Keyboard shorted?

[stynger007]

Hi everyone, new to here , long time lurker

I have a 2010 MBP 15.4 inch ,2.4 ghz 4gb ram, 320 GB hdd

A minor water spill on the keyboard was dried,and worked fine.About a month later,the macbook began a rebooting loop. Pressing the power button didn`t always work. I found that by disconnecting the ribbon cable to the keyboard,the machine booted fine,mouse and trackpad all good.As soon as i reconnected the keyboard,a message asking if I was sure i wanted to shut down,restart,cancel or sleep the computer, would continually pop up. Fresh install of Snow Leopard 10.6.8

Sounds like there is a short in the circuitry of the keyboard, specifically related to the power button.As mentioned the unit boots perfect without the keyboard connected. I do not have a USB keyboard available.

The logic board is clean , free of corrosion or stains. Removed the keyboard (it`s a unibody) all 71 screws- a few had rust on them.

I have ordered a keyboard hoping that it is just a keyboard problem.

Has anyone else had something similar happen , or if anyone could chime in their opinions that would be appreciated.

Thanks in advance!

You may have luck, but the logic board connector may be what is shorted. Just because you don't see the corrosion doesn't mean it isn't there.

Thanks for the reply and the tip..There is no visible corrosion at all , will clean it regardless, hopefully the new keyboard will solve the problem...
