimes after Fn+F7, the display on the lapto zooms in.
    Any suggestion would be appreciated.
    Thanks!

    I believe the reason you are seeing a blurry image is because your display adapter (video card) changes the resolution of your screen in order to match the resolution of your projector. Because your LCD screen's resolution is much higher than the projector's, the screen will temporarily become blurry until you unplug the video cable. You can otherwise use a lower resolution that your LCD can handle and perhaps that might improve clarity.

  • T500 hotkey display?

    Hi,
    So I just got a T500 on wednesday.  I must have updated something today that doesn't show the display when I change my volume settings using the keyboard volume buttons.  The green display also doesn't show when I change the brightness settings using hot keys.  Everything but the mute seems to work, and the display doesn't show.  What's going on?  I have Vista Business.  Thanks!

    Hello,
    please try to download Lenovo System Updater, if you have XP than you´ll to install need MS NET 2.0 before.
    But beware! Only update the hotkey driver package, not the bios updates or R&R or CSS updates.

  • T500 display very dim , possible mechanical failure?

    Hello,
    It seems that my T500 LCD display has become very very dim, the display is barely visible.
    After repeatedly turning it on/off it suddenly was able to display full brightness during one debug session... I even restarted it / shut it down multiple times, and it worked. HOWEVER, it seemed that the brightness was dependent on the angle at which the LCD was hinged, if I opened it all the way the screen became bright again (something over 90 degrees), if i started to close it (roughtly 30 degrees?), it became very dim. To me this sounds like a mechanical issue, possible a loose cable. Unfortuantely, I was not able to reproduce this again after this debug session, I suspected that as i was transporting it to/from work i may have changed some internal mechanical configuration.
    Is there an actual 'mechanical' switch which drives the LCD brightness depending on the angular position of the LCD? I tried reading through the service manual here:
    http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mob​iles_pdf/43y6630_04.pdf
    I couldnt find any mention of any sort of LCD brightness mechanical hinge switch
    === other info===
    From googling, the issue could also be :
    a) inverter issues
    b) backlight issues
    c) fuse on mother board?
    As a quick test, i hooked up the VGA output to a secondary monitor and that works fine, so long as I go to the BIOS and set it to boot to the VGA first as the primary display.
    Any suggestions would be great!

    Try going into the BIOS and switching to Integrated Graphics only. Does the screen still remains dark/dim?

  • T500 Specs

    Are the published specs for the T500 video display wrong T500 (See http://shop.lenovo.com/ISS_Static/merchandising/US/PDFs/t400_and_t500_datasheet.pdf )?  The information shows both of the available video modes having the same dpi even thought the resolution is different on the same physical sized screen.  Shouldn't the WXGA DPI be about 98dpi?

  • HELP : T500, External LCD monitor problems, after upgrading GMA4500MHD display driver!

    I have upgraded my display driver for GMA 4500MHD from version 7.15.10 to version 8.15.10.1968 (Vista 32bit).
    After the installation and rebooting of the T500, my brand new Samsung SyncMaster2233BW cannot show correct display image.
    Only image I can see is white screen with few blue shapes. I'm using VGA output for connection. I have tested the monitor by connecting to my other laptop (Dell D620) and everything works fine.
    Can somebody help with this strange problem? How can I make my external monitor work again with
    T500? Is it possible to find and download display driver version 7.15.10.xxxx somewhere and revert back?
    T500 configuration: 15", 3GBRAM, 320GB HDD, Vista 32bit (Home Premium, SP2)
    HELP, HELP, HELP

    Hi sehu,
    Can't you just ask Windows to roll back to previous installed driver? Additionally, have you tried going back to the point where previous version of driver was installed through Windows System restore?
    Also check in c:\swtools\drivers\video folder to see whether or not the desired driver resides there.

  • Jumping Display T500 Switchable Graphics

    Hi guys
    So my dear T500 that has servered me so well over the past 4 years all of a sudden developed the weirdest graphics glitches that were definitely hardware related, as they happened even in the BIOS screen. So I had the mainboard changed and all seems well except.....
    The machine dual boots between Windows 7 64bit Ult and Debian Jessie with XFCE. In Linux (and with Fedora and Ubuntu live USB boots) both cards work flawlessly.
    In Windows the AMD card works flawlessly. The Intel card however causes the display to jump left and right, kind of like you grabbed the picture at the bottom left of the screen and pulled it outwards and then let go - constantly - to the point where you cannot see a stable display at all.
    This error only happens in Windows when the driver loads. No issues in BIOS screen or the Windows booting screen. If I change the display frequency it changes the severity of the effect. If I change the display resolution to anything lower than native 1680*1050 it works fine although obviously the text and graphics look like crap at non-native resolution.
    This machine has a replaced mainboard. The RAM has been changed. I am now completely clueless as to what could be the cause. I'd really like to fix it as I love this machine and it serves me very well as a backup deveopment machine etc etc
    Any help greatly appreciated
    Thanks in advance

    You'd have to replace the CPU to be sure.
    If it was screen related, it should be failing the same way with the discrete card too. You might want to double check the screen cable and connectors though. Do be very careful and 100% ground yourself. The T400 and presumably T500 has a really sensitive backlight fuse.

