I was in the middle of updating the BIOS on my ASUS ZenBook S14 when the power went out, and now my laptop is stuck on a black screen. I've tried rebooting it, but the keyboard lights keep flashing and the fan occasionally spins up. I've attempted to fix it by using a BIOS update on a USB stick, but nothing is showing on the screen. Is there any way to recover my laptop, or is it beyond saving?

Unfortunately, it sounds like you might be out of luck. Unless you know someone who can replace the BIOS chip from a donor board, you might need to file for RMA. Keep in mind, user actions like this often lead to rejection. If that doesn’t work out, consider selling it as damaged to a repair shop—they'll likely take it for parts.
It’s likely your motherboard is bricked, which shows why turning off the computer during an update is a big no-no. Some motherboards do have a BIOS flashback feature for situations like this, so look into that if yours supports it. At worst, you may need a new BIOS chip or even a full motherboard replacement.
If the previous method of disconnecting the battery doesn’t work, try downloading the latest BIOS update from your laptop's official site. Extract it and place it on a FAT32 formatted USB drive. Connect your laptop to power, plug in the USB, turn it on, and let it sit for about three minutes. It should begin the BIOS update automatically.
Try removing all components from your laptop: SSD, HDD, RAM, battery, and the CMOS battery. Leave it for a whole day, and then put everything back together. Sometimes a reset can help.
