Firmware V30, DM15L and battery ?

Post by michel_b » Thu Feb 27, 2020 3:10 pm

Hi,

I'm not sure if this is relevant, but I wish to report here that my DM15L battery died a few days after I updated its firmware to V30 :o

Battery readings just before didn't let me expect the battery to die anytime soon...

I also own a DM15 that got updated a couple weeks ago and didn't exhibit any battery issue so far. So it might be a coincidence.

Kind regards.

A coincidence for sure - but presumably you wanted to tell it might have been a chance coincidence, didn't you?

Dunno... As long as nobody replies “mine too” it's a coincidence ;)

There's important difference between "true coincidences" and "chance coincidences" in physics at least. ;)

(Might be caused by language: English "coincidence" seems being narrower than German "Koinzidenz" - the latter encompasses also causally connected events.)

Coincidence = Zufall, not Koinzindenz, unless it is clear from context that the other sense is intended. I guess the term of choice for Zufall used to be "chance," as in "a chance encounter," but that seems to have largely fallen out of use.

The verb "to coincide," however, does still refer to things occurring together, regardless of causality or the lack thereof.

Well I'm french, and in french “coincidence” stands for 2 things that appear together without a causal relation between them even though it might seem.

And I am Norwegian, and understood perfectly what you meant in the first place! :D

I would just like to contribute that on my DM42, the previous battery lasted only a few days, but the current one has been working fine for weeks now. I was in the process of updating it, but ran into problems with the USB connection and had to leave it for a few days. If this is interesting for SM I can provide more details.

PS: I consider my incident a fluke. Oxford Advanced Learner’s Dictionary, 9th edition (app edition) if anybody cares...

Well, I have to insist.

My DM15L has run for about one year on one battery, since I upgraded to FW V30 the battery died in a week, I've replaced it, the new battery lasted only 3 weeks, I replaced it a month ago with another one from another brand and batch, and well... It's down to 2.1V by now...

Have you contacted Swiss Micros? The cure for mine (DM42 beta) was a hardware fix, but it occured conspicuously close to a software update.

Yes, definitely contact Michael by email, it does sound like a h/w issue.
