Another acer aspire one AOA150 battery issue. Sure it is old but it works well when plugged in and I have been using it like that for a few years. However I need to be able to run it off of the battery so,,,,My bios has been upgraded. I am running puppy linux and the desktop icon shows fully charged, yet in the device manager shows the battery is not detected.
What to do ?

and thanks
