Re: [Thinkpad] [tp765L] Power questions

Hi David,

Well, the only thing I can imagine at this stage is maybe you're right
and the dc board somehow is faulty in some way ~ but it would be
a first for me. Here's a crazy idea ~ do you think, just maybe that
particular led light burned out ? Man I can't remember ever seeing
any of those burn out ~ but there's always a first time. Try testing
the battery you or your friend has too with a voltage meter. You
should be able to get some readings ~ if not, then we're definitely
back to square one ~ the battery may just be faulty after all.

btw ~ i just got the two post I just sent Jane and that one I actually
I edited it and took Jane's address off the list so only stderr.org
is showing. I'm sure to get two of these, but I think some of you
shouldn't be getting double from me anymore. I'm just going to
do it this way for now until i can find a better solution to the problem
and or just not create additional e mails on my part.
