Computer Battery

The lamp in my office is plugged into a wall plug that is connected to the light switch on the wall beside the door.  I had been using Laura's old speakers on my computer and the speakers and the computer were plugged into the wall.  I was working away and suddenly my computer said the battery was low and I should replace the battery.  I was freaking out.  I couldn't figure out why my computer wasn't charging even though it was plugged into the wall.  I didn't want to have to replace the battery.  After a while, I realized that my computer was plugged into plug for the lamp and since the wall switch wasn't on, there was no power coming out that plug.  So I went to the sun room and borrowed the multi-plug thingy and plugged that into the wall plug so that I could plug the lamp into one plug and the computer and the speakers into another plug and both of these plugs were plugged into the socket that worked.
