• R400/T400/T500/W500: Switchable graphics issues with Win 7

  Based on the experiences of the wire on switchable Vista graphics driver issues, I here starts a new switchable graphics related to Windows 7 (any SKU) records. Please keep the Center wire and clean up your language. IE: problems related to the XP or Vista are not the subject here.

  I made the switch to Win 7 64 and so far, it is an improvement in the "switchable graphics" - zone. But I have seen some issues:

  • Energy consumption is much higher than under Vista 32. It seems related to a problem in the management of the switching power of graphics adapters: see the thread by roteiro.
  • On my external display of Dell, I sometimes watch "pixel noise". In certain areas of the screen pixels flickering in different colors.
  • Could be related: hang after the release of the standby mode
  
  

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

  Summary: Lenovo ThinkPads with switchable graphics (R400, T400 and T500, W500) have problems of usability under Vista and using external monitors. More than six months, users have been plagued by frequent Windows crashes. During this time, Lenovo will not expressed complaints and reports available. The end of April 2009, Lenovo has solved a lot of problems by releasing a new official driver. However, several problems, including serious, remain as of today. Lenovo said to work actively on the issues pending (without results so far).

  Important information for users: If you experience any of the problems reported here, then Lenovo will advise you to call your local Lenovo support. Application that a case is submitted to engineering equipment. In particular, you should ask "a case CMVC to be created and degenerate". These "code words" ensures that your case be treated correctly.

  Old description of the problem

  On Vista 32 and Vista 64, the "amdkmdap" ATI display driver hangs when an external monitor was active before OR an application (game) using the DirectX technology is used. The user receives usually few messages called "Timeout detection and recovery" (TDR) of Vista:

  

  (Click here for an explanation of the message from Microsoft)

  Sometimes, amdkmdap falls down several times in a row. Then, Windows crashes with a so-called "BSOD", probably resulting in a loss of data. Generally, Windows detects "atikmpag.sys" as the driver to crash. Instant restart sometimes also independent from the front THAT TDR crashes. In such a case, no BSOD is displayed.

  The following video illustrates the phenomenon: http://www.youtube.com/watch?v=LBX9QsCmrpY

  Above this behavior has been confirmed for the following ThinkPad models: R400, T400 and T500, W500 (see below). Problem reports that symptoms are often related to play games or the laptop being docked and the external monitor connected via DVI.

  However, the presence of these two conditions is not necessary to trigger the accident to the driver:

  1. There are reports where no dock was involved and the external monitor is connected directly to the laptop VGA port.
  2. In addition, there are reports where the laptop is docked and an external monitor is connected to the DVI port.
  3. So far, there were no reports related to a monitor connected on the display Port that is available on some models. (Perhaps because this port is not used.)
  4. There are a few cases where a dock, or an external monitor was involved.
  5. Some games with reliability triggers the crash.

  Steps to reproduce

  While initially (around September 2008 - October 2008) the accident can be triggered easily, the situation is now (December 2008) more complex. Accidents happen again, although there is no clear model more. According to various reports, the crash of display driver can be triggered as follows:

  • The output of the mode standby
  • Watching a DVD.
  • Playing one of these games: Fallout 3, Bioshock, Team Fortress 2, Knights of the Old Republic.
  • Arbitrarily during the normal work. A normal working day, the problem occurs at least once.

  Other issues

  Here are several questions that seem to be related. More information can be found in other posts in this thread:

  • The laptop screen or external monitor works at a low resolution after the release of the standby mode.
  • After the connection, both monitors flicker when the screen resolution setting.
  • External monitors can be activated using Presentation Director.
  • The external monitor is empty after the connection or disconnection.
  • There are a few reports on the accidents of display driver on computers running Windows XP.
  • Switchable graphics drivers more than 2.5 GB RAM usable under Vista 32 (or 500 MB - 1 GB less than usual).

  Workarounds

  Lenovo has released a new "trick" document that provides a link to a new driver. Get it here , but be sure to read the instructions!

  (Old advice follow below the line. Think of them as obsolete.)

  ---

  Here are some tips that could make the problem happen less often. I have not tried all the. However, a. and b. have improved the situation for me; your mileage may vary.

