Macbook pro A1502 hebernation mode exit

BIOS/UEFI Modding BIOS Modding Requests

Hello everyone,

I have a macbook pro A1502 820-3476 which had a Sierra High OS, after formatting it under Windows 10 it became very slow, I decided to return it as before, the formatting went well but the charging of my macbook was interrupted then I turned it on to continue the installation of mac Sierra high OS and it finished well; but after turning it off and on again, it doesn’t turn on .
after a search on the net, I found that the macbook has entered hebernation mode which is popular on macbook 2010 to 2014.

I would be grateful if anyone could help me resolve this issue if it is coming from the bios.

Presumably the SMC/NVRAM reset was already made and didn’t change anything.
There’re some Mac models that we shouldn’t direct install modern UEFI windows OS, outside of the bootcamp, as it makes some strange modifications on the MAC EFI FW… but i can’t help more on this, i’m just passing a little of what i read in Mac forums, you should place this question in Mac Rumors forum or InsanelyMac, i think you’ll get more help there on this issue.

EDIT: Sure of course you should wait for other users pov, i wasn’t “kicking” you out… :innocent:
Good luck, all the best.
