That way, when the computer wakes from sleep, it restores all open documents/applications in the state they were in when sleep started. If you're using 10.9 or later (is that right? Or was it 10.8?), and the MBP went to sleep before the spilling crisis, it would have saved the file to the disk in "preservation of state" mode. If that doesn't work, the next step is to replace the RAM - preferably with sticks that you've seen working in another computer, so you can be sure they're good. Then reinstall, reassemble and reboot, and see if anything changes. I like to use a pink pencil eraser to rub the RAM contacts clean of scuzz, and use a soft, dry toothbrush to brush the rubber crumbs off the RAM contacts and clean the inside of the RAM socket. The process for installing/removing RAM on the earlier A1181 Core Duo MacBook is identical. The first thing to try is to reseat the RAM correctly: Have you been playing arond with RAM recently, or has the computer gotten knocked around? Intel-based Mac Power On Self Test RAM error codes When the computer has a RAM issue (like the RAM's failed, or the computer can't detect it, or it can detect it but it's an incompatible type), hitting the power button causes one or more beeps, sometimes accompanied by a blinking sleeplight: If it eventually chimes or beeps then you can start reconnecting components, knowing that once you connect something and stops working then you have found the failure.It sounds like something's going on with your RAM. If this is the case then you can try disconnecting components (hard drive, optical drive, display, etc) and then powering on again. This tells us that it's not progressing past the early stages of the boot process. Press the power button to turn on the Macģ) If you remove both RAM DIMMs and attempt to power on the Mac does it beep (different from the normal chime) at all or is it just a black screen with with only the fan spinning? If the Mac doesn't beep then it's failing to recognize that no RAM is installed, which it checks during it's boot process.Release the power button and all of the keys at the same time.Hold the (left) Shift, Control and Option keys and press the power button for 3-5 seconds.Connect your power adapter to your computer and ensure that your Mac is turned off.You can do this using the following steps, you might see the power adapters LED change color during the process. A lot of odd issues can come back to a faulty SMC state, which are often resolved by resetting it. This would be my approach to the problem.ġ) I would attempt to remove the RAM and inspect the RAM slots on the logic board, using compressed air and/or a small pick if debris is visible.Ģ) Reset the SMC. My first thought with this would be faulty RAM or possible debris in the RAM slots on the logic board.
