Your laptop has "hung" while performing the BIOS update.
1. Power off the laptop and unplug from the power brick.
2. Leave the laptop disconnected from power for about 10 minutes.
3. Power up the laptop and try to get into the BIOS.( Press and hold the F2 button , then click the power button. DO NOT RELEASE the F2 button until the BIOS screen display.) Most of the time what has happened is the boot drive has been changed. Simply make the change back to the correct boot drive.
$ if you are unable to get into the BIOS then return the laptop for repair, replacement, or refund.
Good Luck
