Mac SE NVRAM battery removal

[John Rollins]

You just made me think that I need to go check on some of my stuff and see what the batteries are doing… Been quite a while since I used a lot of them.

On an old Mac, quite often the reason for a machine to not boot at all would be a dead PRAM battery, so complete removal may not be an option. You could test it, but don’t expect much. As for what is stored in there besides date/time, a quick search shows that it is likely storing data on startup disk ID, AppleTalk status, monitor settings, volume, mouse speed, and energy saver settings.

(I'm not inclined to replace batteries unless I have to, just so I don't have to worry about replacement again in x years time)
