Radeon HD 6490m Switchable Graphics Problems

Hello.
My notebook has been really sluggish lately, especially when browsing the internet, gaming or photo editing. It started a few weeks ago... never had any problems before. I didn't install any new programs, updates or drivers, so I don't know what caused it.
I did a clean install of Windows 7-64bit last night and got all the drivers from HP support. It was still being sluggish, so I disabled hardware acceleration on Chrome and ie11 and that solved the problem on those two programs.. but the rest is still being slow (even the mouse pointer is lagging). So I'm thinking the problem has to do with the graphics card (?).It's a Radeon HD 6490m (switchable w/ Intel HD Graphics).
I have my power option set to High Performance and the switchable graphics set to High Performance GPU. Are there any other settings I could tweak? Or a compatible driver I could try?
Thanks

Hi @johnw80 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv7-6179us Entertainment Notebook and issues with performance lags. Thank you for all the information about what is happening and what you have done thus far. Something is slowing the Notebook down. Did you install some virus protection or a firewall? If you disable the virus software, are your speeds better.
Here is a document on improving your system.
Try seeing what is active in the task manager, ctrl +alt+ del see what is running.
If that does not help at the end of this document it shows you to do a hardware test. The final thing you should try is to reload the factory BIOS settings.
Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system at the time of purchase. It will make sure all your updates have been completed.
Please let me know.
Thanks.

I have a HP Pavilion dv7-4276nr Entertainment Notebook PC and the latest driver I can download from HP are from 2010!! Lots of games are not running properly because of the lack of updated drivers and I cannot download them from de ATI page since they wont work. Please tell me if there is any other place from where I can download a more updated driver. Thanks in advance.

@stormsfury
I understand that you are looking for help with disabling the more powerful GPU on your notebook.
I did some searching and found a few posts on this matter, by a few of the HP forum experts. Check through these pages:

Radeon HD 8750m switchable graphics driver BY HP is not working on Windows 8.1

Hello all,
I have laptop Envy 6-1200el.
It's a good machin but I have always been annoyed by video drivers trouble.
When I bought my PC last year it worked good when we had Windows 8, but the video drivers didn't work properly already there.
The drivers made troubles when I tryed to start some 3D applications as Batman: Arkham Asylum. The problem was the HP video driver. That driver is made by Radeon HD drivers plus Intel HD 4000 series all together.
To make the two video cards working together properly you cannot use intel driver installation first then the AMD catalyst installation utility, but you need a driver installation utility that installs the two video cards both, otherwise the switchable graphics will not work properly and 3D applications won't start.
When I had Windows 8.1 update I had absolutely to find a new driver. I downloaded the automatic utility from AMD site and luckily it downloaded an updated driver that was including and installing together both the video cards properly. Since there my laptop started to work very good in everithing.
Some days ago I had to format my PC and that good video driver got lost.
I installed almost everithing including windows 8.1 update but I sadly discovered that on AMD site it was downloadable only the Radeon HD driver not including any more switchable graphics installation and Intel HD driver.
I have now installed the video driver given by HP on the right laptop portal, but this driver IS SO BAD!!!
HP says that it's an update driver working properly on Windows 8.1 but it's false!
MY PC WITH THAT HP DRIVER IS MAKING MANY TROUBLES:
- 3D GAMES ARE NOT STARTING OR NOT WORKING PROPERLY;
- PASSING THE MOUSE ON THE NEW START BUTTON ON WINDOWS 8.1, THE BUTTON BECOMES BLACK!
- HP UTILITY CENTER IS NOT OPENING;
- HP SUPPORT ASSISTANT IS NOT WORKING PROPERLY;
- THE SYNAPTICS MOUSE DRIVER DOESN'T WORK PROPERLY, THE DOUBLE TOUCH DOESN'T WORK ETC.;
- iNTEL DRIVERS INCLUDED ON THAT HP PACKAGE ARE OLD;
- SWITCHABLE GRAPHICS DOESN'T WORK GOOD AND IS NOT ABLE TO ADDRESS SOME 3D CHARGES TO THE RIGHT CARD.
PLEASE HP RELEASE AN UPDATE! pLEASE MAKE A REAL COMPLETE DRIVER THAT IS REALLY ACTUAL AND IS REALLY WORKING ON WINDOWS 8.1 WITHOUT CONFLICTS, WITHOUT GRAPHICS ERRORS ETC.!!!
THIS SITUATION IS UNACCETTABLE, SOLVE IT PLEASE!

