T500: Switchable graphics on Windows 7 RC 32-bit?

Hi, I've got a new T500 2055-CTO with switchable graphics. Has anyone gotten this to work? Whenever I try to switch to ATI nothing happens (the mouse cursor goes into busy state for a few seconds the first time I try after a reboot).
Besides, my screen image gets corrupted periodically while working using the integrated Intel graphics, I can fix it by rearranging windows etc but quite annoying.
Also, my mouse when controlled by the trackpoint/pad will freeze up every now and then but keyboard will still work when this happens. No issues with an external USB mouse attached.
I've tried the official switchable Vista 32-bit driver and also a beta one listed here: http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-71851
But none of them solve the problem.
Any ideas or input would be appreciated.
Thanks,
Hans

Hello Hans:
I have a W500, which I think is somewhat similar to a T500 - it also has switchable graphics.
Long, long ago (back when I was using Vista before SP2), I went into the BIOS and turned off the switchable graphics feature - I told the computer to use the discrete graphics all the time, and to totally ignore the integrated graphics.
Since then, my life has been a lot simpler, the computer has been trouble-free (both on Vista SP1, Vista SP2, and W7 build 7100), and battery life has been more than sufficient for my needs (about 3 hours total, with everything set to 'high performance').
I think that the 'switchable graphics' feature is one of these things that sounds good conceptually, but is too much of a PITA in reality. I applaud Lenovo for trying it out - but, unless you really, really need it (meaning, you suffer from electricity shortages on a regular basis), it is more trouble than it is worth. Just turn it off, forget about it, and start enjoying life.

Disabling switchable graphics for windows 7

Hi experts,
I am using a 4gb T400 and I am trying to free up the memory by disabling the switchable graphics in the bios change it to discrete graphics. and yet I still cant get close to a 3gb memory on my 32 bit Windows 7. I have seen in this forum they have done it but I cant seems able to get mine close to that. Is there anything else I can do !?
I have reboot a few times between integrated graphics and descrete graphics, to try to free the memory but to no avail. Pls any1, is there anything I have missed out.
Solved!
Go to Solution.

boot into BIOS with F1
Enter Config->Display->
Switch OS detection to Disable.
boot into OS
uninstall Switchable graphics driver from unitl and install ATI driver from ->

How can enable switchable graphics in Windows 8.1 (Bootcamp)

So I just dropped $3,000 on a high end (late 2013) 15" rMBP and immediately installed Windows 8, and then 8.1, through Bootcamp. I need Windows for a lot of engineering programs, as well as occasional gaming. I bought a MacBook because I prefer OSX for programming - I love Ubuntu, but my previous laptop had driver issues (ironically enough, also due to the graphics card) that would cause it to overheat and only give me about 45 minutes of battery life.
After using it for a little, I realized that the MacBook was VERY hot. I closed all of the power intensive applications and proceeded to browse reddit on low brightness and power saving settings to let it cool down, but it did not cool down much. I shut it down, and turned it on about 15 minutes later, when it had successfully cooled down. I realized that just being booted into Windows caused the laptop to get unreasonably warm - I'm assuming that it's because I have the Nvidia GeForce GT 750M graphics card in it. I can not seem to find an option to enable power saving graphics.
Is there any way to use the integrated Intel graphics rather than the discrete card? Not being able to run Windows reasonably well would really make me regret this purchase, especially when I could have bought a different laptop for much less and installed a Linux distro on it.
Any help is appreciated.

Sorry, but I think the above post is bad advice. It's unlikely to be a fan issue as these are generally controlled by firmware. If your laptop is getting very hot in Windows with only minimal and light use then that suggests a power management issue.
The first thing you'll want to do is check that your Power Management settings are not set to "High Performance". A lot of people select this option thinking it gives them the most out of their computer and hardware purchase without realising what it does and that it comes with significant issues and tradeoffs.
What the High Performance setting does is disable CPU throttling, forcing the CPU to run at its maximum speed constantly (on all cores) and draw its maximum power load, even when not required. This causes the laptop to heat up very hot very quickly even if you aren't doing much, while simultaneously killing battery life. If you found a way to replicate this behaviour in OS X (and turn graphics switching off) you'd find the laptop would get equally hot and fans would ramp up to maximum speed just to try to keep things cool. If you hear your fans spinning at maximum then that is evidence that fan control is working.
It's a very unnatural behaviour and there are almost no situations where you ever need to use it. Microsoft should really make an effort to hide it and make it harder to access. High performance sounds nice and "Why wouldn't I want my laptop to run with high performance" is what most people think. Of course, Microsoft isn't very good at understanding what people think.
For most purposes "Balanced" is the Power management setting you'll want to use and this more closely reflects what Apple uses in OS X. Failing this, it could be that whatever software you're using is very badly coded for power management, but this is less likely and unlikely to cause the severe heating issue you described.
Finally, there's no need to regret your purchase. It's an amazing laptop and the best way to run Windows in my opinion. The only thing missing I can think of is switchable graphics driver support but this isn't anywhere near as severe a problem as what you've described.

