MBP behaving very strangely after spill damage - want to understand!
So I followed the repair guide on ifixit to take apart and clean my MBP 15'' 2010 model after a liquid spill on the keyboard and top case. I left it several days and then tried to see if I could get it working. The result has left me with a semi-working computer but I have a few questions about the strange behaviour I have seen. I really hope somebody can answer them.
I took out the battery and with every cable removed, I looked if I could get any response when I plugged in the charger. The green light came on with nothing plugged into the logic board. I slowly plugged everything back in, and found that it was only when the keyboard itself was plugged into the logic board that the computer would not turn on. Question 1: Why is this? Does one shorted or damaged piece of hardware stop all function on logic board?
At the moment I am using my computer with an external keyboard, and powering on and off simply by plugging in the magsafe, which fortunately somehow seems to boot the system straight up. Question 2: I would like to ask, if anyone knows, why this happens?
Without the power button, I have no control over the computer powering on and off, and sometimes the green light on the charger merely flashes on and off, until suddenly it seems to boot okay and the fans whir into motion. Question 3: Why is this happening? Is this at all worrying?
At this stage, I think I am merely going to replace my upper case and my battery. From any of the behaviour described above, please let me know if you think there is more work to be done (i.e. replacing magsafe power or something)
Many many thanks to ifixit and anyone with time or mind to respond.
Is this a good question?
