Bios update is only performed when your motherboards utility chipset fail to update its drivers automatically like the sound chipset, network, bluetooth etc then you run the motherboard bios update however you must have not read the instructions before running the bios update it clearly states that plug in your power adapter or you must have the computer on an online power because if the power fails or the computer is interrupted during the bios update it will damage the motherboard permanently.
I can help you with recovering your data from the laptop.
