Dan,
I concur with Graham. Sounds like your battery has served its life and
is ready for retirement and recycling. Also sounds like you ought to
reset the NVRAM and the PMU.
Something I have heard, often actually, is that when you are using your
notebook computer as a desktop, then take the battery out and store it
in the refrigerator. I have never done that, yet I know that the cooler
one keeps the battery, then the longer it will last per charge and the
longer life it will have. So storing batteries in a cool place makes
sense. I would seal it in an air tight zip-lock bag with a desiccant
pouch to keep it clean and to keep moisture away. Does anyone have any
experience putting the battery in the 'fridge while not in use? If so,
what were the results?
Best regards,
Scott

I would fully expect that your battery is beyond rejuvenation if it's
been
used full time as a desktop. In general I recommend to folks to remove
the
battery from the machine if it's likely to be used in this way as it
kills
batteries in my experience. A new/spare battery needn't be that
expensive or
hard to find.
It would probably be well worth resetting your NVRAM anyway - you've
got
nothing to lose so long as you are on power.

Hi Listas
I have Ti-Book 800MHz with 1gig of RAM, and a 155 GB firewire hd
attached. I'm running 10.4.1. I've been using this machine as a
desktop unit, always on and plugged in. I probably killed the battery
that way but ever since I installed Tiger, I can't restart or shut
down without forcing those functions. I unplugged the charger to see
how long the battery would go for... the battery shows 98% to 100%
charge all the time... but when I unplug the charger I get about 7
minutes of battery time and then it reads 0. I'm wondering if these 2
symptoms indicate corrupted NVRAM. The fact that it no longer
completes a shutdown is what makes me think so. The battery may still
have some ability to recharge if I reset the PMU. Anyone have any
thoughts on this? Thanks for your thoughts.
