Hi,

Your machine came with FreeDOS, this issue is not small:

It use Intel HD Graphics 4400. All drivers for this machine should be on the following link:

Your machine only needs   Intel High-Definition (HD) Graphics Driver.

You need to install  Intel Chipset Installation Utility and Driver and  Intel Management Engine Interface (MEI) Driver and reboot the machine first.

After all of that you need the following driver to use Hotkey:

Hi mate, found the reason for my problem it was coz my driver was disabled. Finally found it, really thanks a ton bro. 🙂

I'm having one more issue to deal with. If u can, can u please tell me the way in which i can use f5 key to refresh my pc,because each and every time i need to press fn + F5 key to refresh my pc while others do it with just f5. If u can find me a solution for this problem that would be much appreciated.
