Question about Acer Aspire m5640 PC Desktop
Monitor says no input
It's for the CMOS chip that holds the BIOS software that supports your motherboards info. That's why you have the correct time and current hardware configuration even after being unplugged.
No input means there is no communication with the video card. Try reconnecting monitor cable. Or, possibly re-seating the video card if its an add-on.
