Lenovo W540 BIOS repair and password [HELP]
Hi at all,

i got a W540 with a broken BIOS, after pressing the button, one beep and nothing further happend!
I tried to repair the BIOS according to this video :
After flashing the both files into the Eproms, the W540 startet again, but the following messages appeared on the screen:
0271: Real Time Clock Error - check Date and Time settings
0183: Bad CRC of Security Settings in EFI variable

The first message I think would be not the problem, but the second !?!

The next problem: I can not access to the BIOS because of an unknown password !

Can anyone help me with this problemĀ  - the unrepaird bios filse are here:

thanks a lot
