Hi guys, I'm new here and I need some little help with the BIOS of my new Alienware 17 R2. I'm gonna try again to start a thread about that, the first one kinda disappeared.

Hello everyone, I received technical intervention on my Alienware 17 R2 some days ago, the Dell technician replaced my defective frontal speakers and also motherboard, when rebooting the system he entered again my Service Tag on the BIOS but I think he did something wrong and now the BIOS shows Alienware 15 instead of Alienware 17 R2 as Product Name, I know there are different ways to edit these parameters, I'm asking you guys help or a software / tool to fix this error. TL;DR: I need to edit the Product Name on BIOS to change it from Alienware 15 to Alienware 17 R2. I'm attaching a picture. Thanks in advance for your help
