- The clue to both of these puzzles is: The Ether Wind. Batteries tend
- to drain at different speeds depending on their Absolute Position in
- The Universe due to the effect of the Ether Wind (see any pre-'1881
- physics text). Although most users carry their HP 48 about, and
- randomize its position enough, some users apparently are so sedentary
- that they keep theirs in one Absolute Position long enough to give the
- battery(s) facing one direction constipation, and give the other(s),
- uh, a higher rate of drainage.
-
- If you find that the battery(s) facing a particular direction always
- die first, I suggest any of the following to neutralize this effect of
- the Ether Wind and to make your batteries last as long as possible:
-
- (1) Keep your HP 48 wrapped in several layers of lead foil. (You can
- have a hole above the display, since the batteries are at the
- other end, and you know the keyboard by heart by now anyhow). If
- you use the HP 48 a lot, you can avoid lead poisoning by covering
- the lead foil with a layer of aluminum foil. (Helpful hint: also
- keep your spare batteries refrigerated and individually wrapped in
- lead foil).
-
- (2) Hold the 48 rightside up one week, then upside down the next week,
- and so on. You'll probably want to switch hands, too, since your
- wrist will tend to cover the display otherwise. You can get used
- to it in just a few months.
-
- (3) Store your 48 at night on a rotating object, such as a microwave
- oven's turntable. (Do *not* tie it to the blade of a fan,
- however, since the centrifugal force will distribute the electrons
- unevenly in the batteries causing the electricity to get clogged.)
-
- (4) Stop being such a couch hacker; program while driving, skiing,
- skydiving, and other mobile activities.
-
- (5) Use a marble slab, pool of mercury, laser beam, mirrors, and
- diffraction grating to determine the direction of the Ether Wind,
- and rotate your couch accordingly.
-
- Sorry to belabor the obvious, but people keep asking.
