Defective XPS 15 9530

I purchased this as a top of the line laptop with premium specs and a very premium price. 

the unit has a terrible power management issue. Once you plug in something to the right USB-C port the original Dell charger stops powering the laptop and the battery runs out. Basically you are working plugged on the the power supply and after a few minutes the laptop starts to stall everything becomes super slow and you get a message that your battery is extremely low. 

At this point there is no way to solve this. Not even unplugging the external monitor from the USB-C. It still continues to dry out the battery and you must shut the unit off completely and let it recharge while off for several minutes before you can even turn it on. If you don’t wait a while with the unit in it simply will not power on.  

I was traveling when I purchase this laptop but reported the issue shortly after the first 30 days of owning it. 

They sent a tech guy to replace the motherboard!! This is absolutely crazy. Take the new laptop apart in front of you and replace the heart of the machine and the most expensive part. Worse yet, they assembled it wrong and had to come in the next day to assemble it again!!!  Super crazy but that isn’t even the worse part:  The power issue was not resolved!!! New motherboard, same defect. 

It is clearly a design problem. 100% Defective product at a very high price. 

During the first year of warranty ai contacted Dell at least 50 times. I continuously got agents with Hindu accents that very politely wasted my time in:

1. Asking the same stupid questions every time. 
2. Offering apologies and a solution. 
3. Updating bios and running all sorts of tests. 

But most importantly NO SOLUTION. 

After almost a year of battling with customer support  I decided to purchase a warranty extension hoping that the problem could be solved. 

Now after owning the this for 14 months I came across this forum to realize that I got ripped off by Dell. 

They give everyone the same run around and they don’t solve the problem EVER. 

What a shame. I expected much better. 

If anyone can recommend how to go about this Inwoukd highly appreciate your suggestions. 

Thanks
