I did a video last year on fixing a M100 with the same issues. There is a link in the description to a color-coded map of the electrolytic caps and part number for replacements. I used a super-cap instead of a battery, but it won’t last as long backing up the memory (perhaps 3-4 days compared to a few weeks or more with a battery.) For a battery use a NiMh I don’t have a part number to hand but I’m sure somebody will chime in with one.

I found them in the archives; I'm not sure how to access the (current) list itself. I couldn't find a "reply" option on any of the messages. I'm also not sure why the JPG picture I attached was "scrubbed" from my initial message. As I said, I've got a lot to learn... But THANK YOU for pointing out the possible problem with the rechargeable battery. When I first got the machine, seven days ago, I tried turning it on; nothing happened. Then I tried turning it on with a 6 VDC adapter - again nothing - and finally inserted four fresh AA alkaline batteries. Eventually it came up. I knew there was a rechargeable battery that maintained settings but I would have assumed it merely needed to be recharged. I opened the case just now and found that the battery had indeed corroded its case and possibly leaked onto the circuits adjacent. I'd show you a picture but I don't know how to post one... However, this repair, now prioritized, raises some questions of its own. I didn't see a wiki on how to make this repair so allow me to ask: - What do I need to look out for when removing the circuit board? - Which battery and what voltage for a replacement? 3.6 V? NiCd? Li? - What do the gurus recommend for cleaning the traces? Gonna get right on this. Thanks again. -CH- <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> www.avast.com
