So I had an issue with my GPU on my new laptop, an Inspiron 15 7567, and I initiated a exchange for a new machine through Dell, a very seamless & painless process besides not having a laptop for a week while they revived my faulty one and sent me a new one. Since the laptop is only 15 days old they offerd to exchange it out vice going through the warranty RMA process, which I happily accepted. However instead of getting a new 7567 in exchange for the one with a defective GPU, they sent me a new Inspiron 15 7577, which is the newer model of mine and a $150-200 upgrade. This is clearly an error on their part and they just upgraded my laptop by mistake. I do feel as if I should say something and tell them of the mistake, but I dont want to have to send this one back again and wait another week or so since its the weekend for my laptop. Also the warranty is suspended until I register the new laptop and im worried that if I dont say anything and they discover the error of their own accord that I may get my warranty voided. Does anyone have any thoughts on how I should proceed? I feel that honesty is the best policy in any situation, & I dont mind returning it for the correct mode, the one I purchased; I just dont want to wait any longer to ship it back to them and then wait again for them to ship me the correct model. I suppose they could always just say thanks for letting us know and keep the new model on us, but I gather they will want the more expensive and newer machine back, thus having to wait out the shipping process.
