2 MacBook giving beep code every 5 seconds when bottom cover is on
I have a Macbook Pro Late 2011 that I replaced display on and upgraded the RAM with PC3 10600 tested it out and did PRAM before putting the bottom cover back on booted no issues. But once I put the bottom lid on, it’ll work for bit then when I turn it back on again it beeps every 5 seconds. When I take the coveroff no issues. I then took the battery out and put the bottm cover back on and had no issues with it turning on and haven’t gotten the beep code again. Is that normal for a battery to do that? Could it be the display? Or something lese?
