Hello,
Have you tried using an external keyboard, and/or removing and replacing the
CMOS RTC backup battery to see if that makes any difference?

Hi folks, long time no type.
I recently bought myself a new Ideapad Z580, and while I know that
Ideapads are not Thinkpads, I was hoping that someone here may be
able to help before I have to send the thing back to Lenovo for service.
This machine came with Windows 8 preinstalled, along with a
new-fangled UEFI BIOS, and it appears that all is not well. UEFI
includes the new Secure Boot technology which is designed to prevent
booting other operating systems or external media, and unfortunately
it's doing that too well. I've managed to screw up the OS and I
want to restore from my True Image backup, but whenever I try to
boot from the True Image CD - or any external media, for that matter
- I get a Secure Boot ACCESS DENIED message, and my only option is
to continue to boot Win8 from the HD.
Simple, you might think - just enter the BIOS and turn off Secure
Boot. Aha, but there's the rub! I can't enter the BIOS, nor can I
bring up a Boot Menu. Neither the F2/F12 hot keys, nor the Win8
menu option to enter the BIOS, works - they simply cause the boot
process to pause on a blank screen for a couple of seconds before it
proceeds into Win8 again.
I'm pretty sure this is going to have to go back to Lenovo to be
reflashed, but I thought I'd ask in case anyone knows of a hidden
key sequence or other means to force entry to a UEFI BIOS. I have
read of a similar problem from a Dell user, but apparently the Dell
BIOS "ACCESS DENIED* message gives an option to disable Secure Boot
and try again, but the Lenovo message does not. There is no user or
supervisor password set, nor am I even getting as far as being
prompted for a password even if there was one.
Thanks in advance, and Happy Thanksgiving!
Cheers,
Jon.
