Logic Board repair

[adamradam]

I own a Apple MacBook Pro "Core i7" 2.2 15" Late 2011 that has had the logic board damaged near to the left of the ram slot.

In the picture I attached I have circled where I believe the damage is. I'm not sure if this is a resistor or what.

though it seems to be missing on my logic board after someone replaced the ram and now the HDD is not being read.

Any help would be appreciated !!!!No code has to be inserted here.

What sort of help are you looking for? Are you looking for logic board repair help? If so...I'm afraid only seriously skilled folks usually do this. And by "serious"...I mean depot repair employees with access to seriously expensive equipment (and this is if the logic board repair makes financial sense).

You may want to look into Apple flat rate repair service for this. The cost may still be worth it on a 2011 15" MBP.

Nick,

I want to replace this part that is located in the picture attached in original post. I have someone capable of doing the repair, but I figured I would find out on my own first what i'm dealing with. To my belief it is a resistor so i would need to know the specs.

Regards,
Adam

Are you sure a part is missing? Without a schematic or service manual, you're going to be hard pressed to find out if anything is missing or if that's the original design layout. I find it hard to believe someone could have removed anything from the logic board just from replacing memory modules or the hard drive. You may be able to get a view of the logic board by going to the ifixit web site and look up the take apart procedures for your particular MacBook Pro. www.ifixit.com

And if you're thinking about digging up an Apple schematic or service manual; good luck. Apple keeps that stuff locked up like gold at Fort Knox.

I'm 99% sure its missing or damaged. I found high res pictures and compared to mine with magnifying glass and its very clear that it was damaged and removed. I tried find schematics, but like you said difficult had no luck.

Just a head up I believe I found my answer on another forum site. I was told it's reference designator FL4501 which is a 12 Ohm 100mA-8.5GhZ common mode filter. This particular one is a TDK made TCM0806-4SM.

Good news. But it makes me wonder why someone would remove that particular component unless it was damaged by a short? And by the way, that's not a normal resistor but actually a high frequency filter.

Looking at where the filter is missing (close to the Ram Clips) maybe someone got rough taking out the RAM and broke the part off the board. I have seen it all including a person brushing the Logic board HARD with a toothbrush and Alcohol and tearing off many surface mounted parts!!!

If this is true. Please give us an update how things went (good or bad).
