It sounds like a bad battery. At least I have had the same thing
happen in both Linux and Windows when a battery was going bad. Also,
if you do not cycle the battery, the chip that monitors battery life
in the battery does not get updated to the current battery life, so
it ends up reporting the battery state incorrectly. (The chip is in
the battery, not the computer.)
How do I get the battery to cycle? It HAS been a long time since a
REAL poweroff (number of reboots). Also I have not run the battery
down for a long time. Really not since I got the system back in
Jan... I bet I am past my 90 day warranty...
Sorry for the late response. This is normally covered in the user's
manual. What you do is first fully charge the battery. Then you
unplug the power and let the system run down until it does an
automatic shutdown. Then you charge it up again. Some systems come
with a utility that runs the battery down, so you do not have to
worry about your OS shutting the system down too soon.
I did this when I first got the unit. And it SEEMed to run fine for 2
months with few power offs.
And it was working just fine a couple weeks ago. My practice is friday
afternoon to suspend then shut off on the powerstrip (turning the KVM,
switch, AP and other sundries off). Saturday night I would power up and
have 80% power left. It seems that two weekends ago, it when blewy, as
it cold booted that saturday night. I fought with it all week and then
on friday realized I had a battery problem.
Now with the new battery, how with Fedora, am I going to run down the
battery? I don't see that IBM has a Linux utility for this, oddly enough...
