Bought a new laptop battery as my old one kept getting error message on charging. New one worked for a couple of weeks, and now getting the same error messages "battery plugged in, but not charging". Have tried ALL the fixes recommended. Beginning it think it's something with the software or something. Does anyone have a permanent fix for this? Can only use my laptop plugged in as charging keeps going down. This week it's down from 59% to now 30%. Really upsetting.
