MacBookPro 13" Retina beeping 3 times a1425
I bought a second hand macbook pro retina 13". It looks like great, but if i want to start, it is beeping 3 times. It was water damaged, but I try everithing. Pcb cleaner, heating, but just beep, beep, beep..
The dc-built in adapter was not damaged, just the mainboard water indicator what is red, and its charging
Can i change the ram modules, or reball?
Somebody met with this problem whit this mac?
Is this a good question?
