I bought an ALIENWARE m15 R7 around 1 month ago. After 2 weeks of usage, while I was gaming I had massive fps drop. I realized that the charger wasn't plugged in, and switched it on causing the laptop to instantly crash. I turned it back on and it had stopped charging. After a bit of troubleshooting, I decided to press the power button for 30 seconds and it turned back on and charging worked fine.

Fast forward today, the same happened but this time it was when I put game settings to ultra it crashed. This was at the end of an 8 hour game session. Then I again had to drain residual power (pressed power button for 30 secs) and it started charging again.

Is this normal? Could it be that its just due to the power surges or stuff like that?