  • ??? iMAC 2012 27" used as display for LENOVO THINKPAD T500 ???

    I have a Lenovo Thinkpad T500 (must use for work) and my home computer is a 2012 iMac 27". I would liek to use the iMac as an external display for my thinkpad. I've read everywhere online and haven't found the answer I'm looking for!
    I bought a displayport TO minidisplay port cable (both male ends) and connected the imac + thinkpad. Executing CMD f2(displayport activating function) does nothing though. I've tried fn+CMD+f2 etc..etc..  I've read these cables can go BOTH ways... (but have also read some only go one way?) The thinkpad has a dvi output as well but I was hoping to use this DP/MDP cable to connect the two computers as it seemed more logical than using the old DVI/VGA formats...
    Has anyone got any experience doing this or anything that might help me solve this dilemma.
    Thanks for your time!

    Hi, if it doesn't have a real MiniDisplay Port, I doubt the adapter has what is needed to do it from what I've read.

  • T500 display port

    I have a t500 model 2081. I can't seem to find a user manual that tells about the display port. I want to connect my display port to my tv by an hdmi cable.
    1.Does my computer support display port to hdmi?
    2. Is there a way to do the conversion? (lenovo has a cable to dvi but I don't see one to hdmi)

    Hi tom2009,
    Welcome to the Lenovo forum 
    If you Google displayport hdmi cable you will see many options. I'm using a DisplayPort-DVI-D cable right now with my T500, it works fine. DVI-D and HDMI are the same electrically, except for the audio signal. You should have no problem driving HDMI video from your T500 with the proper cable. Audio, I'm less sure of; maybe somebody else can chip in?
    Good luck,
    Frank

  • T500 display adapter problem on Windows Server 2008

    Hello,
    I recently got T500 and if I understand this correctly, it comes with two display adapters,
    - ATI Mobility HD Radeon 3650
    - Intel Mobility 4 Series Express Chipset Family.
    I installed Windows Server 2008.
    Now my problem is that I can't install ATI Mobility HD Radeon 3650 driver but only able to installed Intel Mobility 4 series Express Chipset Family driver.  Funny thing is that I tried to install the ATI Catalyst Manager, but it's not installing.  I know it is not installing because when I right click on the desktop, I don't see an entry for "ATI Catalyst Manager" and if I go to C:\Program Files\ATI Technology folder, it is empty.
    My another problem (main) is the screen turns itself on/off several times and I get "display driver igfx stopped responding and has successfully recovered" error message, and then I see a "fuzzy screen" which requires me to forcefully shut the computer off (by pressing power button).
    I tried to install the driver manually on Device manager, but still no luck.
    Anyone had same problem and maybe have a solution?
    Thanks. 

    how did you install the drivers? lenovo-download drivers doesn't necessarily install themselves, but annoyingly merely extracts them to a folder.
    or, more simply, use system update to install all the drivers

  • T500 Windows 7 - Screen does not display - Switchable Graphics Problem

    Hello,
    I have a T500 and I recently upgraded to Win7. Evrething was fine until I tried to install the drivers for the graphic cards and went on in BIOS and selected to use the integrated graphic card option. After reboot everything turns on except for the display. The fan works, everything looks OK but the screed does not display anything. I even tried to boot directly from the Win7 disk and install a fresh copy (maybe it would have been a better idea to do that in the first place) but it's the same, nothing happens. I don't know what else to try.
    Please help.
    Thank you.

    UPDATE: I just came back after a visit to the apple service provider here in New Delhi. They have replaced the logic board on my macbook pro and guess what? the situation is still the same. No difference what so ever as far as the screen resolution is concerned. I can still see those black bars in the exact same places i.e. the right hand side as well as on the top of the screen. Even the size of the black bars are still the same.
    I am so upset right now. After trying my best in order to solve this problem I went to the AASP with high hopes. I was very confident that after replacing the logic board this annoying problem would go away but unfortunately that's not the case. Even the Apple Engineer was clueless on how to solve this problem.
    I think I'll call apple care and speak to the customer relations regarding a replacement.
    If any of you can come up with a solution to this problem please let me know.
    I'm all ears!!!
