A problem in V30 firmware for the DM1x and DM41 models has been identified.

The problem causes excessive load on the battery, which is depleted far sooner than it should be.
Jeez I reported this on February, 27.

Only took 3 months before it got confirmed ;)

Re: Firmware V30, DM15L and battery ?

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...

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.

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

Firmware V30, DM15L and battery ?

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 a...

Re: How did you discover SwissMicros?

A few years ago I needed a scientific calculator for the first time in years. So I wanted to purchase an HP RPN of course. Only to discover that they didn't make any of the series I loved and what seemed to be the closest to it was the HP 35S. So I bought one and immediately disliked it, although it...

Re: What is the downside of using the M80 or M1B firmwares for the DM-15?

Next exercise is to try to restore my programs I already made. :) IMHO the best tool for backing uo and restoring DM15 programs (and even progamming on the PC and get readable listings) is Torsten Manz's excellent simulator : http://www.hp-15c.homepage.t-online.de . It can communicate directly with...

Re: DM15L keyboard faceplate is separating

Although this shouldn't calm you down as a customer (and it doesn't justify the problem), I would try this in your situation: 3M 2mm double side adhesive Because it has only 2mm width size, you can put it between the keys horizontally and you don't need to cut out the keys. I tried exactly this. It...
