I had this problem for ages. I looked online and finally found ONE post that made a suggestion that actually worked.

The solution to the on/off/on/off problem is to go to the "Power Options" and select the "Power saver" radio button option. You can then change the internal contents of the "Power saver" options to whatever you wish, but it must be selected.
I don't know why it makes a difference; it may be the combination of several items... may be the option itself. In either case, My fan turns on VERY infrequently now even when watching a movie. I suggest you set the option to "Power saver" and see test things out. From then, you can tweak your heart's content.
Hope this helps.
Quite often, laptops will have two graphics chips.
Will AMD graphics cause conflict with the installed Intel graphics driver?
Not unless something goes wrong, in laptops they usually supplement each other. Your Intel graphics will be used for tasks such as browsing the internet, Microsoft office and the like. If you were to boot up a 3D application such as a game, the Intel chip will hand over to your AMD card who is more suited to the task. This behaviour is configurable in the AMD catalyst control center if you wanted the AMD card to be permanently in control (Not needed.)
When it downloaded RADEON, is it not for the graphic driver?
Yes it is, the model name for AMD graphics begins with AMD RADEON. You will have 2 graphics drivers, one Intel one AMD.
When Intel graphics was installed it has HD control panel but `RADEON
doesn't - from the third picture
Those are the two tabs, display and render. Display = Used to browse your computer and normal tasks. Render = Used to perform demanding graphical tasks (Gaming etc.)
Forcing AMD/ Enabling automatic switchover
To verify that the switchover from AMD to Intel is automatically occurring, you can do the following (May vary slightly according to versions of Intel Chip):
- Right Click your desktop, then graphics properties
- Click "3D"
- General Settings - Balanced (Performance for permanent AMD control) & Application optimal mode On.
- Go back to the control panel and click "Power"
- Plugged in power plan set to balanced (Maximum Performance if you want your AMD card to permanently be on)
Now on the AMD side of things:
- Open Catalyst control center
- Click powerplay
- Have Plugged into set for maximum performance (Your choice for battery.)
- Go back to the CCC home and click switchable graphics. Set plugged into optimize for switchable graphics or Maximum for permanent AMD control.
- Go back home again. In switchable graphics application settings, you can set per application if it should use power saving (Intel) or maximum performance (AMD).
Now you mentioned in your comment an emulator needs to run on Intel. Add it as an application in the switchable graphics application setting and force it to run in power saving.
If you're having problems beyond this, ensure that both the Intel and AMD drivers (and CCC) are up to their latest versions, they should both pickup each other's existence.
Best Answer
Why do you "hope you don't have to reinstall the drivers"? That's most likely the fix. It's not hard. In fact it's extremely easy. Why don't you try to do that?
