Hi Frank:
I tested the AC adapter with a voltmeter, and I am getting just under 3
amps and about 7 volts DC.
Here's the part I can't explain: today I can remove the ac adapter
from the Newton and the Newton continues to run. I can also start the
Newton with the battery pack removed (while connected to the AC
adapter). So today, it seems to be working fine.
The only thing I can think that might have changed is that I wiggled
the prongs on the AC adapter yesterday to get the Newton to recognize
the AC adapter (I was running under battery power at the time and I
watched for the Newton to "see" the AC adapter). I wonder if there was
some oxidation on the AC adapter prong connections (inside the AC
adapter) that was preventing good contact on the terminals. The AC
adapter does not show any obvious oxidation on the outside, but I had
not used it in several years, and that may have caused the connections
inside the AC adapter to become oxidized.
Does that sound plausible? Or do you think my AC adapter is going bad?
Thanks, Scott
