Windows 7 RTM x64 Power Manager and switchable graphics not working

Installed Windows 7 RTM x64 on my T400. After windows update and installing Lenovo's drivers, everything is accounted for. ATI graphics works fine, and I can see the Intel graphics on the shortcut menu. I just cannot manually switch to the built-in graphics, nor did I see the Power Manager. What do I need to do? I have installed the drivers for the power management, even though on the list of driver on lenovo's webpage it says it's only for SL models.
Help would be appreciated.
Specs:
T400
LED
ATI/Intel switchable graphics
4Gb

Have you installed the Power manager http://www-307.ibm.com/pc/support/site.wss/WIN7-BE​TA.html#powm ?
And after that, make sure you have installed the right driver (the one for switchable graphics): http://www-307.ibm.com/pc/support/site.wss/WIN7-BE​TA.html#m8xswitch
Hope that helps.
I also have Windows 7 Professional x64 on my T400 and everything works fine (i only uses programs and driver from here: http://www-307.ibm.com/pc/support/site.wss/WIN7-BE​TA.html

  • Windows error: iTunes crashes (uninstall and reinstall does not work)

    Hello all.
    I (and another user) have had a problem with iTunes crashing when trying to open it. Windows just generates the typical vague error message that explains nothing as to what the problem is. Uninstalling and reinstalling did not work, and using the "Repair" option did not work either.
    This was the solution. Hope it works for you. Cheers.
    C ;o)
    Here are the steps, some might be redundant, but still follow them to try and get iTunes to work.
    1. *Extremely important* Close the QuickTime launcher in the tray on the right side of your Windows TaskBar (right-click on the blue QuickTime "Q" logo next to where you have the time and date and select "exit".) The QuickTime logo should disappear from the tray.
    2. Go to where your iTunes library folder is, copy it and put it elsewhere on yoour hard-drive. This is where you asked your iTunes to point to and keeps the full repository of the files sync'ed to your iPod. If you don't do this, you will have to re-create the full library of all the music and files you have put into iTunes.
    3. Unistall iTunes and reboot your PC.
    4. Go to c:\Program Files\Quicktime and delete this whole folder.
    5. Go to c:\Windows\System 32 and: delete the Quicktime FOLDER there; then (ii) scroll down and delete all other QuickTime related files (there should be 5-10 of them, I didn't count, some will have a name like QuickTMvr whatever).
    6. Empty Recycle Bin.
    7. Reboot your PC.
    8. Go back to Apple Website and download: iTunes, and (ii) QuickTime installation only (without iTunes).
    9. Install QuickTime FIRST (use newly downloaded version)! Check it works OK by opening it.
    10. Close QuickTime lanucher from tray, as explained above in step 1.
    11. Install iTunes (use the newly downloaded version).
    12. Open iTunes. If it opens fine (clap your hands and say "hurray", and actually I said out loud to my PC, "Please work" and it did - I don't know if this step helped at all. ;o) ), then close iTunes FIRST BEFORE DOING THE NEXT STEP. Go to where the new iTunes (and library) folder is, rename the new iTunes folder (as you might notice when/if you open iTunes, that it is all blank), and copy the old iTunes folder (from step 2) to the same location. Re-open iTunes. It should be the way it opened the last time.

    Btw.
    Don't forget that, from my experience, most iTunes errors comes from malfunctioning instances of QuickTime.

  • Switchable graphics not working on windows 10

    Model: HP Pavilion dm4-1024TXI currently upgraded my Operating System from Windows 7 to Windows 10. I have issues with switchable graphics. Iam not able to use My graphics card(ATI Mobility Radeon HD 5000 Series). Updated driver using windows update and even tried updating from ADM website, Still doesn't work. Right now iam unable to use any graphics intensive applications.      Will HP provide Switchable Graphics Driver  Windows 10 update for my laptop model?Is there any fix for this issuse?Or should i Revert Back to Windows 7

    Hi, I had the same problem on my HP laptop and finally figured out a solution.  1. I downloaded the Windows 7 version of the drivers from the HP website (make sure it's the hp version not the generic amd driver). 2. Uninstalled the drivers that were installed. Type in Device Manager, select Update Devices then display adapters, right click and uninstall both devices.3. Reboot4. Install the intel driver in Windows 7 compatibility mode5. Unzip the AMD exe file using 7zip 6. Go into Device Manager again, right click on the AMD graphics adapter, Update Driver software, Browse computer, Let me pick, Have disk. Browse to the AMD folder and find the INF file that works.7. Reboot Now I can use an external monitor. Catalyst control panel doesn't work, but I can do what I need to do.  

