You're a dense prick, my longevity quote was clearly an "I'm not a
sap(newbie)" statement because GMAN's answer was obviously rushed.
While your's is clearly all about competition as with the sarcasm. I
know a man that's been with various women for over 67 years and still
doesn't know how to treat them. Obviously long lived exposure doesn't
necessarily equate with knowledge. Grow up boy and stop using computers
to release your misplaced frustrations.

Check out Paul's response. He's got class and it has nothing to do with
his knowledge, but rather his attitude. He seems to really want to help
someone, A TRUE Gentleman and Scholar. You sound like a washed up
loser, get a grip. Thanks for nothing!

Thanks a lot Paul. I really appreciate the length at which you'll go to
help someone. And unlike some people, you address the problem and not
the symptoms. Very professional in deed (indeed)!

Now I'll take some time and mull over all the resources you've been kind
enough to provide.

Again thanks much. I hope I can someday repay you, or maybe it will
just be enough to pay it forward. ;-)

Have a good one!

Joe, I have the Rev 2.xx version, and I had a similar problem, just
slightly different, and replacement of the battery did the trick.

Give it a try.

Stranger things have happened, it's just another "funny" that can
only be explained at significant cost and effort, much greater than
the $2.99 cost of the battery. Chill.

How did you know I had a can of chill? Do you mean the CMOS EPROM or
one of the diodes Paul referred to?

I find it hard to believe that your kind can be so presumptuous. I have
not sought your council on interpersonal relationships, but rather
batteries, MB's and EPROM's. A wise man such as Paul knows that you get
what you give. That Psychology dictates that I'm a mirror, what you see
is merely you only clearer. Or in other words what you see in others is
a mere reflection of yourself, after all, you is all you truly know and
that's not certain. So I'll give you the same unsolicited deluded
condescension that you gave, CHILL!

It would seem that you're the singular altruistic group member here. I
of course don't include any like minded that have yet to have a voice in
this thread. I humbly respect those that humbly respect. I hate with
disdain those that hate with disdain. Hey I really am a mirror. But
seriously thanks!
