Noob Question: T400 Switchable Graphics?

Just got my T400 this weekend, and I have a question about the switchable graphics feature.
I can't actually find any way to control the switchable graphics. I see the different battery life options and that type of thing, but is there anything that actually says SWITCHABLE GRAPHICS?
I was looking in the Power Manager app but found nothing.
I did go into the BIOS at startup and verified that I do have this option.
Can anyone help a noob out?

T400 switchable graphic problem

Dear Jhem,
The model of T400 I have is 2768-AA6.
I have some questions on the switchable graphic card function:
1.Under device manager are we suppose to see two GPU installed or just the active one? I can only see the active one. But most ppl around me who have T400 can see both two GPU. Is there anything wrong with my machine?
2. The automatic hot switchable function is not available at all. I remember the switchable function is that when we use battery the computer can choose integrated graphic card while when we use AC adaptor the computer can switch to discrete graphic automatically. However, no mater what power source I use to power up the computer, the integrated graphic card is selected. The only way I can use ATI graphic card is get into BIOS----->disable switchable function------->select discrete graphic card and then restart computer.
Are these common problem for T400? They make me very unhappy as the most attractive function of this model cannot be use at all.
Thanks a lot!

Anyone can help?
Thanks!

G50-45 Switchable Graphics

Hello,
I have a question regarding switchable graphics in this laptop. Are these two cards runing simultainously so there isn't really any switch where you can decide which card do you want to use right now? I had laptop with this future before and it had a program running in the background where you choose if you want to use integrated graphics or dedicated one. I only have some AMD software where you can set which aplications should use high performance or energy efficient settings. When I fe. run some game, there isn't anything that would tell me that I'm using dedicated card. I installed AMD System Monitor which tells me APU resource distrbution is 100% from CPU although GPU does seem to do something.
Is this how my laptop should behave?
I have Windows 8 32-bit.
Amd Radeon R5 230 and Radeon R4 driver no. 13.302.1601.1001

So to answer my own question. No, my dedicated graphics card isn't working. I just tried new LOTR game where it let you choose which graphics card you want to use, and it only shows the R4 card, not the dedicated M230 one. So, what should I do? I have clean install of Windows 8.1 64bit with newest drivers from Lenovo site.

Bug on t400's fn+brightness? (after install switchable graphics)

it is great that we can use switchable graphics on windows 7 now, thanks.
well, i found a bug (not only my t400, but also several of my friends'), the FN+brightness problem.
1. AMD graphics
2. switch to INTEL graphics (fn+brightness function is just OK)
3. switch back to AMD graphics (fn+brightness is down,,,,) (fn+f5 f8 etc. are OK) (fn+pgup (light) is also OK)
A. log off --> log in (no use)
B1. restart (fine again)
B2. reinstall the hotkey features driver (include restart,,, ) (of course fine again)
C. switch to intel, switch back to amd, down again,,,,,,
is it a universal bug or there is something wrong with my system functions( settings, drivers etc.)
thanks a lot

Another possible work around: after resuming from sleep, toggle to discrete graphics and back to integrated. See if that sorts it until the next sleep - and let us know, please.

Updated Drivers / Proper OpenGL Support for T400/T500 Models with Switchable Graphics

Dear Lenovo, Dear interested users,
when will an updated switchable graphics driver for Windows Vista (and also Win7, they are both quite outdated) finally be available? The drivers are completely outdated!
With the current driver for Windows Vista (Version 8.563.2.1-090401a-079160C) only a fraction of OpenGL extensions are supported:
The internal Intel GMA 4500MHD can only Handle OpenGL 1.1 (instead of OpenGL 2.1 it is certified for). Therefore most applications needing OpenGL won't run.
The dedicated ATI Radeon 3470 only supports OpenGL 2.1 (instead of OpenGL 3.1 it is certified for).
You can verify this behavior with the utility "OpenGL Extensions Viewer".
I hope Lenovo didn't close the chapter switchable graphics for T400/T500 systems. It would be a shame for a company claiming to be a leader in business computing to deliver such poor driver-support.
In hopeful expectance of updated drivers,
Patrick

I'm having the same problems. Is anyone reading this?

