z50 battery oddity
I got out my z50 today, and it wouldn't turn on. So I plugged in the
mains brick/charger and it then would, but it was acting odd: the
battery light (normally off when on battery, orange when charging,
green when charged) was blinking between green and orange (rough
estimate: .5 sec orange, 1 sec green, repeat). Listening closely in a
quiet environment, I can hear a soft click when it switches from green
to orange and a very slight high-frequency noise while it's orange.
The click sounds like incidental mechanical stress from an electrical
change, not a mechanical switch.
It booted apparently normally and I was able to do what I wanted to do
(see if a PCMCIA card I dug out of an old box-o'-stuff did anythiing
useful). While I had it up, it seemed to flip between battery state
critical and battery state high randomly (according to the kernel
messages), and, no, I'm not running any kind of non-kernel power
management software. (The kernel in question is 3.1.)
I tried removing and replacing the battery; this made no apparent
difference. Pulling the AC power plug produces an ungraceful shutdown
which produces a cold boot when I next wake it up.
Any ideas? Is my battery toast? It was fine last time I used the
machine (I put something like 30-60 minutes of run time on it; it
normally has given me about two hours of run time on a full charge).
