Glad things worked out, but for the future, there's a few things to keep in mind. The 14-Day return policy is set by Best Buy. This is not the warranty on the computer, it's simply the store policy for returns.
What your friend was thinking of doing is considered
Return Fraud. While I can't find information regarding laws that govern this, that isn't to say there wouldn't be repercussions. Back in 2006, a figure of a loss of $9.5 billion dollars was
stated. Ultimately, that loss affects the consumers as stores seek to recoup that money. In addition, they've sought to tighten their return policies, making it harder for honest people to return unwanted or defective products.
Acer, as the manufacturer, would most likely have offered a
limited warranty, which lasts for a year or two, depending on the model. This has nothing to do with Best Buy and their policies. It sounds like this is what your friend used to get service, as the text of the
warranty states that they'll provide service, but the customer is responsible for shipping and handling.
After the period of the limited warranty, they'll still provide service, but will charge you for that service. Of course, after a year or two, the possibilities of finding the exact model your friend purchased for sale diminish, so at that point, it would be up to your friend whether they wanted to buy a brand new computer or pay for the service.
Luckily, it sounded like things worked out for your friend. I had a Dell monitor under warrant about 7 years ago that stopped working. It took hours with Dell customer service to convince them I had a warranty, that the monitor was covered by the warranty, and that they should replace it. They finally agreed, but after the expected delivery date, the monitor never arrived. After a few more hours on the phone with Dell, where I again had to convince them I had the warranty on the monitor and that the monitor was covered by it, they had trouble confirming the monitor was sent. Eventually it all got resolved.
Some key things to remember in the future are that you sometimes have to be persistent. You also have power as a consumer.
Social Media has opened up a new means of seeking help for problems. Most companies don't want the negative attention an upset customer can bring and often, through things like Facebook and Twitter, you can get a hold of somebody, as companies are starting to get that not responding to problems brought up by social media users can be a black mark against them.
Last year, my daughter's phone stopped working and after dealing with the local MetroPCS store that handled warranties (there is only one store authorized to handle warranty issues, the others are just authorized to sell MetroPCS products and services), she got a replacement, which suffered from the same problem. A quick search online found that others who had the same model, manufactured around the same time, had the same problem.
Fed up with this problem and the store's attitude about it, I took to Facebook and Twitter and MetroPCS comped me for a month of service. I also hit up LG's Facebook and Twitter sites, but they were less helpful. Of course, with cellphones, they can play the, "Oh, we're just the manufacturer, you have to go through the dealer/Oh we're just the dealer, you have to go through the manufacturer" game. LG was willing to fix it, but they need to get the phone first, diagnose the problem, and then, depending on whether or not they found the problem to be their responsibility, they could turn around and require you pay for the service.
I had the same issue with a Samsung phone I dropped in water. I was honest with them about it and they told me to send it in, but after they received it, they determined that it would cost me to fix it. I was not willing to pay that much, so they sent me the damaged phone back. I wasn't upset about that, beyond the fact that the customer service representative I was dealing with made it seem like it would be easier than it was to get it fixed.
TL;DR: Check with the manufacturer warranty. Best Buy's 14 day return is more for a customer who decides that the product isn't what they wanted, versus a defective product (which isn't to say they won't replace the product, though some instruction manuals and warranties direct you to contact the manufacturer and not the store where you purchased the item for help with a defective item). Most electronics will come with a limited warranty from the manufacturer. If all else fails, take to social media to try to apply pressure to these companies to get a problem fixed.
And, honesty is the best policy.
