I would operate the computer on the battery until it runs down, then
(after a
rest) recharge it and see what happens.

Yep, that's the most likely scenario. There are a few charge anomalies
that can
be fixed with updates to firmware (it never hurts to check with the
laptop
manufacturer).



Clearly you haven't read the thread.



The laptop, suddenly, over the course of one day, stopped charging the
battery for more than 20 seconds after repeated reconnection of the PSU
(charger).

I noticed this problem at around 60% reported charge.

The laptop refused to use the PSU, but instead kept using and not
charging the battery, yet worked fine on the PSU if the battery was
removed.

I watched about 2 hours of TV on demand on the now 50% charged battery
before it ran out, so clearly the battery itself was OK, it was the
charging process that wasn't working.

This is consistent with my experience of the machine quite capable of at
least 4 hours running on a full battery.


I fail to see how any firmware settings can direct the laptop to use a
non charging battery in preference to the connected PSU.

Clearly something here is broken.

Assuming its more than 2 lines between battery and laptop. Can you fudge a
multiway linkage between them so the battery can be outside its rightful
place. Then try jumpering in a single charged cell in the power line and
genearally monitor what happens to operation and the other control lines




I've some teeth to pull out first, maybe I'll try that later
