Lights flicker when laptop is plugged in

I have a two year old laptop and if it is plugged in all the lights on that breaker flicker even if the laptop is not on. I tried plugging in just the power supply without the laptop and no flicker then plug in the computer and then the flicker starts. I don't know if the battery is causing it or the computer is going bad. I am going to see if it works plugged in and the battery removed. Any ideas? I hope this is the right forum for this post.

Update: I removed the battery and plugged in the laptop and no flicker of the house lights, as soon as I turned on the laptop without the battery the lights started to flicker so I guess it either the power supply or or the computer and not the battery.

Some laptops will still charge internal battery from a connected AC power supply with the laptop's power switch OFF. If the lights still flicker when the AC power supply (plugged into a different breaker powered outlet) is plugged into the laptop, then the AC power supply or the laptops battery is defective. Is the AC power supply the one that came with the laptop? Also provide the brand and model numbers of the laptop and AC power supply.

Thank you, I plugged the laptop into another outlet on a different breaker and there is no flicker. I tried plugging in a three prong appliance into the outlet that did cause the flicker and the flickering started so I guess the problem is in the wiring. I will call the landlord today. Thanks for the help.
