This behavior could indicate a hardware issue with the laptop, such as a problem with the battery, charger, or charging port. It is important to address this issue as soon as possible to avoid any potential damage to the laptop or data loss. In some cases, it could also be a software issue, such as a driver conflict or incorrect power settings. Before assuming it's a hardware problem, you can try updating your drivers and checking the power settings to make sure they are configured correctly. If updating drivers and checking power settings doesn't resolve the issue, it is recommended to contact Dell support.
My Dell G15 5520 turns off completely when charger AC is connected when the CPU and GPU are under heavy load. When AC connecting while the laptop is idle, it does not happen. Also after the laptop shuts off, it starts again and works like nothing happened. Is this something to worry about or is it just a software issue ?
