Q: Why can't I unzip this file?
A: This isn't really a 100/200LX question, but it's been asked
frequently enough.  PKZIP works the same on the 100/200LX as on any
other MS-DOS machine.  Chances are you don't have your file transfer
software set up in binary mode.  If you're absolutely positive that
the file was transferred in binary every step of the way, then maybe
you have an old version of PKZIP.  2.04g is the most recent as of
this writing.

Q: I can't turn it off while it's charging the batteries!
A: That's right.  It needs to be awake to monitor and regulate the
charging rate.  LCD screens don't suffer "burn-in" from continuous use
(think about LCD watches), so it's really nothing to worry about.

Q: Help! My machine is stuck! What do I do?
A: The manual's "Getting Started" chapter contains some suggestions.
Try the following, listed in order from least likely to destoy data
to most likely.

1. Reboot with cntl-alt-del.  If the machine starts to boot, but freezes 
   up during the boot process, you have a problem with something in your 
   config.sys and/or autoexec.bat.  Boot from the D: drive (press alt 
   during boot for menu) and use the memo editor to remove the offending 
   line(s) from the startup files.
2. Press cntl-shift-on.  Cntl-shift-on will ask if you want to destroy 
   your C: drive, so be careful.  It will also alter battery settings 
   from the setup application (if you were using NiCads, for example).
3. Replace your AA batteries with fresh ones and try again.  Replacing 
   batteries while the machine is hung up may destroy the data on
   your C: drive.
4. Remove PCMCIA card and all batteries, including backup battery,
   from the 100/200LX (but if you have a SRAM card, leave its battery
   installed while the card is out of the 100/200LX!).  Let the machine 
   sit without power for awhile, and reinstall fresh AA batteries 
   BEFORE replacing the backup battery.  This will, of course, 
   erase your C drive, reset the clock, and in general make the 
   100/200LX forget everything you ever taught it.  Data on the
   PCMCIA card should survive this process, unless you have a SRAM 
   card with a dead battery.  But there's no guarantee that your
   PCMCIA card wasn't already trashed by whatever crashed your system.
5. If none of this works, your machine may need service.  Try running
   diagnostics by pressing esc-on, and following the menu if one comes
   up.  Follow the instructions in the manual for obtaining service.

Any time any MS-DOS machine crashes hard enough to require a reboot,
it's a good idea to run chkdsk on all drives, to clean up the file
systems and recover any clusters that may have been lost.

Q: How do I fix a loose hinge?  A loose latch? 
A: First, call HP and see if you can get them to fix it, preferably
at no charge under warranty.  Both the hinge and the latch problem
seem to be somewhat common after a year or so of use.  Posters have
generally had very good results with HP's express exchange service in
dealing with these under warranty.  If your unit is currently under
warranty, you may be able to extend it by two years by paying a fee.
Contact your country's HP branch for details (see the manual).

To fix the hinge yourself, pull off the left end cap (it should come
straight off using no tools harsher than a fingernail), and insert a
rubber band in the vertical slot under the cap.  Trim off excess and
replace cap.  You probably just voided any warranty you may have had.
Be careful not to get the hinge too tight, or else it may break after
repeated use.

To fix a loose latch yourself, you can stuff something compressible
behind the latch.  Posters have suggested rubber bands, surgical
tubing, packaging foam, and other similar materials.