Hi Fotoji,
I want to be honest, it's very disappointing for me to be treated like a child.
You should know that most of the people you meet here in this forum are not n00bs and the causes you suggest to consider haveall already been excluded in every way you would try yourself too!
The fact you say, that the issues are caused by a 'broken OS' are so disappointing and unbelievable!
I work in IT field since I was 14yo and now I am a graduated 28 who knows very well how to handle a PC in a clean and smart way.
Look, many of these issues was already 'on' when I bought and started my PC for the very FIRST TIME.
The video drivers needed are auto-installing drivers containing intel and AMD video drivers both and installed together at the same time.
The first day I had my PC the system was VIRGIN, I simply installed steam then ran 'Batman:Arkham Asylum' to make a try, it has never ran up, no matter if the OS is W8 or W8.1, no matter if the PC is new or used for 6 months, that driver has never worked good.
I tryed many things, used HP recovery manager several times in order to make a clean OS new installation, but it always went like that.
Recently I sent my computer to HP Italy fro an hardisk problem, replaced in warranty. The laptop came back CLEAN, perfect, with W8.1 and all the new recent drivers.
The problem was the same, games did not run or ran badly, the start symbol was black, HP Utility Center didn't work.
So tell me where's the magic when I unistall in a CLEAN AND CORRECT way those video drivers, why EVERITHING COMES TO WORK SO GOOD BACK????
Some months ago I knew that those drivers where so bad so I tryed to download the original driver package from AMD site, hoping that they was including the intel video drivers both, and guess...IT WORKED!
Those drivers was including the intel video drivers too during installation, then after a restart I had NO GRAPHICS ERROR, NO HP UTILITY CENTER FREEZE, ANY GAME OR 3D APPLICATION WORKED AT LEAST 2x FASTER AND NOT ANY COMPATIBILITY PROBLEM IN ANY STATE OR SITUATION.
Unfortunately my laptop started to have maybe some motherboard power problems and my HDD passed away then HP took my pc and fixed it.
When it came back it was perfect again, virgin, with all the update installed, with those bad HP drivers installed again, so with all those problems that I found since I bought it: graphics error, compatibility problems, some programs freeze, all WHITOUT TOUCHING ANYTHING!!!
I knew that I would solve it just downloading the right drivers directly from AMD site but UNLUCKILY THE NEW CATALYST 14.4 DIDN'T INCLUDE THE INTEL VIDEO DRIVER ANY MORE.
I had all those compatibility, stability and graphics problems always with a just-formatted computer with all the updates installed, a virgin untouched machine just formatted completely automatically using HP recovery manager or fixed by your engeneers!!!
The only case everithing worked very good was when I used the original AMD's drivers, when these used to inclued the intel graphics drivers too during AUTO-INSTALLATION.
I am replying now using a just-formatted machine automatically and perfectly just using HPRECOVERY MANAGER,and updated using WINDOWS UPDATE and HP SUPPORT CENTER self updater.
So guess what???? When I uninstall in A CORRECT WAY your HP video drivers (doesn't matter if the new one or the oldest) everything works good back, and when I used original AMD drivers everything worked so good.
It's so hard to do something wrong about it, the driver installation utility are IDIOT-PROOF, you cannot do anything during installation except for clicking the RESTART button.
So AMD used to make perfect drivers and now not any more, sadly, every issue disappears without your driver installed, HP sent me a perfect virgin computer with the same issues.
So please, don't tell me that AMD is able to make better software, don't tell me HP is not able to handle a recovery and sent me a pc with the same issues, don't tell me I probably made a bad use of my VIRGIN laptop after years spent on SGI workstations UNIX based.
I know how to keep a pc clean, and I'm telling you something more: the new synaptics mousepad driver package you are giving from HP website and HP support center DOESN'T WORK GOOD TOO!!!
Once you accept the auto update it starts with the self installation, but after the restart gess what?? The double toe gesture used to simulate the right click doesn't work any more!!!
No matter if you try to change any option in the control panel, no matter if you have windows 8 or 8.1, just try to unistall that and reinstall the old synaptics mouse driver and, OH WOW MAGIC, IT WORKS GOOD BACK AGAIN!!!
So now what?
Are you thinking that HP engeneers who fixed my laptop wasn't able to re-install windows and drivers?
The IT engineers working for HP are maybe also n00bs that can't handle a pc format and send me a BROKEN OS as you said?
I am magically breaking my os system just clicking one time on clean automatic HP recovery button then click on the automatic update buttons twice????
Perhaps AMD is able to make more stable end recent drivers than HP does???
(considering that aven the last HP graphics drivers update is so bad because the intel side of the package is very old and you can recognize it just making a comparison with the new intel additional control panel!)
I don't need to recover the system for the 4th time in a proper way (plus HP fix would be the 5th!), I know these silly things.
I need to be taken seriously and not be treated like a grandmother who's not able to switch-on a smartphone!
I would challenge anyone to operate on my computer and try to solve it using Teamviewer and HP's drivers!
I think I've been quite hard nut hopefully clear, so please do something more than giving me a manual fro grannies.
Thank you.

