How to fix the problem ” can’t enter the bios”

I am using the w530 k1000m. I was not able to enter bios. I tried to press F1 and F12, both leaded to black screen. I can not upgrade and refresh the bios. Because there was no newer bios version available. I hope to reset the bios.

a.  Download and extract the BIOS update for your system from website.  Do not choose to install the BIOS update yet

b.  Open command prompt as admin user

c.  Change to the extracted BIOS folder (e.g. c:\drivers\flash\xxx)

d.  “winflash64.exe -patch -cvar”

e.  The system will automatically reboot

f.   You will see an error like “bad CRC of EFI variable”   (this is normal)  Press F1 to enter Setup

g.  Change to the “restart” page

h.  Set OS Optimized Defaults to “Enabled” (if you are running Win8) or “Disabled” (if you are running Win7)

i.   Press F9 to load setup defaults

j.  Press F10 to save and exit
