Inspiron 15R N5110 Plugged in Not Charging
I've tried everything to fix this problem before asking for help here, but nothing seemed to work. Then I noticed on BIOS that this AC adapter isn't being recognized even though I've been using this same adapter since I got this laptop in March of 2012 (manufactured by Dell of course). Recently, like almost a month ago, it stopped charging completely and the speed of my browsers slow down considerably as a result. Currently I have 37% available battery left, and I was wondering if I should get a new AC Adapter. Or is it the batteries' fault?
I don't want to buy a replacement until I can confirm that this is truly the problem. Help would be appreciated, thanks.
