Liquid splashes my keyboard


some liquid splashes my keyboard. I have completely unsettled the hardware and let it dry. But I found no liquid trace on the mainboard.

When I had replace the hardware and put the power on, the screen lights on, I heard the sound but a few seconds later its turn off and open again in the same cycle until I remove the power cord.

I'm searching informations to know if is the mainboard is out or is it a keyboard problem?

Thanks for your help.

I've had a similar problem after a liquid spill over the keyboard. Pressing some of the keys created a short circuit, and to power the MBP up I had to disconnect the battery connector and connect it again.

Since there was no liquid on the logic board, I bought a new top case from Apple and installed it. Everything works fine, except the DVD drive, which has no juice at all. I only found out now, weeks later, when trying to burn a disk. Might have made a mistake during reassembly, or the drive might be shot.

I've never heard of a keyboard causing this behavior. It could possibly be corrosion or damage on the rear of the logic board.

Thanks for your comment.

I have this information from SAV who says that a "short circuit in the keyboard" can cause this problem. But I can't verify my self.

In fact I have found nobody to tell me if "when the chime is heard" the motherboard is in a good state.


Mac Intel POST (Power On Self Test) sequence would indicate you have a boot disk problem, or a corrupt version of the OS. So see if you can boot from your installer dvd (a failure doing this probably does mean a logic board problem).



I will try it and leave a comment for the result.


My MAC doesn't start anymore...
