Re: macbook pro A1425 emc 2557 bios request

Finally I think is working but not clear what was the issue!.
I just entered with command +S , hear the chime then waited some seconds (seeing nothing at all as always) and typed reboot not even knowing that something would do... then i saw a folder blinking, then restarted again with option pressed and saw the options, now im installing high sierra on the previously disconnected ssd.
So very sorry for this thread with unclear aspects, shame on me but thats what happened so far,,, thanks to all of you.

bad news... same thing again... but it allowed me yesterday full install of high sierra, after updates in the morning, all back to chime no image ...
when it worked with macosit was very low opening launchpad for eg. (like the animation would be at 0.0003fps) but normal menues were fast.

im with no clues for this case

CHIMES OK
BACKLIGHT OK
NO IMAGE
LOW BATTERY NDICATOR perfect (in case of it should appear)
