There are cases where you must update the system BIOS on a laptop when the AC Adapter cannot be determined or is not available. This process may also be needed if the computer battery has failed or is not installed in the computer. When you attempt to update the BIOS within Windows, the update program detects if the AC adapter and a charged battery are present or not and will not continue until it is plugged in. If you must flash a BIOS and the AC adapter is nonfunctional or unavailable, the battery is dead or removed, there is a way to force the flash.
