I would first check to see if the headphone jack is loose and try plugging it in all the way. If that's not the problem I would next try to see if there is any debris in the jack and after cleaning that and it still doesn't work, I would then try replacing the headphone jack. Hope this helps!!

I would first check to make sure that there isn't any debris in the charging socket or battery socket. If after cleaning out the sockets and still no charge, then I would ask a friends for his/her charger and if that works then you need a need charger but if not I would suggest replacing the battery. Hope this helps!!

First I would start by checking your recycling bin and empty that. Your recycling bin is located on your windows desktop, click on that and go to the manage tab and then click empty recycle bin. Another solution would be to delete any unwanted programs. In windows search for Programs and Features and on there you can scroll through all the programs and choose which ones you would like to remove. Hope this helps!!
