I had some water problems. I could not start my MBP, but I managed to start it with resetting the SMC, doing the following: 1. Remove the power line for 5 secs 2. Attach the power line again 3. Press shift-ctrl-alt-power. 4. After 5 secs the MBP powers up My problems are the following: 1. If I shutdown my MBP, I have to redo the steps above. Meaning that I cannot use it without power supply. Because: - if I don't do step 1, the MBP starts up with full fan and shows no battery in osx. So my guess is that it cannot communicate with the SMC. - if I don't do step 2, the MBP starts up for 1 second and then shuts down. - if I do both steps, the MBP starts with normal fan and I can see the battery normally. 2. My MBP suddenly shuts down while working. Sometimes I can work for a whole night and sometimes it suddenly shuts down. Sometimes it politely asks whether I want to shut down, but I cannot click cancel fast enough. 3. I cannot put my MBP to sleep, it will not restart 4. Probably unrelated, but I just mention it: my volume down key hangs. So apparently there's still some liquid in the keyboard. My assumption: - Somehow the SMC does not receive power while the computer is not running. - I guess detaching the power line shuts down the SMC and then re-attatch it with SMC reset, will power it up again. - I guess when my MBP goes to sleep, also the SMC does not get power and shuts down the computer. I read several posts (http://forums.macrumors.com/showthread.php?t=1713315) and (http://forums.macrumors.com/showthread.php?t=1713315) that it might be caused by corrosion around the SMC. Questions: - Are my assumptions right? - Might any liquid in the keyboard cause a short-circuit that affects the SMC power? I assume the keyboard always receives some power to detect whether a key is pressed, even when the computer is turned off? - Might any liquid in the keyboard cause something like a "request shutdown" key-press? - Where can I find the SMC? I have a MBP8.1 Thanks in advance!
