Issue with Dell XPS 15 9570 (Screen not turning on)

Hello everyone,

I have bought my laptop around 4 years ago. Just around 3 weeks ago, I experienced a major issue.

• The issue did not happen prior to this.
• Laptop randomly dies (even if fully charged)
  • It turns on, but the screen does not
• Charging light (one at the bottom), flashes 1 white, followed by 2 amber
  • This apparently indicates there's a CPU failure. However, that is not the case
• To fix this (3 weeks ago), I have:
  • Removed the bottom case (it immediately turns on but later turns off)
  • I removed both RAM sticks and blew Air into them
  • The laptop did not have any problem until after 3 weeks (now)
• This is no longer working
  • It works when I remove the case. However, dies after

What could be the issue here, and the possible solution? Did anyone else experience this, it's very frustrating when a laptop has this problem without any reason after only a couple of years.

Thank you in advance!
