Never run any updates especially bios update without using the adapter plugged into power source. That is to prevent a shutdown during the update which can brick the computer. Even with the adapter plugged in, a dead/dying battery will prevent bios updates.
Does the computer work on battery alone? The battery meter could wrong when the adapter is connected. Your model is 5 yrs old now and the battery might be wearing out.

go into setup - F2 at powerup. Is the AC adapter correctly recognized, or does it show unknown?
