I have a Spectre x360 which has been excellent since I purchased new from HP and never had any problems with it. I also am a Mac user, so this Windows notebook isn't used daily. I've recently tried to charge it and it won't charge. There's no indicator lights at all and the AC charger is is working. I've read that HP is aware with these particular models. Unfortunately, the laptop is out of warranty (just my luck). Please help!
