Keyboard issue only on boot, works fine after (solved)

[ChrisC17]

Hi,

When I start the pc, I can access to the bios with F10 for exemple, but after that, the keyboard doesn't work and I can't navigate along the differents menu with the arrows key and the function keys, Esc, Enter don't work.

After booting again, I can use F9 to access the boot manager, but I can't navigate in the menu.

The keyboard works fine on Windows.

In the bios, if I plug an other keyboard, it works fine.

Hope my english is good enough to be understood, thanks for your time

I did a reset of the bios, loading the default settings with F9 :

- after rebooting and entering the bios with F10, no change, the keyboard was unusable

- I pluged an other keyboard and disabled the Secure Boot and after booting everything is ok with the laptop keyboard

- With the laptop keyboard I enabled once again the Secure Boot and after the reboot the laptop keyboard is still ok to access the bios and navigating in it.

So, everything is ok... Thanks for reading. Chris
