My advice may not work for you, and I don't take responsibility for any damage on your device,

BTW is not recommended to dig in to bios and make changes, unless you know and are aware of what can happen :D 

Blint bios reset > : 

1 power off your obook

2 plug otg with usb keyboard/ the magnetic one doesn't work well in bios/efi

3 power on your obook and press few times ESC

4 now we assume and hope that we are in bios

5 press 5x arrow down 

6 hit enter ( to enter main bios setting )

7 hit F9 ( load option default )

8 hit ENTER ( confirm yes ) and prey ;)

hope this will work, if not, please don't quote this post more and more... send me personal message instead so we don't have hundred spams for one question.



Please hit the THANKS button if I helped you! Thanks smile.gif