Z68A-GD80-G3 - installing radeon 6990 graphics card - noob question

all, apologies for the noob question, but: how exactly do i install a radeon 6990 graphics card?
i have a Enermax ERV1250EGT power supply. the card is in the top blue pcie slot. i have connected the PCI-E 2.0 6+2 (8)Pin connectors (see http://www.enermax.co.uk/revolution85 - connectors tab, sorry no direct link but they are the red ones to be seen in the the bottom left corner of the picture: http://www.hardwareheaven.com/reviewimages/enermax_revolution_1250w/thumbs/10.jpg, i.e. 6 pin + 2 pin = 8 pin).
the card will just not start, i.e. when i boot the pc nothing happens. it works fine without and works fine with my old graphics card (gtx 260).
pics of the asus radeon 6990 here:
http://www.techpowerup.com/reviews/ASUS/Radeon_HD_6990/images/power.jpg
any ideas? is there anything different to this card than with other cards? have installed systems over the past 10 years and never had an issue until now.

S540 Switchable Graphics question

Hi.
Is here someone who has installed win 8 or 8.1 on your own and has working switchable graphic on lenovo thinkpad S540?
If yes what drivers have you installed ?
Or can someone help me with switchable graphics problem ?
I have installed all drivers from lenovo support and switching of graphics doesn't work.
Thanks
Jan

Hi, here is my solution for S440 - its are very simular computers:
try reinstall drivers from Lenovo site to your computer and Windows 8.1: http://support.lenovo.com/en_US/downloads/default.page#
You can use Lenovo Upgrade Ulity.
1) I installed driver for Intel HD graphics from Lenovo website version 10.18.10.3316 (it is old driver but modify for S540)
2) Then I installed AMD Catalyst Controller Center 13.9 from Lenovo website version 13.152.1.1400
3) And then you can't install optional actualization from Windows Upgrade called "AMD Graphics Adapter WDDM1.3" - it change graphics version!
Then everything is OK. No sleeping problem, brightness control and mainly Catalyst Controller is working good.
But only with this combination of drivers! (I tried some other new drivers but unsuccesfully)
I hope it will help you to solve all problems.

Power Manager 3.48 no longer has switchable graphics option

I ran Active Update yesterday and the Power Manager is now upgraded to version 3.48. It appears that there is no longer an option to switch between high performance and energy saving graphics. How is the graphics mode supposed to be switched now that this menu option has been removed from the right mouse button menu on the Power manager? Do I need to downgrade to a previous version?
In case it matters, I'm running a W500 with Windows 7 Professional 64-bit.
Thanks,
Danny

@ersiles,
I have the T400 with switchable, I just updated it to PM 3.64 and it does swtich. What I notice earlier when I wasn't able to switch the graphic was due to BIOS settings.
Check BIOS settings if you have it on switchable graphic mode and check if BIOS detect is enabled.
Once that is done, boot into Windows, uninstall all the video drivers, reboot. then install the drivers again.
Windows would try to install their version of the driver, click "Reboot later" when Windows prompt a reboot. Reboot only when ATi manager prompt the reboot.
I was having issue too on the T400 not being able to switch. It definitely helped me ..
Let me know.

