Hi all, need some help. I have a Samsung NP370E4K-KD2BR, which as a 5th Gen Intel CPU that works fine when running with the charger plugged in, but has soon as I remove it and it's running on battery the screen backlight goes off.
Tried different battery - no change
Tried different screen - no change
Removed the plastic film from the screen inverter and looked for pwm signal which as about 3.3v when running with the charger plugged in, when I take it off the voltage drops down to 2.232v, so my best guess is that the EC is not providing the correct voltage.
Would it be possible that a ME clean could solve this issue?
Best Regards
