Well, I finally got around to replacing the battery pack, but now that
it's working again, I've noticed a couple of peculiar things about the
display:

1. It whines.  Not too loud, but noticable, and probably annoying if I were
to use it for an extended period.  The volume of the noise is proportional
to the brightness.  The display quality itself is fine.  Is this a normal 
characteristic of this unit?

2. The system used to boot up with the display on, now it boots up with it
off (until the LCD/CGA key is hit).  Is this a user configurable option?
In EEPROM or by DIP switch? I did have the motherboard out in the process
of fixing some melted wiring, but the display behavior didn't change until
a couple of boots after it was reassembled.  I don't have the manual to
consult, of course.

Any helpful information would be most appreciated.

Regards,
