The link you've provided won't work since it's a location on your desktop machine. If you'd like to pass on a link to this thread, please host your image on Photobucket or Imgur and parse the link in your thread.

Unfortunately it's not good practice to mix and match sticks of ram but for the sake of this thread, you can go with this but you will have to keep in mind that if your laptop doesn't boot up or shows instability you can blame the new stick of ram for your issues. To which I'd simply say, buy a 2x4GB DDR3 1600MHz kit and sell your existing stick of ram.

Might I ask what your laptop's make and model is?

The processor on your laptop is that of an Intel i5-560M which can only cope with a maximum frequency of 1066MHz from your ram. Technically you can put in DDR3-1600MHz ram and the system will downclock it to DDR3-1066MHz.

Given that the prices for DDR3-1600MHz are better than DDr3-1066MHz kit's and that you already are working with a high density stick of 4GB of ram,

you can go ahead and pick up this kit while you sell off your existing single stick of 4GB of ram.
