Cannot find Additional drivers (proprietary) for my nVidia graphics card

[Nidal R]

The Software & Updates program cannot find the proprietary drivers for my nVidia 620m graphics card. Unity cog menu> 'About this computer' doesn't even detect my nvidia card. It just says I have Intel® Ivybridge Mobile.

Am on Ubuntu 13.10 which is fully updated.
My Laptop details :

Model : Acer Model V5 471G
Processor: Intel® Core™ i5-3317U CPU
Graphics : Intel® Ivybridge Mobile and nVidia 620m graphics card.

I tried installing it manually.. turned out to be a mess . Right now my laptop is running with fan on full speed, cannot adjust screen brightness, very low battery life compared to my windows 8 installation, and hot as a friggin toaster. This problem is seriously affecting my work. Any suggestions for good workarounds are appreciated.

This is not a bug with software-properties. It does not offer the nvidia driver for install because the nvidia driver should not be installed directly on Optimus/hybrid systems.
