The keyboard is just seam to be built into teh laptop..If it makes issues you need another one ..and it can be changed if you remove the hinges cover and after that will have a few screws keeping it in place and will slide toward the display about an inch and will be able to get out ..It is connected to the main board with a ribbon and a plug ..and it is kinda short ..so do not pull it higher than necessary ..unplug i t..plug the other one ..slide it or clip it in place ..screw it down and clip in place the hinges cover and that's all ..restart an will work ..
here is a video about the procedure if you think visual info will make you understand the procedure better
if you do not have a keyboard to match ..you can use a usb based one until you get the correct part ..Just plug it and let windows install it and will be able to work ..
