Hi,

this looks a little strange:

My laptop battery today has stopped charging. If you connect the PSU,
it will charge for about 20 seconds, then stop, but the machine then
runs on the battery, not the PSU.
Every time you remove the PSU cable and re-insert it, it will again
charge for about 20 seconds before stopping and again running on the
battery.

It is not the PSU socket, as the same thing happens if you remove the
PSU's mains supply instead.
I have tried another PSU, exactly the same.

I have removed the battery, and the laptop is happily running on the PSU.


Why would the laptop run on the (faulty?) battery rather than just
switch to the PSU?
It was saying it was charged to 60%.

Any tests I can do to see if it is is the battery, or something in the
laptop?



Cheers,



Gareth.
I had a laptop that did that. Sorry, don't remember the make.
When the battery thinks it's abused or exceeded some preset limit,
it has mechanisms to force you to get a new one.
Mine would run on AC if I removed the battery.
It would charge if it was off.
If the battery was installed, it would only run on battery.
Searched, but never found a way to reset it.





Didn't think to check, but I think this one is charging with the machine off
too.

Well, an orange LED is lit with the battery present and not when it isn't.




Thanks,

Gareth.