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:

Have you installed the Power manager http://www-307.ibm.com/pc/support/site.wss/WIN7-BETA.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-BETA.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-BETA.html

Windows 8 Consumer Preview: AMD Switchable Graphics - Unswitchable

Hello everyone,
I have a HP Pavillion dv6-6004tx notebook computer, and I recently upgraded it to the Windows 8 Consumer Preview (Build 8250). I would like some troubleshooting from those who have/are experiencing this and may have found a way around it.
As far as the specs of my computer goes:
Intel Core i7-2720QM
6 GB DDR3 RAM
64-Bit OS
AMD Radeon HD 6700M
Intel Graphics Family
The problem lies within my display drivers. Some of you may also have a Switchable Graphics feature installed in your computers. But for those who don't, basically what it is is a feature that allows one to switch their display adaptor from a Power-Saving GPU to a High-Performance GPU, and vice versa.
In my case, as you can see above, the High-Performance GPU is the Radeon 6700M, while the Power-saving GPU is the integrated Intel one. My problem deals with not being able to switch back and forth between them, like I was able to back on Windows 7. As this is a feature of AMD Catalyst Control Center, I have searched their website and they actually have a supported driver version for Windows 8 CP, albeit it still being a beta and sometimes glitchy.
http://support.amd.com/us/kbarticles/Pages/Windows8ConsumerPreviewDrivers.aspx
(As you can see, my model: AMD Radeon HD 6000M Series is listed)
After installing the Control Center, I restarted and a pop-up notifcation tells me that:
"The Catalyst Control Center is not supported by the driver version of your enabled graphics adapter. Please update your AMD graphics driver, or enable your AMD adapter using the Displays Manager."
I found this odd at first, as my model clearly was listed. But after some inferencing, I realized that my computer must be running on the integrated Intel graphics by default. This was further reinforced when I tried playing some games and other applications (It would be slightly choppy - as experienced before when I had forgotten to switch back onto High-Performance GPU).
The AMD Radeon card used to have an error (The device won't start. Code: 10) under device manager, but with a fresh install of the driver obtained from AMD, it seems to be working fine. However, my computer is still using the Intel card by default, and I have no way of switching to the other GPU as Catalyst will not start.
Has anyone found a way around this?
This question was solved.
View Solution.

