I have GRX560
After the BIOS update the laptop rebooted. The screen is blank, the HD and CD checks ( they spin for a few sec). The floppy (USB) is not detected. NO MESSAGES OR BEEPS.
It is just DEAD.
Tried to boot form CD, did not work.
I did not see any errors while the update. Sony claims that the problem is caused by me and is not covered by the warranty.
Is there any way to recover??????
