So I spilled water on my MacBook pro about a year ago. I did the recommended steps to recover it, and everything works perfectly except that it requires charge from the wall to function (i.e. it shuts down if the power block disconnects). I have used it for the past year and had no additional problems, but have recently realized that I would love to have the portability back. I had the computer diagnosed at micro tech, and they told me there is $1500 worth of water/corrosion damage (battery, ram, memory, mother board, hard drive) and that I should buy a new computer. My logic tells me that a new battery might remedy this situation, but the tech guy said I was crazy for even considering this. The components, less the battery, have worked flawlessly for over a year so I don't know why I would invest to fix them all now when it seems that the problem lies with the battery. I was hoping someone could give me some advice as to how to go about this situation. Specifically, is it realistic to swap out the battery to gain back the portable function without risking the functioning of all the other parts that seem to be in working order as of now? Thanks for any help!
