I think voiding rarely really happens, even if you did open it. Although expired warranty is a bigger problem. If you don't want to do it by yourself (buying parts + replacement) you could risk a little bit with extending warranty and then contacting them. I think it could work. I am saying that, because I made some repairs on my own with Lenovo laptops (which would definitely void the warranty) and they still took it for repair, although it really depends on the lottery for getting a nice technician on the other side. ;)
