The AC power adapter is used to recharge the battery in a notebook computer and to provide dependable power for operating the notebook for long periods of time. If an AC power adapter fails, it will not recharge the battery and it will not provide power to operate the notebook without a battery.

The OP was asking about an IC inside their power adaptor, they were not asking what the power adaptor is used for, I'm sure they are well aware. Further to this the device they are talking about is a printer not a laptop.

All of your answers seem pretty low quality one shot answers with ZERO follow up.
