BIOS version problem my device is
Lenovo ideapad s540-15IWL GTX after recent bios update for version
BWCN19WW
the internal HDD (ST1000LM035-1RK172) , started to fail and this took me months to figure the problem but after searching for alot of time i found that this exact HDD model even in different laptop brands like Asus or Dell with bios updates is failing and i mean by failing that you suddenly find your laptop restarts and then the hard disk is not even detected in the system anymore at all and even in the disk management its only detected in bios so i tried to search for older versions on the the support site but they don’t have any older versions or even when i requested old ones so if someone could help
You cannot update your bios to the older version. Wait for new bios update, if it’s cause by bios then update will bring it back
