Ceiling light turns on when outlet draws power, followed by power loss
It is possible that the outlets in that room are all wired into the dimmer switch such that simple lamps plugged into the outlets can be dimmed. If this is the case computers and monitors will not function properly when plugged into a dimmer circuit.

The simple test you can try is to get a simple incandescent light (lamp, trouble light or night stand lamp) and plug it into each outlet in that room and see if it responds to the dimmer switch in a normal manner. If you get other results than dimmer behavior then that is a trigger event to get the landlord or apartment manager involved.
