T23 shuts off during boot while charging

[kg0wx]

I have a 2648-1u6 T23 and I just bought a new battery for it. It came
with a 65% charge which I topped off then ran the laptop on the
battery until it shut off. I got 3:39 out of it which seems to be right.

2 problems, though -

1) The capacity meter showed 7% remaining when the system shut
down - was that simply the electronics and or software needing to
be calibrated by doing a deep cycle?

2) A more serious problem - after the system shut down, I plugged
in the 72w power supply and powered up the computer. I got 90%
booted up (Win 2000) and then the thing shut off again. Repeated
the effort and it kept happening. I finally guessed that maybe the
battery was pulling down the power supply so I took it out and then
started the system. It booted normally that time and I reinserted
the battery to charge. Now all is well but I haven't "pushed my luck"
by rebooting with the battery in yet. (chicken)

Are these all new battery issues?
