Rick and I just looked at ours (Aspire 44B). For us, it's in the basement, passenger side, just in front of the panel with the switches for the battery cut-offs. It's mounted on the ceiling and covered by a plastic shroud. We can see the power wire, a USB plug, cable plug and a reset button. Can't see any way to turn the power on or off without just unplugging it but doing a reset may help.