I'll give you a two way to make it work!!!! There is so much incompatibilities with the FIRST METHOD listed, you won't get use a Intel (less power consuming card) GPU to work after the changes! you've got to wait till HP let's it work properly or deal with power hungry AMD GPU even in battery mode .
THE SECOND METHOD listed works without any problem with compatibility in any apps BUT IT IS Require pace and order ( may be exhaustive for newbie's, no worries listed below got all the info you need to make it work)
SO the first option:
NOTE:THIS WILL TRIGER THE OUTCONTROL EVENTS SO PRECAUTION METHODS I WILL ADVISE FURTHER AS WE GO STEP BY STEP _ DOWNLOAD CHROME IF YOU RUNNING INTERNET EXPLORER ( GRAPHIC CARD WILL WORK WITH GAMES BUT NOT WITH METRO APPS THEY WILL NOT CRASH JUST NOT LAUNCH
ALL THE METHODS BELOW TESTED BY MYSELF AND GET WORKED YET MANY INCOMPATIBILIES STILL WILL REMAIN USE IT ON YOUR OWN RISK!
as i can tell all the games working properly yet battlefield 3 won't launch
1. AT first make sure that windows UPDATE IS SWITCH OFF or let you choose to download and instal (not automaticly or it will update ur device (at device manager) without ur permision and all eforts are gone!
2.uninstall AMD Catalyst from "program and components" at control panel, then uninstal all the devices Intel and AMD at device manager at the control panel (check unistal driver at intel HD driver)
3.reboot! after reboot download this http://www2.ati.com/drivers/hotfix/win8/amd_catalyst_win8_consumer_preview_[rc10].exe
and this
ftp://ftp.hp.com/pub/softpaq/sp53001-53500/sp53025.exe - 300mb
4. instal sp53025.exe at windows 7 compatibility mode (it'll unpack by default in C:/SWsetup)
then start the istalation make sure u choose a "custom" , THIS IS CRUCIAL - uncheck the CATALYST (check all the rest intell driver amd driver ect.) after the instalation do not reboot
5. Next start the instalation of the windows 8 consumer preview driver from AMD.
uncheck all the rest ( after the sp53025 there will be only AMD driver (check/uncheck) and the catalyst (check/uncheck) box available) uncheck the AMD driver and install only the CATALYST driver!!!!
Reboot! Enjoy !!! There will be no CATALYST(only the intel preference and settings where the CATALYST should've be) at the right mouse click but switchable graphic is now awailable LIKE THIS
Unfortunately you'll won't be available to choose between the INTEL and AMD ! AMD is now working by default
All the .exe will now recognize 6770m
AND METRO APPS WON"T WORK!!!!!!! AS internet explorer will crash as you'll open it
SECOND METHOD IF THE FIRST FAILS (WHICH IS IMPOSSIBLE IF HANDS ARE STRAIGHT MORE OR LESS)
FURTHER IS TESTED!
THIS METHOD EXCLUDE THE METRO APPS CRASH AND ALL THE REST INCOMPATIBILITIES WITH EVERY EXECUTABLE PROGRAMS AND GAMES!!!!
Note: Requires knowledge to sign your own drivers, disable signing enforcement at boot and modding some inf files.
I am not responsible for any damage that may arise. This guide is not exhaustive.
Requirements:
.NET Framework 3.5 -- Can be enabled within Windows 8, in "Turn Windows features on or off"
Windows Driver Kit (WDK) -- Can be downloaded from here
Configure Windows Update to only "Download updates but let me choose wether to install them", and hide both Intel and AMD updates. This is to prevent our driver be updated by Windows.
1.Download the latest switchable graphics drivers from this site: leshcat blog IT Tips & Tricks: Catalyst 12.3 Pre-WHQL UnifL for Switchable Graphics
2. Run the installer that will extract the contents of the file, by default it will ask you to disable "Signing enforcement of Windows", you will know that it is working after rebooting because a "Test Mode" watermark is added to the desktop, above "Windows 8 Consumer Preview".
3. At this moment, do not run the AMD installer yet. We need to modify some files. By default, the driver will be extracted to "C:\Drivers\Catalyst 12.3 Pre-WHQL UnifL".
4. Go to this directory, and open the following file "Packages\Drivers\Display\W76A_INF\C7133662.inf"
Do the following changes:
In the section [Version] add:
Code:
[Version]
CatalogFile=C7133662.CAT
There is a section that has the listing of all the supported cards. Rename it from "[ATI.Mfg.NTamd64.6.1]" to "[ATI.Mfg.NTamd64.6.2]"
It should look like this:
Code:
[Manufacturer]
%ATI% = ATI.Mfg, NTamd64.6.1, NTamd64.6.2
[ATI.Mfg.NTamd64.6.2]
"%AMD68F2.1%" = ati2mtag_VancouverC_PXAI, PCI\VEN_1002&DEV_68F2
"%AMD9519.1%" = ati2mtag_VancouverC_PXAI, PCI\VEN_1002&DEV_9519
5. Follow this guide to Test-Sign a Driver Package. (This guide is generic)
6. After the previous step, you should have a Catalog file and the inf file we modified previously.
7. Now proceed to run the AMD installer in "Win 7" Compatibility Mode. It is most likely that the driver install will fail at this stage, but the rest of Catalyst software will be installed.
8. Now install the driver using the "Have disk" method in device manager and your modified INF for both Intel and AMD cards.
9.If you did the test-signing process correctly, the installation will succeed for both cards.
10. Reboot and enjoy your switchable graphics under Win 8.
I still have to figure out how to make brightness controls to work.
BTW sorry for any grammar mistake, I am not a native English speaker.
Known issues:
- Sometimes switching may not work, resulting in BSOD.
- When AMD gpu is active, Intel driver context menu options are still available.
Features:
AMD gpu can be turned off, so battery will last longer.