  • AMD CCC / switchable graphics not working properly

    Hi all,
    ok first of all i read bunch of posts on this forums, and on most of them i saw only responds with links and to download and update drivers - and those things seems not to work for most of people. So i decided to write here a post where someone will actually fix this problem because it is common on most of HP laptops.
    First of all, i bought my laptop in Qatar while i was on bussiness there.
    Model: Pavilion dv6-6b20se
    Product Number: A6N20EA#ABV
    Graphics: Intel HD 3000 and AMD HD 6490
    I bought this computer because im working as an architect and designer and sometimes i need it for rendering, and yea i would like to mention that part time i love to play games. So at that time (2 years ago) and for that money it was pretty decent laptop.
    So i've never touched anything myself on laptop, i always let my HP Support Assisstant do the work it is on computer. To be honest i didnt even know that this option of Switchable graphics exist. Until yesterday when i put game to play and i got problem wherever i press ESC it closes came and it crashes.
    I googled around and I saw that the problem apears when your graphic card is low.
    Requirements for the game:
    Minimum System Requirements
    MinimumOS: Windows XP SP3 / Windows Vista SP1 / Windows 7
    Processor: 1.8 GHz Intel Core 2 Duo or equivalent AMD CPU
    Memory: 1 GB RAM for Windows XP / 2 GB RAM for Windows Vista and Windows 7
    Graphics: 256 MB (With Pixel Shader 3.0 support)
    DirectX: DirectX 9.0 c compatible
    Hard Drive: 15 GB
    Sound: DirectX 9.0c compatible
    Supported Chipsets: NVIDIA GeForce 6800 or greater, ATI Radeon X1600 Pro or greater.
    Please note that NVIDIA GeForce 7300, 8100, 8200, 8300, 8400, and 9300; ATI Radeon HD3200 and HD 4350 are below minimum system requirements. Updates to the video and sound card drivers may also be required.
    Recommended System Requirements
    OS: Windows XP SP3 / Windows Vista SP1 / Windows 7
    Processor: 2.6+ GHz Intel Core 2 Duo or equivalent AMD CPU
    Memory: 2 GB RAM
    Graphics: ATI Radeon HD 2900 XT, NVIDIA GeForce 8800 GT, or better
    DirectX: DirectX 9.0c August 2008 (included)
    Hard Drive: 15 GB
    Sound: DirectX 9.0c compatible
    So by looks of specs here and specs of my computer and the game is like 4 years old, it should fly on my computer.
    I googled a bit more and i saw that every program reads only Intel HD graphic card and not AMD. Ok so i went and checked tutorilas on youtube how to switch it and there is where my suprise was. When i open CCC as per everyone on internet i dont have Switchable Graphic option - only Power Play. So i read on your website that some computers need to be set in BIOS from Dynamic which was my original setting to FIXED. I did that to but my option when i right click on desktop for switchable graphics disaper and my CCC is not working.
    Ok so i went to your website again, was looking for original drivers for my computer. And there are 3 drivers.
    1.AMD High-Definition Graphics Driver
    2.AMD/Intel Switchable High-Definition (HD) Graphics Driver
    3.Intel High-Definition (HD) Graphics Driver
    Ok so when i download them, i can install only No.1, other two i get message that i dont have minimum requirements.
    so i checked those to, and it says that  you need to have windows 7 which i have since i got this laptop with original licensed product.
    The thing is when i install new version of AMD driver and CCC i get switchable graphics option when i right-click on desktop, but when i get in in CCC i get defoult page and there is no option to switch. When i update intel graphics i loose switching. Either way, it wont work, and im stuck with crappy card that i cant use on bunch of programs and games that i need it for.
    So please for once give us a bit detailed answer on how we can fix this. Because it is not only me that have this problem, alot of people are having them and they still cant fix this.
    Sorry for my lenghty post, but i thought i needed to explain in more debth.
    Thanks in front for reading and takning time to answer.

    And yea i forgot one thing. When ever i instal newer version of AMD driver in Device manager it changes from AMD HD 6490M to AMD HD 7400M Series. Dont know why it constatnly does that.

  • Installed Windows & 32 Bit But Drivers and USB ports NOT WORKING.

