No power on after keyboard replacement.

Hi,

I just finished up with replacing the keyboard on my A1286 15 MacBook Pro. Serial no. ending in 7XK.

After doing the keyboard replacement the device doesn't turn on however the MagSafe charging light indicates that it is charging. Any ideas as to what I could be missing? This is my first repair on a MacBook so I'm very new to this...

Thank you!

I manged once to get it to boot by unplugging the battery, holding the power button for ten seconds, then plugging the MagSafe in and continuing to hold the power button for another ten seconds. After which I let go and pressed the power button once.

It worked once but hasn't since then....

You got am spontaneous rebooted by disconnecting the battery and mag-safe then reconnecting.

The first thing to check is the keyboard to logic board connector seating. See step #18 of this guide: MacBook Pro 15" Unibody Mid 2009 Upper Case Replacement

I've just reseated that connection and checked the cable for any snags or marks but still to no avail.

The command key, back space and S key didn’t work.

I take it you spilled something on it?

I bought it second hand, so I'm unsure whether it's been water damaged. I did have a good look inside the device and none of the LCI's are triggered. But who knows. It wasn't stated when I bought it.

sounds like you have a bad connection or missing connection. Go through and double check to make sure all cables are attached to the mother board correctly. did you take out the battery and ac adapter before doing the keyboard? if not it could cause a short on the logic board.

Definitely took out the battery and AC adapter before hand. The MacBook has booted since the keyboard replacement after an SMC reset but since then I haven't been able to boot it up again.

I'll double check over the connections tomorrow morning as it's getting late in the UK... I did do this once before though.
