Lisa 2/10 question

Hi! I was just offered a Lisa 2/10, which I will happily accept. I do have the 2/5 but the second would be nice, albiet a tad greedy. :) However he wants me to name my own price, and said that it wasn't working. Apparantly the self test and stuff works, but it doesn't boot up - I assume this to be a problem with the hard drive, but imagine that it could be something else. Does the 2/10 have the battery problem found on the 2/5, and is this particular error the sort of thing that can be repaired given that it does start? I had imagined that a serious error would not allow it to start at all. :) If it can't be easily fixed I'll probably buy it anyway, but I don't want to offer too much (as I have almost no money) but I definitly want to save it. Thanks heaps, Adam.
