Dear folks,
Recently i experienced some complicated issues with my Macbook pro 13" late "11.
Problems started with a complete dead laptop. Not willing to start-up. Performed the official advised steps to check what kind of problem it could be. Nothing worked, complete dead laptop.
However, after several days i tried again and the laptop gave a different respons when starting up. Instead of staying completly dead it gave me a 3-beep sound at start-up which indicates RAM issues if im correct. I swapped the RAM's and tried them one by one. Eventually even tried identical ones from another mac pro but problem stayed the same.
To make things more complicated a few days later when trying to reboot the laptop it worked fine for half a day untill the problem returned. At this moment 50% of the time it is not booting and giving me the 3-beep sound on a black screen. Th other 50% of th time it gives me a start up chime and it looks to working fine for some minutes! Varying after 10sec. - 2min. it will show strange patterns in the screen and eventually it will reboot.
I start to worry it might be a faulty logic board?
Advise please!
