I got two Macintosh LCs in today, with the plan of making at least one relatively nice and working unit out of it. I've made a video about it:
You've gotten me to look at MO drives now, I think I have another hardware fascination now that'll drain some of my money :lol:
You'd think that, but the eMate specifically has "1.2A MAX" written on the power specs on the bottom of the laptop.Current is drawn by the eMate, so a 2A adapter should be just fine as the eMate isn't expected to draw more than 1.2A. The error is probably coming from some battery management system noticing that it's putting juice into the battery but the battery isn't recharging.

From reading the Wikipedia page about NiMH cells, and their charging methods, I think there is a good reason for the maximum amperage rating. The eMate battery pack has a thermistor, that monitors the temperature while charging. As soon as the cells get full, the incoming charge is turned into heat, which signals the charging circuit to stop. I think with a higher amp adapter, it will notice much quicker heat build up, and perhaps it also notices the input power doesn't drop as much as the 1.2A charger would.FWIW, I just managed to reproduce this error with the stock adapter and a dead battery (I thought I'd seen it before! I normally run my eMate batteryless). So I'd look at the battery first.
Indeed. That would seem to be a very poor design on Apple's part if that is the case.That would suggest to me that the charging circuit isn't doing its job, if that is the case; regulating the current to maximise charge on the battery without thermally overloading it is... quite a lot of its job.
