Acer Aspire 5 - (A515-43) having charging issues
I bought three Acer Aspire 5 - A515-43 laptops in the summer 2020. I had one laptop have charging issues while it was still under warranty and sent it away and it got repaired. Now that my warranty is expired (laptops are 18 months old now) I have 2 laptops not charging anymore. When I plug the charge cord they charge for about 20 seconds then stop charging and go to battery power. If I disconnect the battery internally and plug the laptop in it works fine. If I swap the a good battery the behavior doesn't change. So it seems there is an issue with the charging mechanism on these laptops. Any ideas where I can get the charging chip or new motherboards for these laptops or what I should try next?
Thanks