    I bugh an HP Pavillion TS 14 Notebook that came preinstall with Windows 8.1 64 bit which I hate so wiped the drives and installed Windows 7 32 bit and now I have a big problem.  None of my network drivers work and the 2 uSB ports where I plug my mouse and other SB hardware in no longer work. 
    I did a back up of the SW Set up file that has all of the HP dvers for my laptop but both the network and video divers won't install. And When I try to install the drives I get the eror message saying they are not compatible with this version of Windows.
    I have loked on the HP website under my laptop model which s as above but HP don't do drivers for Windows 7 32 for my laptop. And I have looked on both the Realteck website for both the Realteck ethnet and Realteck wireless network drivers but none of them work or install on my operating system. The video drivers Intel don't work either. So I am really stuck a I cannot go back to Windows 8.1 as though that 32 bit Windows 7 would work on my laptop but most of my drivers are not compatible with the operating sytem And I don't want to install 64 bit Windows as I like 32 bit.
    The drivers that are not working on Windows 7 32 bit are:
    Realteck RTL8188EE 802-11b/gn witeless lan
    Realteck ethnet die and
    Intel High definition graphcs driver 
    Which don't work at all on Windows 7 32 bit as they are 64 bit only drivers.
    So can you please post me a link bth the network and Intel graphics drvers that work with my laptop. As I have tried lots of different Realteck and raphics drivers for Window 7 but NONE of them work on my system. And None of my USB ports are working either. So how do I solve this problem?
    This question was solved.

    Hi:
    Should be no problem to get W7 32 bit to work on that model.
    Just use all of the drivers and software from the HP Probook 450 G0 on your model except the Audio, BIOS and firmware files.
    Your model uses the Intel HD graphics driver only.
    The first driver you have to install is the Intel chipset installation utility and then reboot.

    Audio:  Accept the agreement.  Download and install the first driver on the list.

    If for some reason, the Intel HD graphics driver from that model does not work, then use this one...

  • HP 15-g505nc (K7R17EA) - Switchable Graphics not working

    Hello,
    I have a problem with my switchable laptop graphics (A4-6210 APU with R3 / HD 8570). When I try to run some games or more demanding application with high performance settings, applications are using only APU integrated graphics, but not dedicated. Even in game setting dedicated GPU is recognized, but the option is greyed out. I've tried to install both latest AMD Omega drivers (14.501.1003.0) and also HP provided drivers for my model (13.351.1105.1005) with no success. Also in BIOS there is no option to cofigure swtichable graphics.
    Please, need some help. I'm pretty new HP and AMD user. I was used to intel/nvidia hardware, so maybe I am overseeing something. Thanks.

    Hi @LukasB92 ,
    Welcome to the HP Support Forums. I see that you are having some problems with the switchable graphics options. I will be happy to show you how to use the dedicated card. You will actually use the Catalyst Control Center to determine which program uses which graphics card. This HP document on switchable graphics Figure 1 will show you how to use the Catalyst Control Center. Make sure that you are using this HP AMD High-Definition Graphics Driver.

  • New power adapter and battery, still not working?!

    A couple days ago, my macbook stopped charging. The power adapter was plugged in, but there was no indication that it recognized it or was charging, so I figured it was a broken power adapter. I bought a new one, plugged it in, everything was fine - until the next day. The new power adapter stopped working as well. So, I go to the genius bar, and they tell me it's my battery. I buy a new battery and plug in the new charger. Everything's working again, until I unplug the power adapter to move my laptop into another room - and now it's not charging again! I tried every power outlet, and something is definitely wrong with the macbook itself. I'm pretty frustrated since I've now spent $200 on new stuff and the problem still isn't resolved.
    Does anyone have any ideas?

    A, I love Alexia Potatoes--I think I'm having some garlic mashed with dinner tonight.
    B, Have you downloaded and applied this firmware update?

  • Power Outage and Now Ethernet Not Working and When Imac Goes to sleep...

    Last I had a power outage, now my ethernet connection does not work, I have switched cable powered everything off and back on, still nothing. Also since the outage when my MAC goes to sleep it does wake back up. Any Ideas?????

    Russ,
    Try booting up from the Tiger install disc (put disc in, restart, hold C key down as soon as you hear chime, release C when you see the spinning gear). Then select your languag, go to Disk Utility, select your startup disk and choose Repair Disk. Then quit installer and reboot normally.
    Then when booted normally, do to Disk Utility, select your startup disk and Repair Permissions. Post back.
    It is not good for a computer to experience a power outage while booted up. Various things can get messed up. After you get straightened out, I would strongly suggest getting an uninterruptible power supple (UPS or battery backup). I use one made by APC and think they are a very important accessory to have.
    Regards,

  • Anyone know the syntax for printing-to-file for the file name in windows? Tried the following and it did not work...C:\Documents and Settings\Cal\My Documents\FolderForPrinting but I also put it in small quotes.

    Two issues I think.
    One is how a file is specified to print to.
    Second is how directories with spaces are allowed, and the detail for allowing spaces in directory or file names.
    This is an XP operating system from Windows.
    Firefox is the browser.
