MBP dead after being smashed on the keyboard.

I have a Macbook Pro A1150 which is now a brick after being smashed on the keyboard/trackpad when I dropped a maglight on it. It instantly went black, and hasn't shown any signs of life since. Even the charge light is out.

I imagined that the logic board was probably cracked, but I just removed the upper case and I can't see any obvious damage.

Anybody have a guess what part is most likely to have been damaged? I'm not sure where to start.

Is this a good question?

I put the upper case back on again. Now the charge light shows orange. Unfortunately, the battery lights don't show any charging. I left it a few hours and then tried to power it up. No luck.

A somewhat more careful examination of the battery lights revealed that briefly after the AC adapter is connected the battery indicates charging. These lights then fade to blank.

"very interesting", what do you think it means?

by

My guess is that the signal that the AC has been attached is getting to the battery, but no actual charging current is getting through. Thus the battery briefly lights up until it depletes its surface charge and then goes dim again.

This suggests that *at least* the left IO board is dead.

Took it to the genius bar today. They stuck in a better battery. No effect. He took it in back and reseated the memory (already tried that). No effect.

Apple offers a $310 + tax flat-rate repair service assuming there is no obvious mechanical damage (at which point the price goes up) but I didn't see any when I opened it.

Boy, Apple is awfully good at finding price points, this is almost exactly slightly more than I was hoping I was gonna wind up spending on this thing.

CHIME!

Not saying Mayer is wrong but a couple things worth a try

  1. Disconnect keyboard completely. Inspect connectors. Restart with keyboard disconnected.
  2. Try powering up without the battery installed If it boots, replace battery connector cable.
  3. Reset the power manager.

Resetting the Power Manager (SMC)

Disconnect the power adapter and remove the main battery.

Hold the power button down for five seconds, then release.

Install the main battery and connect the power adapter.

Press the power button to restart the computer.

There is a whole page of troubleshooting in the manual that may assist you to progress further

+ why not. I'd also try an external keyboard. Put the hard drive and optical drives in external cases.

I agree with Richdave, since the top case may be damaged by the impact I would remove it and try to power up the machine directly from the logic board.

by

I will try booting it with the keyboard disconnected. I will need the upper case cabled though so that the power button will work? I'll look into how to disconnect just the keyboard and trackpad, but leave the power button functional.

Unless you have an identical MacBook to switch parts with to test them, this sounds like a job for a professional who has the tools. Pros do have their place.

Aww, come on, anyone willing to conjecture?

This was an impact right in the center of the upper case. Directly below this is the keyboard/trackboard board, the battery and the logic board. So it's got to be one of these, no? It seems unlikely that something peripheral was damaged.

Admittedly, if the disk drive was active it could have caused a head-crash, but then the machine would get as far as trying to load the OS before it failed?

What would cause the machine to show no life at all?

Would damage to the battery be sufficient? Would damage to the keyboard/trackpad be sufficient? Or does this have to be a damaged logic board?

I need to figure out if it's worth putting any effort into this machine at all.

Denial. Your in denial. I am a pro and I really wouldn't want to mess with this one. Maybe someone else will chime in and give you a naive encouraging answer, but not me ;-)

I actually keep a second Mac around for just the purpose stated. Both my machines. I fixed a display issue the other night with the spare Mac. Both are identical. The display on my main one was turning strange colors, so I swapped screens and guess what .. problem solved. Then I tinkered around with the cables on the bad screen and something was loose on that connector on the bottom which says "do not touch!" in large letter. Guess the previous owner touched it the wrong way but it works now too :)

Mayer, check EVERY ribbon cable in that thing. I bought one that was doing the same thing off Ebay for a hundred bucks and several of the ribbon cables were loose. When I checked them all and reseated them, it worked fine. It's now my second and testing computer ... I use it to test parts I might want to put on this one so if anything goes wrong, I don't mess up my main computer. Also could be a hairline crack on the logic board causing problems. You can't really see those very well but they might sever a connection on the printed circuit board also causing problems. I'd probably get on Ebay and buy a logic board off there to replace it.

Sounds like you are confirming what was previously stated. Check the cables (Richdave), if that doesn't work, replace parts with known good ones (Mayer). I look forward to your next 8,000+ answers to see how you square up to Mayer. He's getting up there in age ;) and we need another one like him.

I am, and I do work on computers professionally. I've had this kind of things happen on my machines a few times. More often than not there's only three or four things outside of burned out chips on the board of something like that which will cause a dead machine. Fixing them is definitely a pain in the butt too, or expensive if your hire someone else. I do computer repair, free lance photojournalism and am a musician. I own both PCs and Macs.
