Yeah, I talked again to the Dell Technical support and they completely resolved it. Thanks!  I guess moral is to make sure I'm never gonna give up on the issue, never gonna let it down! (until it's fixed, of course, which it is now)
Hi!I've been having a few frustrating issues with my new XPS9520: - there is a weird screeching noise coming out of the bottom of the laptop. It's not fan noise, since the fan ramp doesn't change the sound. It's almost coil whine-esque, but more annoying. - many of the keys creak when being pressed not dead-center, and there are keys (like "b") that feel extremely mushy compared to others. - An app that worked for a few weeks, microsoft flight simulator, no longer opens. Even after a clean install of windows, this app keeps crashing. It works fine on other computers. - The same wobbly trackpad issue. Now, the XPS is an extremely expensive laptop, and this one is only two months old, so it's quite frustrating to have paid this much and still get a laptop with QC slips. I also cannot spend weeks without a laptop while dell shuffles it back and forth to patch up mistakes, since this laptop is essential for my job. Dell's support hasn't been able to resolve these issues, which is also terrible, since they should support a two-month-old laptop better. In fact, the agent simply ended the chat when I described the many issues with this laptop... and then marked the service ticket as complete. This is not ideal, I think. What would be perfect is if dell could ship me a new replacement unit, and of course I'd be happy to send this unit back for analysis. If Dell does resolve this well, I'll definitely post again and give my updated thoughts.
