Sony Vaio Z70CR S1204-2 48.4MR05.021 mbx-267 Good afternoon, my friend. I have a problem. I made a bios update on sony vaio sve171c11m when updating the out monitor and nothing happened, I waited 15 minutes but there were no reactions, I tried to turn off the laptop from the button but the laptop did not turn off, I had to pull out the battery. I ran the main Bios without problems but the EC Bios does not pass the verification. Can you help me? Please
