Hello,
I flashed Bios mod: LENOVO_Z500_P500_71CN51WW_NWL_ADV to my Lenovo P500. During the procedure it gave the following error and stated to press enter to continue, which I did. Then it proceed to flash the bios anyway. My bios is now showing all hidden options, but I have lost my embedded Windows 8 Home key. What can I do to get the key back?
Error 28: Protected Range Registers are currently set by BIOS, preventing flash access.
Please contact the target system BIOS vendor for an option to disable Protected Range Registers.
