MBP 13 dead after switching SuperDrive with HDD.

[kosaga]

So I just replaced the SuperDrive with that HDD Sata III Adapter (with the HDD of course) and my MBP doesn´t turn on anymore.
Just a plain blackscreen, the fan does not work and there is no boot sound either.

I already tried to unplug the battery for a several hours and plug it back in. Nothing.
Tried to start with the magsafe and unplugged battery. Nothing.
Also tried a SMC Bypass. The fan is working but nothing else is.

The magsafe lights up in green when I plug it in. With or without connecting the battery.
Although the MBP (13" Early 2011) doesn´t start up I hear a little noise when I´m upclose with my ear on the MBP whenever I press the power button.

Also I should mention that I connected an usb-stick before the first boot after I finished the SuperDrive replacement.
On the first boot (not a SMC Bypass) the fan worked but the screen was black.

Hope that anyone can help me.
Thanks in advance.

Greetings,

Steven

Most likely a cable wasn't reseated properly. Your best bet is repeat the process by starting over.

If reseating all the cables doesn't work, then it is quite possible you damaged something (cable/connector/shorted something/knocked something else loose) during your installation.

Also try without the SSD in at all, possible there is an issue with it keeping it from powering up.

Can´t seem to find anything here. Battery is unplugged on purpose.

I already tried: SuperDrive + SSD, HDD + SSD, Superdrive + HDD, SuperDrive + Nothing


Edit: Found out that the little noise comes from the SSD (SuperDrive + SSD constellation).
When I take the SSD out and press the power button I hear only hear a tiny click or crack.

So, out of curiosity and mainly despair I removed the logic board and looked on the back of it to see, if there are any burned or suspicious areas.
Maybe one of you sees anything...

I did exactly the same thing when i swapped cases on my MBP13. The ribbon cable that plugs in beside the ram slot had to be PERFECT. It took a few goes but that fixed it. I hope in your case it's nothing serious.

 

[kosaga]

Thats the cable for the loudspeaker isn´t it ?
With perfect you mean perfectly fitting into the plug ?

 

[Mnowell69]

It should be the keyboard ribbon, the one where you have to flip the latch.

 

[kosaga]

Tried it several times with no success on booting.
However, I did not touch that keyboard ribbon when switching the HDD with the SuperDrive so I don´t think that is the issue for this problem.
Correct me if I´m wrong.
How does an unplugged keyboard prevent the system from booting anyway ?

An unplugged keyboard means the power switch won't work, but a badly connecting one could cause some crazy symptoms.
If it obviously isn't that then like azentropy said, completely remove the adapter and see if it works again. Otherwise i really couldn't say. Sorry

its possible you didn't take the correct ESD precautions when working on your mac and you've given the logic board a static shock, causing it to fail, did you wear a grounded wrist band ?

 

[kosaga]

I will do the replacement process tomorrow again and try to do it very neatly and correct.

@dannylillhtc In fact I did not take these ESD precautions hence I did not wear a grounded wrist band.
What if I DID give the logicboard a static shock ? Would it be totally damaged ?

 

[dannylillhtc]

I'm no expert in these things i just normally take the precautions due to good habits, its possible you could have damaged a component that is critical to the booting of the system, I'm not sure to be honest

 

[Mnowell69]

sadly a number of things could have happened, with ESD being the most likely. even a faulty SSD adapter might have shorted something.

 

[kosaga]

No way to fix it if it actually happened ? Well other than buying a new logic board of course...

 

[Mnowell69]

the best thing to do now is just connect the display cable, the keyboard cable, the fan and the memory and see if it fires up. Then one at a time connect everything else if it did fire up. This way you know that the board is faulty.

 

[cookiesnfooty]

Sounds to me like the motherboard may have been fried, this could be from ESD or the drive adapter you fitted as I have come across devices that have the potential for causing power surges.

I did this just now and it won't even boot with display, keyboard, fan and memory.

So.. nothing to do here except buying a new logicboard ?

 

[Dead0k]

try some 3rd party advanced apple service to diagnose the issue before buying a new one (if it necessary)

Not sure how that will help if the machine won't boot. OP will need to get hold of a logic board that is guaranteed working.