T400, Switchtable graphics problem, windows 7 64 bit

Hello everybody.
I buy a new T400 with switchtable graphics. I install a clean windows 7 64 bit professional version. I install system update and check the required apps and drivers. Everything is done, but after the reboot, I switch to intel graphic card and the screen is bouncing really hard. I switch back to ati evetrything is ok. I check if is use a lower resolution or lower refreshing rate the intel is working well. What is the problem? At the device manager everything looks like good.

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.

T500 Recovery disk for Windows 7 64 bit

I have received Recovery diskWindow 7,64 bit and they do not appear to be valid.
Does anyone have the same recovery disk? If yes, do you have three files in theWindows 7 statup menu after installing the recovery disks?

Hi,
please apologize, but I'm a bit lost.
In you first post you noticed following: "I have received Recovery diskWindow 7,64 bit and they do not appear to be valid."
I thought, that you have some issue with the maing Disks?
Please correct me if I'm wrong.
Please note, that the Recovery CD/DVDs are made for multiple systems with multiple configuration. The correct installation of the correct drivers is accomplished due to multiple scripts, that are executed, which detects your system configuraiton and according to their output, the appropriate drivers will get installed.
I wanted to remark this as, there might be some differences in the installation of two systems, when they have other configuration.
Please feel free to correct me if I missed some point.

OpenGL3.3+ Update? Edit: Radeon HD6490M switchable graphics driver update Windows 7?

So I recently purchased a game that requires me to run OpenGL3.3 or more. Currently I can do OpenGL3.1, and after poking around some I see no reason why my graphics cards couldn't support it. Do I need to download something for OpenGL, or do my drivers need to be updated? (HP Support says they don't but I'm skeptical). Any help/advice is appreciated. Also, I was poking around this old question, but couldn't do squat with it... quite new at all this after all... Edit: I've been looking more, and it seems that the answer would be an updated graphics driver. The problem is, I'm not sure if there is one (Again, HP Support, etc. says I don't need one...). I have a dv6t-6100, with Radeon HD 6490M switchable graphics on Windows 7, 64-bit. It sounds like others have had luck updating their drivers just by the virtue of running on Windows 8 rather than 7. Any suggestions, work-arounds, other drivers that might similarly work for me?

So after updating to Windows 10, what I was trying to do originally works now that my video drivers have finally updated. Doesn't solve the original problem exactly, and I continue to wonder why HP kept me in the dark on these updates...

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.

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.

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.

T500 integrated graphics in W8.1

I have a T500 (2081-CTO) with switchable graphics (Intel GMA 4500MHD and ATI 3650) and a 1680x1050 internal display. I am thinking about an upgrade from Vista SP2 to either Win7 or Win8.1. I understand from this thread - http://forums.lenovo.com/t5/Windows-8-and-8-1/T400-Switchable-Graphics-and-Windows-8/td-p/840491 - that switchable graphics may be made to work in Win8.1. My first question is, if I do a clean full install of Win8.1 and then get Intel's 8.15.10.2702 from MSDN.Microsoft.com Windows Update / Dynamic Update, what will I have? Will I have full internal resolution, or something less? My second question is, should I set BIOS for "integrated only" before doing this? Thanks.

Hi! I'm in the same situation as you. Actually, I haven't found any solution for switchable graphics yet, but I can tell you, Win 8.1 is great and you should switch to it. Startisback is great also.
Except switchable graphics there is no other cons. ATI or Intel work great on WDDM drivers from Windows Update (you don't need to search for branded drivers). Your Win may switch your video cards randomly (mine used to), so I turned off switchable graphics in BIOS, and set ATI as the only video card. For month I have no problem at all, my T500 uptimes are for around 2 weeks.

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.

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.

W7/64-bit on W500 - Switchable Graphics problem

Hi,
Did a clean install Windows 7 Ultimate (64-bit) on my Thinkpad W500 (4062-3CG).
Having problem with "ThinkPad Switchable Graphics Driver for Windows 7".
ATI driver won't load, so default Intel chipset is used with poor graphics as a result.
I have also tried "Windows 7 BETA Drivers and Utilities" with no luck.
Yesterday the graphics worked for a short period of time, that was after remoting my Thinkpad with RDP? very strange. But after reboot graphics was back to non functional again.
Any ideas?
TIA
Johan

Did you apply Lenovo driver packages in any specific order? Don't really understand what I missed?
My plan was to do a "clean" W7/64 install and after that run ThinkVantage System Update 4.0 for latest drivers.
In my case ThinkVantage System Update 4.0 could not start without Access Help for Windows 7 installed, that was the first dependency problem.
However, after that ThinkVantage System Update 4.0 run successfully and everything works fine but the ThinkPad Switchable Graphics Driver for Windows 7.
The ThinkVantage System Update 4.0 applied latest updates for everything including the BIOS. When I try to run BIOS update separately for getting around the graphics problem it says BIOS version is OK and no update needed.
Tried to disable Switchable Graphics in BIOS-setup using Discrete but that does not fix my problem?
