Hello! I am very happy with my laptop, but it does not have a touchscreen. Can I just buy and replace it, or do I need to check whether the hardware can power it? Please excuse the lack of technical language. I don't know where to check this. Any help is greatly appreciated. I can buy them, I just need to know if they will actually work!
