Ok so, I've got a 17" Aspire 5, when I put it under any sort of medium high load it just stops charging and show blinks the status LEDs which I suppose mean it get's in power safety mode. Only notable things I can see being an issue are my CSME firmware which isn't the one from Acer because the Acer one was a vulnerable version relative to the current firmware I have installed (latest for KabyLake / KabyLake Refresh), the PC being only able to supply 0.05W to the battery on load spikes, and the slightly loose power inlet.

I mostly suspect the latter but it seamingly started happening...

I would like to share my experience about charging issues with Dell power supplies with the tech community. I am working on a Dell Inspiron 5590, Mainboard 18778-1 with charging problems. The device can be switched on and works so far, only the message appears at startup:

Alert! The AC power adapter wattage and Type cannot be determined. The battery may not change. The System will adjust the performace to match the power available.

The power supply unit is not recognized in the Bios and the charging process is set to "idle". I use original Dell battery, type...

PROBLEM-WHEN I PLUG THE CHARGER WITHOUT BATTERY THE CHARGING LIGHT BLINKS AND WHEN I PRESS POWER BUTTON THE CHARGING LIGHT STOPS BLINKING AND STAYS ON BUT THE POWER LIGHT DOESNT TURN ON AND LAPTOP ALSO DOESNT TURN ON NO FAN SPINS NO KEYBOARD LIGHT.

CHECKED- ON S5 STATE TGE LAPTOP HAS 5V ON USB 3.3V BUT I DIDNT GET 1.8VOLTS ON BIOS PIN NO 8 WHILE PLUGGED IN AND EVEN ON S5 STATE.
