Keyboard keys do not work

[ali20142014]

I was trying to disable driver signature. After restarting the computer, I cannot press F7 to disable as the keys on the keybord do not work.

I cannot also press Del or F11 to enter the BIOS and choose BOOT methods as well.

Once the computer is finished booting, the keyboard works fine.

Why it does not work before booting?

It is a USB keyboard.

Turn on Legacy devices in the BIOS...

But i cannot enter bios as the keyboard led light is on after i get the screen where to say to enter bios.

Or it might be the keyboard itself. I also have USB keyboard and some of my letter keys didn't work,in the end found out it was the keybard itself. Try checking with another keyboard it the same keys ain't working on that one too.

i solved it. it was fastboot on bios

I thought you stated you couldn't enter BIOS...

i disable fastboot by pressing power button continuously. it will shut down your computer after turning on. then turn on again it works.
