Well, I did an internet search and didn’t find a specific how-to guide on the battery replacement, but I know a lot of people do dig around in their machines, especially if the warranty is finished. So, if you know what you’re doing/looking at, I think you might be able to handle it. Below is a photo I found of the MNM’s battery, still in place on the motherboard. It looks like it’s just held there by tension, and not soldered in place.
