A failed BIOS update will break the motherboard CMOS. If your warranty has already expired, you have to weigh the pros and cons in attempting to install a BIOS update. A replacement motherboard is costly. My instructions for installing a BIOS update on a Laptop* Either the external power adapter is connected to the Laptop or the battery charge is at a minimum of 75%* The Laptop is not connected to any dock* Download/Save the BIOS file to the Windows desktop* Restart the Laptop* Disconnect all external devices (HDD, monitor, printer, etc.) from the Laptop* Close/end task all unnecessary software applications (Browsers, Dell SupportAssist, Dell Update Application, Steam, Anti-virus, etc.)* Find the saved BIOS file on the Windows desktop* Right click the file and choose, "Run as administrator". Note, you do not need to "extract" the file. Just run it* Follow the prompted instructions. The Laptop will reboot on its own, do not force it
