I recapped my two M100s. The first one required some flux-cleaning and then worked fine. So I put it on its shelf, and recapped the second one. After, the second one was completely dead; no battery light, no sign of life whatsoever. I took it apart again and thoroughly cleaned it with alcohol because I'd been told that excessive flux could be an issue. I also checked all the capacitors and the battery to ensure that they were all soldered properly. They all appear to be so.
After reassembly, it was still just as dead. So I returned to my first M100, intending to install a RexCPM into it. Before doing so, I flipped it on, and the low battery light came on... and nothing else. I replaced the batteries with new ones... and all that happened was the low battery light flickered as I turned it off. I adjusted the contast knob, just in case it was something that simple, but to no avail. So I put it back on its shelf to deal with another day, saddened that I now have no functioning M100s; that I killed them. A few hours later I took it off the shelf... still the battery light flicker, but, I accidentally pressed several of the keys. Whenever I press a key, I get a beep. Can anyone with more experience advise me on how to further investigate what could be wrong with my machines? At this point, I'll settle for one working.
