Hello everyone,
I'm experiencing an issue with my Alienware 15 R2 (Service Tag: DL7NN32). The laptop works perfectly when connected to the AC adapter — it powers on and functions normally.

However, when I was diagnosing the issue, I turned the laptop off, checked the board, etc. When I put everything back together, the laptop was charging (I inserted the charger and then turned the laptop on). After unplugging the charger and plugging it back,... -
