Compaq Presario CQ56-220CA Black US Replacement Laptop Keyboard (KEY612)

I know nothing about computers. Spoke with a computer repair man, he said he was going to go on Amazon.com to look for a keyboard that I needed to replace on my laptop, then he was going to change it, told me how easy it was. So, I went to amazon.com did what he did, watched a you tube video, and my son replaced it in literally 5 minutes, start to finish. It was very easy to install and works great, just like a new laptop.
