My gut feeling is that most likely the board is bad - often expansion and contraction of a board due to heat will cause it to power on when it's cool, but then shut off when it heats up and flexes. Looks like you've done a pretty thorough job. I plugged it in and attempted to turn it on and it came right on. It tries to spin-up but it then cuts off before the screen ever illuminates. I have now unplugged the charger and continue to use it and it has not yet shut off.ĮDIT: To further troubleshoot this I turned it off and attempted to turn it back on with the charger out (battery now indicated to be at 6/8) and it does not turn on. I plugged in the charger, pressed the power button once more and it turned on and has remained on.

Boom, the Macbook began to power on, however at one point during the grey load screen it shut itself off again. When this did not work, I disconnected the battery and charger, pressed and held the power button for 10 seconds, reconnected the battery and pressed the power button. I then removed the back and tried to power on the Macbook by the two silver jumper pins on the logic board to no avail. I pressed the battery indicator button and it showed it to be at 7/8 charge.įirst thing I did was look up the specs to accurately trouble shoot. This happened whether the Macbook is plugged in or not. When I pressed the power button nothing happened no fans, no HDD spin-up, no LED's, nothing. It came in because it would periodically turn itself off, and would no longer turn on. The Macbook I'm working on is a A1297 EMC: 2329 2.8Ghz model running OS X 10.7.5.

Any suggestions on other forums to join would be great too. I'm working on this Macbook and since I am none too familiar with Mac (I'm a PC Guy) I joined this community to learn more. Hello everyone, I just registered and I'm glad to be here.
