Hello Everybody,
I want to share my findings about switch issues and a fix for Code:43 error instead of waiting for a BIOS update.
Note: This may apply as well as to Windows 8, not tested yet though.
Notebook: HP Envy Ultrabook 6-1000et (Core I5, Intel HD Graphics 4000 & AMD Radeon 7670M)
OS: Windows 7 x64
PN: B6H42EA
SN: Not needed.
Product Specs: Here
Issue: AMD driver from most of offical HP softpaqs generally can not be installed in anyway, despite several of them could be installed but still AMD is reporting Code:43 and AMD Catalyst Center won't start stating that AMD GPU does not exist on system or its driver or hardware unit is failed, not supported.
Attempts: I tried almost any AMD softpaqs available through HP web-site & HP Support Assistant Scans and none of them was helpful. So decided to go deeper into the trouble. Recovery done, test OS installed, Bios updates, rollbacks completed. Tried like ten softpaqs of AMD Graphics still not working.
Below are steps that fixed the problem.
(Take your precautions as I don't want your unit to be broken after all, do not try these steps if you feel like your computer will be failed or won't survive steps.)
Steps:
1. Make sure your BIOS is the latest.
2. Uninstall AMD & Intel Drivers from device manager with a tick to delete software as well. Check Programs and Features to locate any remaining graphics softwares.
3. Download driver sweeper or similar application to purge remaining dlls of graphics software. Disable Windows Update Driver Auto-Install settings including downloading stuff from Microsoft Update.
4. Download Intel HD Graphics 4000 Driver from Offical Intel Web-site:
5. Download AMD 7670m Driver directly from AMD Web-site: Direct link does not work, go to site and download.
6. Install Intel HD Graphics 4000 driver and restart computer. You will notice that Intel will be working fine now. But AMD still has Code:43 with a warning icon on Device Manager.
7. Install AMD Driver and make sure you give permission 'Trust software from this publisher (AMD)'. Restart Computer.
8. You may (As I did) notice AMD will still have Code:43 but it is already been installed. Switchable graphics shortcut does not still exist on right-click menu of Desktop.
9. Now, go to HP Web-site and download 1st (Original) version of your BIOS and install it.
10. Get back to Device Manager and check Display Adapters: Now both AMD and Intel is working fine and you see 'Manage Switchable Graphics' does exist and working on your Desktop right-click Menu.
11. Install latest BIOS version of your notebook, and you are done.
What do you have on your computer now?
- Latest BIOS update.
- Latest Intel & AMD drivers installed.
- No more Code:43.
- Switchable graphics that really work.

Now to talk about PES-2013 and AMD relationship on HP notebooks.
- After main problem solved. I decided to install PES 2013 (Pro Evolution Soccer 2013) to see if it really won't be assigned to AMD at all or not.
Applications Used:
- PES 2013
- Unigine Heaven Benchmark
Notebooks Used: (Numbers are as IDs stated after the list below)
1 - Envy Ultrabook 6-1000et B6H42EA (4000 & 7670M) Windows 7
2 - Pavilion 15-e060st E1T76EA (4000 & 8670M) Windows 8
3 - Pavilion 15-n096st E7G99EA (8610G & 8670M) Windows 8.1 Pro
4 - Pavilion G7-2110st B7S27EA (4000 & 7670M) Windows 7
5 - ENVY 14-2050ET BEATS EDITION LS776EA (HD Graphics & 6630M) SUPPORTED on BOTH BIOS & DESKTOP COMPLETE SWITCH RATHER THAN ASSIGNING APPLICATIONS. Windows 7
6 - Another Pavilion 15 with only Intel HD Graphics 4000 on it. (Can't remember it's specs.) Can add details if requested later. Windows 8
Resolution:
After Assigning PES 2013 to High Performance, it will still show Intel HD graphics activated on settings.exe (Pes-2013) but it's quite clear that game is actually running on AMD Graphics regarding notebooks number 1,2,3,4. There were no FPS drops and quite seamless gameplay experience.
I have confirmed this by running Unigine Heaven Benchmark on all notebooks:
Number 1: Allows application running only on AMD, it's locked.
Number 2: Application states it's on Intel 4000 but it's clear that by observing FPS, it's running on AMD, confirmed by checking FPS value of benchmark from Number 6.
Number 3: Application does not state which GPU is activated. But again by FPS, it's on AMD.
Number 4: Application runs on AMD.
Number 5: A very lucky unit which has Switchable Graphics are fully supported by BIOS. On this unit, it's always correct what you have assigned, PES-2013 and benchmark application reports were fully correct. Only on this laptop I seen Settings.exe (PES-2013) reported AMD is the selected GPU. This is very important finding.
Number 6: Reference Unit.
These are my test results, it may vary on setup/notebook you have used. But seems like there is not any problem at least on my side.
I've posted these to help people who are in need. If it fixes your problems, then I am glad to be helped out.
Result may not be the same for your computers but it worthes a try.
