Randomly shuts down when not connected to an external display.
Text:
Hi, this is my first post on ifixit so bare with me.
About a couple of months ago i was away from home and my Macbook randomly shut itself down. It kept on doing this so i did a bit of googling and thought it may of been the heatsink not keeping the CPU cool enough so it went into protect mode and shut down. I took my mac apart and saw that the heatsink wasn't looking too great so i decided to change it just incase that was the problem.
After fitting the new heat sink the problem went away. Since then I've been using my macbook pro as a desktop. Connected to an external display with a keyboard and mouse. The problem hasn't been happening. Great! Or so i thought until the other evening when i removed my laptop from my desk and tried using it elsewhere.
I've troubleshooted the SMC, reinstalled OSX, tried it in safe mode (Which worked), tried a new user account, disconnected everything one by one to see whether something triggers it... Nothing but disconnecting the external display seems to trigger it to happen.
So in brief. My macbook will only run for about 10 seconds without an external display before the screen goes black and the keyboard lights and fans stay on then turns off.
Please help if you can.
