Notebook Hardware and Upgrade Questions

My HP Spectre x360 was a super awesome computer. I really enjoyed the design, the keyboard, the touchscreen response and it's overall processing speeds. I enjoyed it so much that I even recommended it to friends as a college student, and those friends then went on to buy this laptop.

All was well until one day my laptop crashed. Thinking it was the battery dying, I tried plugging in my AC adapter. Unfortunately, it didn't charge my laptop. After borrowing my friend's charger that I knew worked on my laptop, I found that this also would not charge my laptop. Running out of options, I sent my computer to certified HP service center and apparently the problem is with the motherboard and the DC in port.

I was very disappointed to find the the cost of these replacement parts would be upwards of $650, which is more than 50% of the cost of the laptop itself!! This was incredibly disappointing news to hear especially since this laptop is only a year and a half old (conveniently outside of warranty) and is supposedly a higher end model. One would think this laptop should last for at least 3-4 years. On top of that, I now have friends and family who got this laptop on my recommendation and will likely suffer from the same fate.

As a college student, this is a major inconvenience. Not only do I have to juggle borrowiong laptops and using public computers to finish daily assignments, I am now expected to pay hundreds of dollars for a replacement part that should not be malfunctioning (funds that I don't have I might add). I will no longer be recommending this product and can continue to spread the word about this across my campus.

Is there any way this laptop can be returned or repaired economically, or (dare I say it) for free?
