Hello. My Vaio z-flip model laptop has encountered a problem and unfortunately, it turns on, the computer does not display and just displays a black screen on startup. My data is unimportant, and I don't need to recover the media.
The laptop fixer told me " the BIOS file installed on my laptop has been lost with the factory reset. I need the installation BIOS file to boot the laptop system." Is it true?
Please guide me.
