|Is the '42S a battery hog?|

The batteries just pooped out on my little-used 42S. It is one of the service units that were discovered two summers ago.
I haven't used it all that much, generally preferring my 41C , 41CX, and 11C for daily use. Maybe I am spoiled by the battery lifetimes on these latter units, but I am rather surprised that the 42S quit so soon. I doubt that it has even 20 hours on the battery set, whereas the older units get hundreds of hours on a set of batteries. (I use them regularly for MANY years, 5 to 10, before having to replace batteries.)
The little battery anunciator appeared above the two numerical display lines - for only a few minutes - before the batteries really died. This seems like a rather short warning interval!
I don't remember whether the dead batteries are ones that came with the calculator when I got it, or whether I had to put new ones in. If they are the originals, I can be somewhat forgiving - they probably sat around for several years. They are Panasonic LR44s - is Panasonic the HP OEM brand?
Might I have something turned on that shouldn't be - like the IR link? This calc didn't come with a manual. Could there be an internal short?
Also, it sits in a drawer most of the time. I don't think the ON button gets mashed in there, but it might. In any case, though, I would expect it to be turned off relatively quickly. What is the default turn-off time? I'd guess 5 or 10 minutes. (Can I change this?)
