Keyboard input is randomly interpreted as uppercase during preboot authentication on Vostro 270s UEFI

Hello again

We bought 15 new PC Dell Vostro 270s with preinstalled Windows 8 x64 OS. When I installed EEPC 7.0.2 in UEFI mode on this computers I experienced strange issue with keyboard key map within pre-boot. When entering username, characters are randomly interpreted as uppercase, lowercase or special sign $, %, ^ etc. instead numbers. For example when typing small characters everything is ok, but when I type only one upper case (with shift key) from now all sign is upper case. When I type "a" displayed "A", "&" sign instead "7" etc. I tried CAPS LOCK off, used external keyboard, disable Secure Boot and nothing help. It is very difficult to enter correct password. What I can do now? We have latest versions of all McAffe modules (attachment) and UEFI version (A10). Now Dell doesn't have newer BIOS revision on your page.

Hi Newag,

Same behavior here. Not sure if on the exact same infrastructure / environment yet, but will find out.

Did you manage to get a solution?

Thanks,

probably related to a buggy Keyboard driver in the uEFI - http://kc.mcafee.com/corporate/index?page=content&id=KB79297&actp=search&viewlocale=en_US&searchid=1...