  A. Si you don't have to use an external monitor, then move to the Intel graphics card for now.

  Otherwise:

  B. make a few changes to your system:

  • Disable Aero.
  • Create a new profile in the Manager of power supply with the following parameter: when running on AC, turn off the screen after 40 minutes. (And therefore, the laptop less frequently between standby mode.)
  • Install the latest graphics drivers.
  • Install the newest BIOS.
  • Install the latest Hotkey utility.
  • Install the latest drivers.

  C. disable switchable graphics in the BIOS setup and install the drivers from ATI modded (see zilla poster in this thread for instructions).

  The last solution (c.) has been confirmed to work reliably by several users. However, as a result, you use drivers that have not been tested by Lenovo. It is possible (but not likely) that damage the results by doing so. In addition, it may be difficult to install a Lenovo driver that solves the problems reported here. Finally, you cannot use the energy saving Intel graphics. Thus, you must use this workaround only if you know what you're doing.

  The programs can be downloaded from the following locations. Note that update system not always immediately offers you the latest versions.

  Update:

  -Lenovo support informed me today (2008-10-24), they are working on the problem.

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

  I just installed Windows 7 yesterday and of course, he had problems with this video card. I have a T500, bought in March of this year.

  Everything worked fine after installing Windows 7. The problem was when I installed the video driver from Windows Update. The screen initially showed only the wallpaper after installation, and after that reboot the screen would just be black, showing only a cursor. I saw a few posts where someone said that this is because Windows thinks that a projector is installed, so you must press the button of the window + P, and then the right arrow, then enter. But I have not tried. I'm sick of this dang hacking video card!

  Someone was able to get the card works well under Windows 7? Now I'm running it with just the default driver, which works fine until I try to connect an external monitor (it doesn't let me extend my screen).

  If you have installed the driver Thinkpad Hotkey and OSD, you must disable autorun of the on-screen display program. The symptoms you describe are a bit like mine with the same problem

• If FF 39.0 on a new PC with Windows 7 Pro 64 bits - in the sidebar search results bBookmarks are slow - is new facility there a solution for this?

  Recently I've just set up a new PC with Windows 7 Professional (64 bit) as the operating system. I just imported bookmarks from my PC in one. HTML file, I created from my old PC. Now whenever I type a search term in the search box to refine my search for one of my favorites of many, sometimes even by typing in the term search begins to lag while I'm typing more letters. Search term/terms once entered, it seems to take 15-20 seconds before the results list appears. This used to be almost instantaneous in this same version of FF (39.0) on my old PC 64 bit of Windows 7 (Home Premium) to bring up the results. I already tried to install the add-on called "signed 1.3.1 - 0 maintenance of the premises and this time there really doesn't make any difference that it helped when I got FF 38.0.5 on my old PC to Win 7 64-bit." Can it still be addressed. Please update as soon as POSSIBLE with the solution.

  Start Firefox in Safe Mode {web link} by holding down the < shift >
  (Mac options) key and then from Firefox. Is always the problem?

• IE9 does not display graphics at all with two display running drivers.

  Hi all. Thank you for taking the time to read my first post.
  I just picked up my new A660 reception - 1 H 7. For some reason, Internet explorer 9 appears not at all no graphics while two display drivers are running. I have intel HD Graphics and nVidia 310M graphics installed in Device Manager and only when I turn off the nVidia 310 m it doesn't then display graphics in IE9. If I disable the Intel HD graphics card, the entire screen goes completely and I have to force a reboot hard to recover.
  Could someone please explain to me why I have two display drivers? I guess the nVidia card is the most powerful on both but can't make it work independently of the Intel one, if there is a fix for the display problem in IE9.

  Pause to breathe!

  Thank you everso much and I look forward to contribute to this forum myself by helping someone soon.

• How can I apply a new style with an excerpt and DW artifact of the old style?

  Hello

  I use Dreamweaver CS5 in Windows XP SP3. My problem seems simple, but the resolution remains elusive.

  Let's say I'm stuck-in editing the text in MS Word that DW auto-formaté. I highlight text and use a clip to attach the text of the h2.

  Rather than delete the old style and its replacement by h2, DW applies the h2, but copy the old style, enclosing nothing and it bumps to the next line. If the old style included a paragraph tag, which flows into the extra space. For anything.

  Now, this seems to be a minor thing, but it is not so little, when you try to quickly prepare a large document with different header styles. Having to make dozens of changes that, in my view, should be completely useless becomes a burden.

  Is it possible to attach some text in a new style with an excerpt without the old style of stick around?

  Thanks for all the answers!

