If you want to fix it, you have to identify where the problem comes from?
ihave 820-00293-a
bios password lock
after ulock ssd not show
itry onther bios ssd show but slow start up and frez
but orginal file all work fine but ssd not show
the unlock has nothing to do with the drive.
have you tried adding another BIOS?
you must move me region from old bios to new bios and it will boot quick
Can move region to new bios
but BIOS you send is Original. This is only suitable if you have used a non-native BIOS.
this is orginal but password on bios
then I unlocked it for you above, do not know how to try another BIOS?
If you do not know how to fix it, I recommend that you bring your macbook to a professional store for further assistance.
