Hello Sir, i have one answer.
5 monhts ago i sent here bios on unpass. All good, bios works without password but after 3 months customer was back a he said me he have bios password again. I used unpass bios again, updated on newest version on with my clear windows test SSD a after few days he was back a bios is now still in computer. Have you some expriences with this problem? Have this motherboard supervisor pass? Could it do some software with Microsoft office accout? Now i have no ideas, Thanks.
