Dell Inspiron 7720 SE - Gpu boost is turning off
I have decided to create a new post regarding this issue, which wasn´t solved at last bios update (A12)..
GPU boost (OC to 835MHZ) is not working anymore and stick the frequency at default level all the time (745MHZ).
This happens when this laptop is disconnected from AC and it´s permanent stuck till you remove and re-insert the battery to reset somekind of memory.
I would understand if this feature will work on battery to save energy, but this is clearly a bug and after reconnecting AC, it should enable GPU boost again, but it doesn´t.
So, everytime i accidentally disconnect my laptop from power supply, my GPU boost is turned off and i have to painfully turn off the laptop and re-insert the battery to make it work again.
Many users registered this issue on forums all around the world... Please, don´t say it´s a feature to protect the laptop....
Thanks for your help!

In device manager if you go to view hidden devices does the 650m appear? http://thewindowsclub.thewindowsclubco.netdna-cdn.com/wp-content/uploads/2015/03/show-hidden-devices-windows-600x402.jpg
Also I wouldn't use Windows 7. The laptop comes with Windows 8. Windows 10 should work fine, I'm using the 17r 7720 SE with Windows 10 with latest a17.
Biggest problem for us to help is language barrier.
My steps to fix would be:
Install from fresh Windows 8 or 10.
Install latest Intel driver from Intel driver update
Reboot
Install latest nvidia driver from nvidia.com
Reboot
Install chipset driver from Dell.com
Reboot
Install bios a16
Reboot
See if GPU still goes missing still.
Install bios a17
See if GPU still goes missing and if GPU boost.
Notes:
Make sure bios correctly installs each time. You can tell when you start computer in bottom corner it will say a16 or a17.
Make sure you have exact same model. How do you know for sure you have 17r 7720 SE?
Did you own laptop from new or second hand? There may have been a reason it's sold if you bought it second hand.
Outside of this apart from using the custom bios I linked before there isn't anything else really to try. I would suggest contacting Dell support and asking them. It could be a connection or hardware problem. If it doesn't work after these steps I'm not sure what else to try.
Good luck!

Forgot to mention. If it is shown hidden devices with error code, goto properties and screenshot error code.
