Answer to: replaced logic board,doesn't boot keyboard doesn't workDid you replace it or was it replaced by someone else? If possible, it would be great to get pictures of the logic board as it sits as it may be true that some components are not connected. However, if it was replaced by Apple under the GPU recall, I would definitely leave it as it is and bring it back while it still has these issues, and they will (at least should) replace it for you under warranty (I believe they have 3 month warranty on these recalls). Please keep us updated so we can help you out! Thanks!
Answer to: Serious software problems about the battery.On the software side, the best thing to do would be to upgrade to the latest OS if you are not currently on it. However, from what you have described I do believe it is hardware based and requires a battery replacement. No matter the amount of resets or calibrating you attempt to do, if it is a bad battery the problem will not go away. Many software programs such as coconut battery, etc, are very good at determining whether the battery is bad or not, but there is no program that can determine the condition 100% of the time. For testing purposes, if you are comfortable with it I would suggest opening the backplate and disconnecting the battery, and then put the computer to sleep while it is plugged in with the charger to keep it alive. If the issue continues to occur, you can confer that it is not the battery that has the issue. If the computer had told you the battery requires service months ago, it is even more reason for me to believe your battery is bad. Depending on how comfortable you are with fixing Mac...
Answer to: It appears that my batteries have bulgedPersonally, I think you will be able to do this repair yourself. However, I would advise against a heat gun unless you are absolutely sure you know what you are doing in regards to how long you heat it, etc. I use an old credit card or something close to it that is sturdy but thin, and very carefully peel off the parts of the battery, starting from the outside and working in. Be careful not to gouge or push in any part underneath the battery, especially near the trackpad. As each part begins to un-adhere, it will get easier. As always, unplug the battery and discharge the case beforehand, and be especially careful to take your time, if you work hard and respect your product it will save you a lot of money.
