Hi, I am looking for help with my Sony Duo 13 (SVD1321M2E). It was working ok until today. Now every time I tried to start, it came up with the message "System Firmware is Invliad" at the top left corner of the screen and refused to start. I have tried the ASSIST button with the same result, so I cannot even get into the BIOS or boot from an external device. Essentially I cannot use the laptop at all. Any help will be highly appreciated.
