if you do attempt to update the BIOS again... besure to have the laptop connected to the AC power,, and make sure the battery is at full charge before starting....

and by no means should you ever unplug, turnoff,, or try to stop a BIOS update once it has started.... if it's under warranty, you can always tell the manufacturer that the PC froze in the middle of the BIOS update and will not continue... then ask them what you should do.... they will then schedual the laptop for repair...

and never tell them you pulled the plug, or reset it durring the BIOS update,, that gives them reason to blame you and justification to refuse to cover it under warranty

later,
