A. B. C. D. E.B.
Based on the symptoms described, the MOST probable cause of the issue is a damaged AC adapter.
The fact that the power light goes on and then suddenly off when the power button is pressed indicates that the laptop is receiving some power but not enough to keep it running. This is consistent with an issue with the AC adapter.
Replacing the battery allowed the laptop to power on, which suggests that the battery was not holding a charge, but this does not necessarily mean that the battery was the root cause of the problem. It is possible that the battery was draining more quickly than usual because the laptop was not receiving enough power from the AC adapter.
Additionally, the fact that the problem reoccurred the next morning after working without issues until the end of the day suggests that the laptop is not receiving enough power consistently.
Therefore, a damaged AC adapter is the MOST probable cause of the issue. Swollen battery, improperly seated RAM, cooling fan failure, and imminent hard drive failure are less likely to be the cause of the issue based on the symptoms described.
