2009 A1286 MacBook Pro not responding to any input?

Hello,

I have what I believe is a Non-Water damaged Mid 2009 MacBook Pro that I recently picked up from eBay.

However when I tried to turn it on, I found something I have seen happen before, which is that the MacBook does not respond to the keyboard at all. So I took off the bottom panel and shorted the power button pins, because that always works for non responsive keyboards, however not only did I find zero damage on the cable or anything else, but shorting the power button pins yielded no response at all. No fanspin, no power to the hdd, no DVD drive noises, just complete silence like the battery was dead or something.

I have tried resetting SMC, but that hasn’t worked because the MacBook does not respond to any activity on the keyboard.

All it does is charge the battery and display how much percentage is left from the built-in battery meter. Any help is appreciated as I’m at a loss as to what is going wrong here.

I also do have a hot-air station, so if there’s any keyboard controller chip that goes bad, I can replace it.

Unfortunately after thoroughly examining and diagnosing the board and finding absolutely nothing that looked wrong or was shorting at all, I have decided that the best course of action is to buy the best compatible motherboard for it (a 3.06ghz T9900 motherboard to be specific). After disassembling it I figured out I actually had been scammed by the seller as well, as the CPU was a 2.66ghz CPU, and not the 2.8ghz CPU that was advertised, not like it mattered though, as the board was completely dead for some unknown reason. I should also mention that I bought this computer as-is specifically to repair, too, so it’s not like the seller was going to accept returns. Anyways, I want to thank everyone that tried to help in this situation, I really, really appreciate it.

I bought it to repair it, so that's why I'm here and not returning it.

What is the onboard battery checker telling you? Do you have four or more LED's lit? If you do then the issue is within the logic board, at this point you’ll either need to debug the logic board circuits to see if you can fix it or just replace it.

At that point I agree with @mayer this will likely cost a bit of change ($60 ~90 for a used logic board if you can find one) to get the working again. I think you should return it to find a better system.

Well the battery I have for it already had alot of charge in it, and it does charge the battery as well. It lights up at about 6 bars, and charges steadily when I have it plugged in. How would you go about debugging it? The seller doesn't accept returns since it was an untested item.

This is not easy! You need the schematics & board views as well as the ability to read and understand them. Then you need to tools and lastly access to the parts. The costs are adding up!I think you should focus on finding a replacement logic board.Review this guide: MacBook Pro 15" Unibody Mid 2009 Logic Board Replacement

I think you'll need to drift over to Louis Rossmann's YouTube channel that should give you an idea what is involved to fix this logic board.

I know how difficult it is, that's why I bought it to repair it as a project to do. I'll try a few more things and report back if anything worked before buying a new logic board. If anyone has any other ideas of what the problem could be, comment it, any help is appreciated.

@visionarily - OK, thats fair, If you had started out in your dialog with that fact I think our dismay would have been less.
