I am trying to disable secure boot on my linux mint acer aspire 5 laptop, but the problem is on Security and Boot menu in BIOS up and down arrow keys are not working therefore unable to select Secure Boot to disabled, but Up and Down Arrow keys work perfectly fine in other BIOS menu such as Information, Advanced, Power, and Exit any ideas?

Thanks!
