This is really kind of a no-brainer tip and hardly worth posting to the
mailing list... But it got my M100 working after I freaked out for an
evening about it:
When I got my M100, I couldn't get anything to display on the screen. I
freaked out and popped her open. I twiddled with a few things, but
nothing seemed to matter. Then I gave her a nice new set of batteries
and it all was happy. I thought I'd put fresh ones in, but apparantly
they weren't fresh enough to drive the LCD.
OOoooh, you scared us! :)
Did you used those stupid "renewal" kind? This Renewal and even
rechargeables does not give oomph as well. Some really prefer very
strong batteries like Energizer, Duracell and compareable quality $1
stuff. It takes a while to find cheap ones that does equally as good
ones. I did find specific brand that does pretty good.
Racvac, it have no punch at all bec it's carbon based technology and
it's good for some other things.
Did this M100 needs 4 AA cells? That gives about exactly 6v for
that 5v regulator and LCD stuff to work if cells drops past about
1.1-1.2v the usually LCD fades out then crashes the machine because
it's 4 cell design. If Tandy designed 5 or 6 cells for M100 years
ago, it will run past 1v per cell and extends the running time!
Fresh batteries are just about over 1.5volts each. Similar topic on
voltage changes: my hearing aids uses those 1.5v 765 type. When
that cell start to die, I start to hear distorted sound and general
fading (twirls the bitty tiny volume knob) when voltage drops past
1.2v or so then dying to silence. <DART!> Don't have the cell with
me when outwhere nearest any suitable resellers. If someone
wonders, typical hearing aids sometimes helps hearing impaired but in
my case, I'm profound deaf. I can only hear sounds and understand
genernally different sounds (screaming, banging, engine purring and
backfiring, baby crying, train tooting and such.) But not able to
understand normal frenquencies like talking. But I assure all that I
can hear the world around me going on.
On this side, I saw one worst battery kind when I put 'em into
flashlight, it lits up brightly, immiately fades out. (!). They're
were new!
