After water damage, no keyboard and only running without battery.

Some wine was spilled over the keyboard, after few seconds stopped working.

Disassembled, major spill was inside the keyboard. Removed the mobo and cleaned the affected parts near the battery and the dc magsafe board.

Assembled everything back, no luck. After removing the battery, the computer will work normally but still no keyboard. If I place the battery back it won't start.

If I press the battery level button, the battery shows fully charge, and if I plug the magsafe connector will always be green (doesn't change to orange).

So, do you guys think the battery got wrong with the spill, or it will be something in the mobo related to the battery? Is there any way to check the battery¿

The keyboard won't still work at all, do you think a keyboard replacement will do?

Thanks a lot.

So, would be same if I replace keyboard and backlight, and also the battery.

I thought the battery problem could be in any way related to the mainboard since it was showing full charge from the indicator...

Much better this way ;).

Thanks a lot for your answer. Will do the fix and comment.


thanks mayer. I'll do that, will give me time to properly check the battery. Tempted about using my macbook's battery as a replacement but if there was something wrong in the motherboard i guess could damage my batt...

will keep u updated guys.


Well, so at the end I replaced the keyboard and the backlight. Everything worked but the F1 to F9 keys. I removed back cover and reseated the keyboard flex. Working like a charm!

About the battery, I got into a mistake while testing it with the keyboard flex not connected, I didn't know the power button was part of the keyboard circuit.

So thanks a lot for your answers. The macbook is working perfect again!

I'd replace the keyboard first. I use an electric screwdriver to remove the screws, and there are a lot! Part cost $23.00 : http://www.ebay.com/itm/100-NEW-Original...

Then address the battery issue.

You will have to replace the upper case and the battery. This is a long and lengthy procedure on your Mac that could take anywhere from one hour for experienced technicians to three hours for unexperienced fixers. Use this guide (MacBook Unibody Model A1278 Upper Case Replacement) to replace the upper case and this guide (MacBook Unibody Model A1278 Battery Replacement) to replace the battery with the corresponding parts from iFixit. Be very careful with the ribbon cables, since these break really easily.
