Microsoft wired keyboard 200 USB problem

Last week I got a new Microsoft Wired Keyboard 200 for Business - Black to replace my old PS/2 one in windows 8.1 64 bit . As soon as I installed it  I observed strange behavior.

After some seconds the leds would turn off and it would become unresponsive until the third or fourth keystroke. For example if I typed "microsoft"  then "crosoft"  would appear on screen.

Also if I kept a key pressed for more than a few seconds when playing games for example the PC would make a strange noise and keep that key stuck.

This behavior was irritating and made using the PC impossible. 

Fortunately a solution was found. And ironically it was not a problem after all it was a feature.

It turns out that the keyboard is set to go to sleep after some seconds by default in order to save power. Genius!

So in order to undo this madness I had to turn off all kind of arcane settings in windows control panel.

Go to control Panel -> Devices and Printers -> USB Keyboard ->Hardware tab->select usb input device -> properties->change settings->Power management tab->unselect Allow the computer to turn off this device to save power -> Ok

Here is a video showing these steps

And the problem was solved.
