The only keys that seems to work are CTRL ALT DEL as it restarts the laptop and CAPS LOCK, FN keys.
As as computer user, you’ve probably heard of the BIOS by now, which stands for Basic Input/Output System.
Feel free to let us know what you think in the comments.
The main purpose of the BIOS is to check all the hardware components attached to the computer and then to load the software on a boot device (hard disk or CD/DVD). The BIOS will check for all hardware components like hard disk drives, CPUs, RAM, graphics cards, keyboards, mice, optical disk drives, and other hardware. Mainly, you can use it to configure the hardware on your computer.
And be noted that the USB flash drive or hard drive must use FAT32/16/12 file system.
Because BIOS flashing is potentially risky, if you do not encounter problems using the current version of BIOS, it is recommended that you not flash the BIOS. Inadequate BIOS flashing may result in system malfunction.
