The bios update instructions say that you need ac power -and- a charged battery. What is the charged battery (which I don't have anymore) used for? Will the update succeed without one?

Thanks again.

The charged battery is expected to be in place as a failsafe in the event that AC power is interrupted during the BIOS update. If the update is interrupted by a loss of power the BIOS will be permanently broken. Depending on the machine (I believe) some may let you take the risk and some may prevent you from moving ahead without a battery.

I guess I'd rate the risk like this: If the laptop is solidly plugged into the wall and the AC power is reliable and the AC adapter is reliable (no flakey cord) and you don't do anything that risks bumping the laptop or cord during the BIOS update then your risk should be low. But by doing so you run the chance of killing your PC. Is avoiding that chance worth the price of a new battery? Only you can answer that.