Windows 8.1 and AMD radeon HD 6700m switchable graphics on HP pavilion dv7

Hello all
First would like to give positive feedback because my former problem was solved here but this thing appears again.
I have HP pavilion dv 7
i7 -2670QM (2.20ghz)
(8 GB Ram)
Windows 8.1
So my problem is with the switchable graphic as it is stated in the subject.
I had windows 7 previously and I had no problems with switchable graphics-
When I bought licenced win 8 the problems started and are continuing in my 8.1 upgrade.
I tried several thing, from turning off switchable mode in BIOS, turn it off in win desktop, uninstalling drivers or blocking drivers and it still doesn't help
It's a shame that with a computer like this I can't play a bit better games that I was able to when I had win7.
The main problem is that when the game instals it checks your computer and tell you if it's ok or not-and everytime I get that I have intel HD3000 graphics. and not AMD radeon hd 6700m graphic card.
Can anybody tells me how to fix this thing? I don't have any problems in display adapter-all drivers are good to go, i have the latest amd catalyst software.
It would be a shame to buy win 8 if 7 was good and better working on this issue.
Thank you for help

Switchable Graphics problem Aspire E15 E5-551G-T629

Hello, I've got a Aspire E15 E5-551G-T629, and the switchable graphics dont seem to work. I've tried several drivers, googled for hours and tried several methods even had the PC in for service for this and some other things and they said all was OK after the service. However the AMD r7 M265 won't be used no matter what.
Any idea what I can do to make this work? Because currently my pc is running games worse than my 6 year old 400 dollar laptop. (Not that gaming is the main objective here, but I'd like to be able to use the full power of my pc when required)
Cheers in advance

Thanks for your reply, but I have gone through every setting and changed what I could change. Here is what I have done: - Changed windows power settings to always be maximum- made sure acer epower management was the same- changed global settings in Catalyst to always be maximum (including battery on all of those)- manually added the games that weren't working and set them to high performance- added the games that weren't working to the 3d settings profiles- updated the drivers- updated the BIOS ...and probably more that I am forgetting, since I have been researching and tweaking settings for three days now. There are some games that it will automatically pick up, but the two games that I play the most (and that are the reason I spent extra money for a dedicated card) will only run off of the Intel. The most aggravating thing was that when I purchased this computer, I had no idea that it even had two graphics cards. The website only listed the AMD, and my previous laptop only had a dedicated Radeon card so I thought it must be the same. Why would it not list two cards if it had two? So when I had problems initially I didn't realize it was because the game was running off integrated graphics, so I was looking into other things. By the time I discovered it was the laptop itself causing the problems it was too late to return it.

Driver issues for Radeon HD 6750M switchable graphic card

Hello guys, took time for me to decide wether to join forums like this just to get real help coz goggle doesn't show any solution with my issue. i was able to update my video card with the old raptr app from amd and allowed me to maximize the feature of my laptop. after format i can't install these drivers "sp52929 & sp61216" for the said graphic card and the new and updated raptr is not somehow working. i get this error "The contents of the file cannot be unpacked. the executable you are attempting to run has been corrupted. please obtain another copy of the file, verify its integrity and try again" (monitored the download and its not corrupted or anything) or using the driver from amd official site (tried different versions like amd-catalyst-omega-14.12-with-dotnet45-win7-64bit, AMD-Catalyst-HDMI-Hotfix-Win8.1-Win7-Dec10 etc.), the installation is fine but it's not functioning and this is the error i get "no amd graphics driver is installed or the amd driver is not functioning properly. please install the amd driver appropriate for your amd hardware" and "you do not have the compatible vga hardware to driver" during installation it reverts my resolution back to 800x600 as if it conflicts with the Intel HD Graphics Family. tried uninstalling intel hd graphics family first and install the radeon but it seems that the driver itself really is the problem. does anyone here experiencing the same? or someone here who can tell me what's really going on? thanks i advance Referrence: http://h30434.www3.hp.com/t5/Notebook-Display-and-Video/latest-driver-for-amd-graphic-card-not-working/m-p/5150764#M113344

Please uninstall the currently installed Intel Drivers and AMD driver. (if present in Programs and features and device manager).Once all traces are removed, restart the PC and install the Driver file sp52929.exe becase (read the yellow text below) Download Link:ftp://ftp.hp.com/pub/softpaq//sp52501-53000/sp52929.exe Info:ftp://ftp.hp.com/pub/softpaq//sp52501-53000/sp52929.html This package provides the AMD High-Definition (HD) Graphics Driver and Catalyst
Control Center for supported notebook models that are running a supported
operating system. For notebooks with switchable graphics modes, this package

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?

