Hi, I just change my logicboard for my MacBook Pro and when plugin power. Screen blank and keep beeping very softly every seconds. I have removed RAM and try single RAM on both slot still the same. Appreciate your help. Thanks.
Is the system up and running? Or stuck in a boot loop condition? Review this If your Mac beeps during startup Please clarify what the beep code is, you may have either have a bad logic board or RAM.
