What logic boards from other models will most closely match A1229?
I have a 2007 2.4 GHz MacBook Pro (A1229) with 4 GB of RAM.
My power adapter recently started acting up and it unfortunately caused a power surge of some sort and now my laptop does not power on or make a sound at all when using the power button. I tried shorting the power button, with no luck. I then removed the logic board after testing the input voltages coming from the I/O board (16.5v). This was after repairing the MagSafe charger.
I plugged the logic board and felt for hot spots after letting it sit for a few minutes. I almost instantly found an extremely hot spot. It seemed to be coming from a very small capacitor near the power I/C. I gave the chip and capacitor a little nudge with my finger and POOF!...glowing red power I/C and smoke everywhere. I immediately unplugged the board before the logic board itself was damaged. I don't believe a simple nudge should have caused a good chip to do that!
After looking at the schematic, I believe the chip is ISL6269bcrz or something of the sort. It is a very small square chip with 7 pins on all 4 sides.
Could the capacitor that I thought the heat was coming from have been the problem or both? How many more components in that area may have been damaged?
I have been looking for an exact match for the logic board on ebay for less than $15, but I can only find boards from around the same time period and for 15" models. Where most Macbook and Macbook Pro models made using the same components for the power circuit?
I could order the chip on its own for $5 but it would be nice to have a logic board that contains multiple spare parts in case of future failure. I have no experience soldering chips, especially ones of this size, but the proper equipment is on its way and so is a brand new unbuilt gaming PC (goodbye Apple), well Apple hardware that is...
The capacitor that was extremely hot is the one directly above the top right corner in the first and second images, right underneath the H-bridge.
Is this a good question?