Windows 7 64-bit: Switchable graphics and Ricoh card reader problem

Hi guys,
Two problems with my laptop. I'm using a T400, previously installed with Windows Vista Business 32-bit.
Switchable graphics worked well until I formatted and installed Windows 7 Pro 64-bit (I got the RTM through MSDNAA). Now, Windows can only detect either the discrete graphics or integrated graphics at one time. When the BIOS was set to switchable graphics and enabling the detection of switchable graphics on Windows, it could only detect the Intel integrated graphics. When I try to switch to High Performance graphics through the Lenovo power manager, the screen flashes once, and the ATi graphics card appears on the device manager with the code 10 error (cannot start device). Also, compared to this image, my power manager window that opens with left-click does not have battery stretch and switchable graphics options. I have to right-click to switch my graphics.
After some tinkering, I managed to activate the graphics card through the BIOS by switching it to discrete graphics only and disabling switchable graphics detection by Windows. Now the device manager shows the ATi card only, the Intel integrated graphics is gone. I understand that it should show both display adapters in the device driver when the ATi card is active: http://www-307.ibm.com/pc/support/site.wss/MIGR-70495.html#g4
The second problem is with the Ricoh card reader. I managed to install the drivers properly, but the device shows up with a code 12 error (This device cannot find enough free resources that it can use) in the device manager. That error appears on 6 items in the device manager:
Ricoh Memory Stick controller
Ricoh SD/MMC Host controller
Ricoh xD-Picture card controller
Ricoh 1394 OHCI Compliant host controller
Ricoh R/RL/5C476(II) or Compatible CardBus controller
SDA Standard Compliant SD host controller
Additionally, 6 error messages appear during every boot up, which I think is related to these 6 devices:
ERROR
Resource Conflict - PCI in slot 07
Bus:15, Device:00, Function: 00 (it ranges from function 00 to 05)
AND disabling the device through device manager results in a BSOD.
I've seen some people post about the Ricoh problem, but didn't have any resolution (at least for those who had the boot up error message too). The switchable graphics problem seems quite common too but in my case it seems like it is working fine EXCEPT for the fact that only one graphics adapter can appear on the device manager at one time and I can't do switching at all. Anyone know if I can somehow solve this? Sorry for the wall of text and two-problems-in-one. I put them together because I don't know if one problem is affecting the other as both problems appeared at around the same time.

As far as the graphics goes it's well accpeted the only way at present to switch is though the bios manually. There is currently no drivers that enable users to switch from within Win7. Know it's a pain but will just have to wait.

Windows 7 and switchable graphics stays in "Energy Saving" mode

I installed the latest switchable graphics drivers from Lenovo, and I can't switch to High Performance mode. It always uses my integrated graphics even when I try to select it from the power manager battery menu.
I tried updaing to power manager 3.25 and the latest bios, but still the same issue. anyone have any solutions?

try right clicking the batter icon>go to switchable graphics>high performance.

Switchable Graphics Mode in the BIOS is not listed(seen)

Hi everyone!
I've read that:
NOTE: If you do not see Switchable Graphics Mode in the BIOS or it cannot be selected, see the following section Updating the BIOS to enable Fixed Mode .
However, I didn't see that switachable craphics mode is seen in my BIOS:
Product Name: HP Pavilion dv6-6093ex
Product Number : LM610EA#A2N
Version of BIOS is: F.05.
Vendor of BIOS is: Insyde
Also, I would say that my BOIS is not a UEFI BIOS because I cannot navigate the menus with a mouse but only just with the keyboard.
However, I really was told that I shouldn't update the BIOS unless I am having a problem with it.
Thus, I am afraid that if I had updated it, I would be encountring some problems not loading my machine well. However, I really want to know how to switch to external or internal adapter, thus I read here:
http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c02948560#fixeddl

Please see OpenGL Applications Cannot Use Discrete GPU with Intel + AMD Switchable Graphics for the basic procedure to update the BIOS and change the BIOS setting.