GX60 Switchable Graphics Problem

Hi, I bought a GX60 Notebook (with A10-4600M, HD7970 graphics), and installed a Win 8 Pro x64 copy I got from my Univ. I proceeded to install the drivers and it seems everything is working fine...
Well, it only seems so - when I open AMD Catalyst and click on "Switchable Graphics Application Settings", the window just disappears.
When I try to open "Configure Switchable Graphics" from tray, nothing happens.
What could be the problem?
Edit:
I have already tried AMD Catalyst 12.10 and 12.11

Well i get the window but only the configure button are reachable with a slider and slide to the far right of the screen . I guess the drivers are still a bit buggy , did u try the latest 12.11 beta drivers for guru3d forums?(im not allowed to post externals links so i cant link it to you)

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!

About 2 scream!!! NOT SWITCHABLE GRAPHICS PROBLEM!!! Vid card seems 2 FAIL PERIOD!!!

I have the dv7-6135dx with the intel/radeon 6490 blah blah blah. You guys know the machine. Every time i try to find information regarding the bleeding ati card, all i can find is switchable graphics this switchable that, bios update for switcha....
When i disabled the dynamic in bios long ago, i lost ability to control screen brightness. Was very dim. Haven't tried it again.
When i plug in a monitor to HDMI port=nothing. Vga port works fine but i can not watch any video greater than 1.2 Gb without super skipping and digital breakup of the video (the million tiny boxes thing).
From ati site, auto thingy detected my card, gave me best driver, installed and when i open catalyst, it always says can not start because no ati device.
Before? I could watch 18gb hd vids with stunning performance. Now? Its dvd rips or choke and die.
Can SOMEBODY.... ANYBODY tell me what if any troubleshooting there is to see if the card is shot, or if there is a fix please? One that does NOT involve some gahrbajje about bleeding switchable bloody graphics?
Thanks in advance for any and all help in THIS matter.

I don't know if there is an "official" version, so I can just provide you with the link above. This script stops my radeon card when I boot. I only have as kernel parameter i915.modeset=1
and my intel card is always on.

Lenovo ideapad s400 switchable graphics problem..!

Simply the switchable graphic ia not working on my device. Is there anyone who solved this issue? I fed up with sending my laptop to service. They say ' you have no problem about graphic card ' The second graphic card has not been working since we bought the computer. ??? I will use that comp. for experimantel porpuses: ) Because it is useless with the onboard graphic card.

hi kuraysi,
Welcome to the Lenovo Forums.
Just to check, if you boot in Safe Mode, are you able to load Windows? If booting to Safe Mode works, perform a clean boot and observe. This will isolate any possible 3rd party software that might be inteferring with the Windows startup.
If that doesn't work and Windows is hanging up on the loading screen then we're probably looking at a corrupted Windows file or a bad hardware. In this case, you may need to:
1. Reload the system via the OneKey Recovery (note that all ways on the OS partition will be wiped)
2. If reloading Windows doesn't work or the machine freezes up then you're prolly looking at a bad hardware (possibly the HDD).
Let me know how it goes.

HP Pavilion dv6-6130eo, Radeon HD 6770M, switchable graphics, update Catalyst Control Center

Computer: HP Pavilion dv6-6130eo
I have installed windows 7 64 bit
Graphics cards: Switchable Intel and Radeon HD 6770M
So far, I have been using the graphics driver provided by HP including Catalyst Control Center, and it has been working fine.
I recently bought a new game: Wolfenstein:New order. I fulfill minimum requirements.
When trying to run the game, I am informed, that my Catalyst Control Center must be 14.4 or newer: Fatal error, and game cannot run.
How can I update my Catalyst Control Center to 14.4 or newer? Both graphics cards (switchable) should be working.
Thanks a lot in advance - This issue is really getting on my nerves!

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!!!

HP Envy m6-1178sa Switchable Graphics Problem

My problem is the AMD Catalyst Control Center does not seem to recognise the AMD graphics card (HD 7670M). It only gives me options for the Intel HD Graphics. It gives me the option of switching between the power-saving and high performance options, but the "high performance" option is noticeably worse than the power-switching one.
According to Windows Device Manager, both graphics cards are functioning properly, and their drivers are up-to-date.
Thanks in advance.
