   So then Li-ion batteries are better off kept near full charge, rather   
   than discharged as NiCd/NiMh ought to be?

   My MP3 players have a built-in rechargeable battery, charged from the   
   USB port.  I assume that's NiMh.

   Yes, I've noticed those on my chargers for household-sized (AAA, AA, C,   
   D, "9V") NiCd/NiMh batteries.  I remember around the 1970s there were   
   also "rechargers" meant for disposable (carbon-zinc, heavy duty,   
   alkaline) batteries, but those were separate chargers from the ones for   
   recyclables.  I sold a few of those at Radio Shack, but I don't think   
   they lived up to their claims.   
      
   By coincidence, I'm about to organize and check all my household-size   
   NiCd/NiMh batteries.  They've been untouched since September, so I think   
   I can consider them completely discharged.

   OTOH if a new battery would be too expensive, I could just get rid of   
   the laptop, which wouldn't have cost me anything anyway.

   That was on my TRS-80 (Z80 CPU), also limited to 64 KB.  IIRC that   
   program left about 38 KB free for the document.  I was very proud of   
   being able to add numerous features to that program without taking a   
   single byte away from the space for the document.  Not a trivial task!

   Last night I tried to use okular to print out a small-sized (5"x5")   
   document at two pages per sheet, but couldn't get it to work.  I then   
   got evince from the repository and will try that.  I tried it on my   
   previous computer and it worked well, apart from simply refusing to   
   print a few pages of the document.
