Hi Adinahc,
Performing a full reformat recovery using the disc should resolve the issue if done properly. You may check out this link to verify if this is how you did the system recovery, https://us.en.kb.sony.com/app/answers/detail/a_id/40172/related/1. If so, then you may proceed to the link below. If not, then we suggest that you redo the reformat using the steps in the above link then duplicate the issue.
For the battery issue, kindly refer to this link for troubleshooting steps. https://us.en.kb.sony.com/app/answers/detail/a_id/43943
