and to avoid enter the safe mood restart your computer and keep clicking on the command + C while booting .

hope this solve the problem.

do you know @Josh Aarons this a logic board of macbook unibody 2.0 ghz without backlit keyboard in the pictures and ricca wants the pinouts of macbook pro mid 2010.

if you take a look at the question I posted you'll see a picture and I explain it. Not sure if your board looks the same as mine but usually they are larger than the other and looks like silver pads.

Most likely it's the logic board. The damage is where the keyboard connects to the board.

Temp solution is when powering on press another key and hold it.

You can then use a usb keyboard!

Here are pictures of me starting my mid 2010 MacBook Pro from the logic board. http://db.tt/lXy8z3GJ. Please be careful. They are near the keyboard flex ribbon. If it doesn't work with the battery plugged in unplug battery connector and plug only Into AC power. My model has this problem because of water damage that seems to have affected the relationship between power button and battery. If at any point after starting up you can use your power button , perform an SMC reset. Hope this helps.

I too had a spill on my laptop causing a few letters to not work or randomly press themselves. I purchased an external keyboard with a built in trackpad.

I was able to disable my trackpad and most of the keyboard keys by doing the following:

1. Go into System Preferences

2. Select Universal Access

3. Click Mouse & Trackpad

4. Turn Mouse keys on

5. I enable "Press option key 5 times to turn Mouse Keys on or off"

6. Click ignore trackpad when mouse keys is on

Doing the above turned off most of the letter keys but still allowed the music control keys at the top of my keyboard to still work.

My logic board is different [ I've also experienced dead keyboard ].

On my board, these pins was covered with protective insulant, so I have to scratch it.

But it didn't start. I have to reset also SMC ( system managment console )

Resetting the System Management Controller (SMC)

If bottom case is removed,you can alternately reset SMC by disconnecting both power adapter and main battery, and holding down power button for 5 seconds.

It can be the Keyboard assembly, or the flex cable between the keyboard and the mother board.

1. You can check the flex cable where is bending 180 degrees and see if there is any sign of breaking.

2.check if you insert the flex cable in the correct way in to the keyboard assembly.

3.If you want to be 100% sure that the computer is working without the keyboard you can strap this 2 pins (picture attached) and you laptop it should be starting.

I'm having a similar issue, where my shift key was always being registered as pressed. I replaced my keyboard and everything worked properly for about two weeks before the problem came back. I now have Karabiner installed, but I'd prefer to find a more permanent solution. Is it possible that reflowing the solder on my logic board could help (this worked when I had the black screen of death)? Thanks!!