• New Skype install on Win 8.1 crashes ALL the time

  Hello

  OK - so I see that there are few people complain of similar problems, so here's my problem:

  1. new installation of Windows 8.1 (64) - Dell laptop with 8 G of RAM and INTEL graphics card

  2. before this - the m / c was running an old version of Skype perfectly on Win7 Pro

  3. check all drivers up to date.

  4. all recommended/important updates apply.

  5. installed Skype 6.22.64.104 had to reboot and re - sign in to Skype before my contacts came.

  6 first test - call Echo - right pane goes gray, cursor weaves, echo replies and I can record my voice. BUT no way to put an end to the call that the right pane is still not virgins a GRAY.

  7. after a certain time - bombs of Skype with an exception.

  8 exception and dxdiag that attached in the zip.

  NB my Skype app on an iPad is still running - even IOS 8.1.1.

  Thanks - I hope never...

  OK - so I'm wrong about the 64-bit I guess:-O.

  Just re-installed 6.22.64.106 after uninstalling the version 6.14.

  Thanks for reminding me that my laptop gas also a graphics chip GeForce - bug * d if I know why I need this because I've NEVER played a game on the PC - and I have no intention to do:-O.

  In any case, your comment made me think - WHY Skype is trying to UNLOAD a driver:-O.

  So - I checked the settings of device for the GeForce card Manager and surprise - Windows tells me its dat yo:-O.

  So I downloaded the graphical tool GeForce GeForce 'experience' and IT tells me that my GeForce driver is actuall up-to-date (by YEAR): - O - thank you Microsoft:-O.

  -J' so installed the new version, Skype, uninstalled, reinstalled 6.22 and BINGO - it now works BL * Y!.

  So WHY Skype plans even with some "games graphics driver? By the simple act of switching, it in or out - blocks Skype:-O.

  In any case - folded findgers - his work WITH the latest Skype:-O.

  Hope this might help some other poor S * D ;-))

• Firefox and Nvidea graphics drivers crash at the same time.

  This rare, occurrence in general on Facebook but I think it's just because it's a page I'm often, and that overall the site has no impact on this.

  Sometimes my two drivers graphics and Firefox will crash with the result no entry on my monitor for a few seconds and a dialogue of Mozilla crash and small ball of task bar telling me my drivers have crashed and valued.

  While this doesn't happen often, I am always curious to know why Firefox crashes my graphics drivers sometimes and yet I played many games intense and never had a single accident.

  Graphics card is a Nvidea GTX 460 and drivers in DXdiag version is 8.17.12.8562 and in the popup something along the lines of 285.2 bubble, I'm not really sure on this last because it disappears quickly.

  Also happens on my machine. Accidents cause usually just of my screens only blinks several times, but sometimes it forces me to hard reset my computer because it is not recover.

  With the help of 2 GTX460 SLI. Windows7 64 bit. Latest version of Firefox and accidents have taken place for months with several previous versions of firefox as well. In addition, the latest stable nividia drivers.

  And come to think of it, I think that the accidents began when I installed my second graphics card.

• We bought a new computer with Windows 7. Can I sell the box Windows 7 Upgrade CD that we used for his old computer?

  Computer of my wife is dead, so I did a new one supplied with Windows 7 already installed.  Can I sell the box Windows 7 Upgrade CD I bought for his old computer?  We no longer use this license - we pulled the hard drive of the old computer OS and make it like a secondary on his new computer.  If the license is no longer used by us - or it will never again - but I do not know if someone would experience difficulties to activate if they we bought because I do not know if we can 'turn off' the old license.

  Yes, you can sell it, you will need to inform the seller that they may have to use the phone activation because it was already in use:

  How to activate Windows 7 manually (activate by phone)
   
  1) click Start and in the search for box type: slui.exe 4
   
  (2) press the ENTER"" key.

  Also, I would like to know what is the best practice for backup/restore of the database of physical relief?
  
  Thanks in advance.

  Hello;

  Just an opinion, but I like the book 'Oracle Data Guard 11g Handbook' as the document and the answers to the second question.

  Chapter 12 covers the A to Z of RMAN with Data Guard.

  This book sold me since Flashback Flashback allows a former primary database to be reinstated after a failover with ongoing restoration operation (provided that enough newspaper flashback is available)

  My own experience is I tried a test failover without it and trash my primary test.

  I did a test of simple failover a few weeks ago, here are my notes.
