I hope this is ok to post here.
I have had this problem for a while now, my laptop hasnt been charging very well if at all, but luckily my mum has the same laptop so I used her charger for a while which seemed to work. But now it won't charge on either and my laptop went completely dead last night.
But today I tried switching the battery from mine and my mums laptop, and that worked fine. My battery charged in her laptop, and her battery worked fine in mine. But when I switch them back, I can no longer charge it.
What could be the problem here?
