unable to update Dell Alienware 14 System BIOS because it require battery life at least 60% but my battery spoiled. So i unable to update. Any kind of solutions that can help me to solve it? Thank you very much.
Hold on doing the BIOS update until you have replaced the battery. While you can force flash a BIOS without a battery, a single power drop during the process will brick the mainboard -- it's a bad idea.
